🐶 Biscuit: a web chatbot on the Pi 5 + AI HAT+ 2 · บิสกิต: แชตบอตบนเว็บ บนพาย 5 กับ AI HAT+ 2 · Biscuit:树莓派 5 加 AI HAT+ 2 上的网页聊天机器人
A Raspberry Pi 5 with an AI HAT+ 2 serves a chat page to every phone on the Wi-Fi. Biscuit, a cartoon puppy, runs on the HAT: it chats, remembers the chat, and answers the buttons: a coin's price, a map, a web search, a web page. ✨ Auto is a ReAct agent on real Ollama, on the Pi's own processor, that picks those tools itself. This page describes the Pi as it is set up and the code as it runs, on 30 September 2026. Every log was made on the Pi, and every code block is cut from the file that runs. · ราสเบอร์รี่พาย 5 กับ AI HAT+ 2 ให้บริการหน้าแชตแก่มือถือทุกเครื่องบน Wi-Fi บิสกิต ลูกหมาการ์ตูน รันบน HAT: มันคุย จำสิ่งที่คุยกัน และตอบปุ่มต่าง ๆ: ราคาเหรียญ แผนที่ การค้นเว็บ หน้าเว็บ ✨ Auto คือเอเจนต์ ReAct บน Ollama ตัวจริง บนตัวประมวลผลของพายเอง ที่เลือกเครื่องมือเหล่านั้นด้วยตัวเอง หน้านี้บรรยายพายอย่างที่ติดตั้งอยู่ และโค้ดอย่างที่รันอยู่ ณ วันที่ 30 กันยายน 2026 ทุก log ทำบนพาย และทุกบล็อกโค้ดตัดมาจากไฟล์ที่รันจริง · 一块装着 AI HAT+ 2 的树莓派 5,给 Wi-Fi 上的每一部手机提供一个聊天页面。卡通小狗 Biscuit 跑在 HAT 上:它聊天、记得聊过的内容,并回答各个按钮:币价、地图、网页搜索、生成网页。✨ Auto 是真正的 Ollama 上的 ReAct 智能体,跑在树莓派自己的处理器上,自己挑选这些工具。这一页描述 2026 年 9 月 30 日树莓派的真实配置和真实运行的代码。每一段日志都在树莓派上生成,每一段代码都从正在运行的文件里截取。
Four parts. A is the Pi: what is on the desk, what is installed, the two accounts, the six services, where every file lives, and the heat. B is the two model servers: the HAT's own, and real Ollama beside it. C is web_factory.py, the one file that is the chatbot, read part by part. D is running it, changing it and sharing it, and the numbers that were measured along the way.
The chatbot is built on the classes page's window_factory.py: the same idea, a factory that builds a class with type(), moved from a tkinter window to a web page. If type(name, (), inside) looks strange, do challenge 8 there first.

NO FANNothing cools this Pi but air: /sys/class/thermal lists no cooling device. Biscuit on the HAT keeps the processor near 50 °C. ✨ Auto runs a model on the processor, and two questions take it to 75 °C or more: section 10. The official Active Cooler fits under the AI HAT+ 2, and is the first thing to add.พายเครื่องนี้ไม่มีอะไรระบายความร้อนนอกจากอากาศ: /sys/class/thermal ไม่มี cooling device เลย บิสกิตบน HAT ทำให้ตัวประมวลผลอยู่ราว 50 °C ✨ Auto รันโมเดลบนตัวประมวลผล และสองคำถามก็พาไปถึง 75 °C หรือมากกว่า: ส่วนที่ 10 Active Cooler ของทางการใส่ใต้ AI HAT+ 2 ได้ และเป็นสิ่งแรกที่ควรเพิ่ม这块树莓派除了空气没有任何散热:/sys/class/thermal 里没有 cooling device。HAT 上的 Biscuit 让处理器保持在 50 °C 左右。✨ Auto 在处理器上跑模型,两个问题就能到 75 °C 以上:见第 10 节。官方的 Active Cooler 能装在 AI HAT+ 2 下面,是第一件该加的东西。
THE CARD READER WAS NOT THE FIRST PLANThe laptop here has no card slot. The first plan was rpiboot, which makes a Pi show its own card to a computer over USB. The Pi never showed up. The cable only carried power, and rpiboot's own notes promise eMMC and NVMe drives, not an SD card. A card reader for about 150 baht did it in two minutes.แล็ปท็อปเครื่องนี้ไม่มีช่องการ์ด แผนแรกคือ rpiboot ซึ่งทำให้พายโชว์การ์ดของตัวเองให้คอมพิวเตอร์เห็นผ่าน USB แต่พายไม่เคยโผล่มาเลย สายเส้นนั้นส่งแต่ไฟ และคู่มือของ rpiboot เองสัญญาไว้แค่ไดรฟ์ eMMC กับ NVMe ไม่ใช่การ์ด SD เครื่องอ่านการ์ดราคาประมาณ 150 บาททำเสร็จในสองนาที这台电脑没有卡槽。第一个方案是 rpiboot,它能让树莓派通过 USB 把自己的卡给电脑看。可树莓派一直没出现:那根线只通电,而且 rpiboot 自己的说明只保证 eMMC 和 NVMe,不包括 SD 卡。一个 150 泰铢左右的读卡器两分钟就搞定了。
2The software, and its versions · ซอฟต์แวร์ และเวอร์ชันของมัน · 软件和它们的版本
🇬🇧 English
These are the versions on the card today. Newer ones will probably work; if something breaks, compare with this list first. Two model servers hold the models: hailo-ollama runs six on the HAT, and real Ollama runs one on the processor. The Python libraries live in the student's venv, ~/web-venv.
这些是今天卡上的版本。更新的版本多半也行;出了问题,先和这张表对一对。两个模型服务器各自装着模型:hailo-ollama 在 HAT 上跑六个,真正的 Ollama 在处理器上跑一个。Python 库都在学生的 venv ~/web-venv 里。

"Hello, class!"
WHY STEP 3 COMES BEFORE STEP 5Boot the bare Pi first. If the HAT is on from the first boot and nothing works, you cannot tell a bad card from a loose ribbon cable. They look the same. Here, lspci without the HAT showed only the Pi's own chips. After the HAT went on, one new line appeared. That one line is the proof.บูตพายเปล่า ๆ ก่อน ถ้าใส่ HAT ตั้งแต่บูตแรกแล้วอะไรก็ไม่ทำงาน คุณจะแยกไม่ออกว่าการ์ดเสียหรือสายแพหลวม เพราะมันดูเหมือนกัน ที่นี่ lspci ตอนไม่มี HAT โชว์แค่ชิปของพายเอง พอใส่ HAT ก็มีบรรทัดใหม่โผล่มาหนึ่งบรรทัด บรรทัดเดียวนั้นคือหลักฐาน先开一块光秃秃的树莓派。如果第一次开机就装着 HAT,结果什么都不动,你分不清是卡坏了还是排线松了,看起来一模一样。这里没装 HAT 时,lspci 只显示树莓派自己的芯片。装上 HAT 后多了一行。那一行就是证据。

TWO FAILS AFTER THE INSTALL ARE GOOD NEWSThe preflight script checks a Pi before you install. Run it again afterwards and two checks fail. Port 8000 is taken, by hailo-ollama, which is exactly what should be there now. And the disk has less room, because the models are on it. Read what a FAIL says before you fix it.สคริปต์ตรวจก่อนบินใช้ตรวจพายก่อนติดตั้ง ถ้ารันอีกครั้งหลังติดตั้ง จะมีสองข้อที่ไม่ผ่าน พอร์ต 8000 ถูกใช้แล้วโดย hailo-ollama ซึ่งเป็นสิ่งที่ควรอยู่ตรงนั้นพอดี และดิสก์มีที่ว่างน้อยลง เพราะมีโมเดลอยู่ในนั้นแล้ว อ่านว่า FAIL บอกอะไรก่อนจะไปแก้起飞前检查脚本是在安装之前检查树莓派的。装完再跑一次,会有两项不过:8000 端口被 hailo-ollama 占了,而它现在本来就该在那儿;磁盘空间变少了,因为模型已经在上面。修 FAIL 之前,先读它说了什么。
TWO THINGS IMAGER DID NOT DOImager 2.0 was given a hostname and an SSH key. The card came out with the hostname mypi and no key. Both settings live in a text file called user-data on the card's small partition. It was fixed there, before the first boot. Imager also did not give the user password-free sudo, so installing anything asked for a password over SSH. Open the card and read user-data before you boot.Imager 2.0 ได้รับชื่อเครื่องและคีย์ SSH ไปแล้ว แต่การ์ดออกมาพร้อมชื่อ mypi และไม่มีคีย์ ทั้งสองค่าอยู่ในไฟล์ข้อความชื่อ user-data บนพาร์ทิชันเล็กของการ์ด แก้ที่นั่นก่อนบูตครั้งแรก Imager ยังไม่ได้ให้ sudo แบบไม่ต้องใส่รหัสผ่าน การติดตั้งอะไรผ่าน SSH จึงถามรหัสผ่าน ให้เปิดการ์ดอ่าน user-data ก่อนบูต给了 Imager 2.0 主机名和 SSH 密钥,卡出来却叫 mypi,而且没有密钥。这两个设置都在卡的小分区上一个叫 user-data 的文本文件里,第一次开机前在那里改好了。Imager 也没给用户免密码的 sudo,所以通过 SSH 装东西会要密码。开机前,先打开卡读一下 user-data。
这叫 mDNS,多播 DNS。Windows、Mac、iPhone 和 Linux 都会。有些 Android 手机不会,那就直接输入树莓派的数字地址。

IT ONLY WORKS ON THE SAME WI-FIThe shout does not go past your router. A phone on mobile data cannot find pihat.local. Neither can a friend in another house. That is also why this chatbot is private: nobody outside your Wi-Fi can reach it. Unless you share it on purpose: section 32 does that with Tailscale.เสียงตะโกนไม่ออกไปเกินเราเตอร์ของคุณ มือถือที่ใช้เน็ตมือถือหา pihat.local ไม่เจอ เพื่อนที่อยู่อีกบ้านก็หาไม่เจอ นี่คือเหตุผลเดียวกับที่แชตบอตนี้เป็นส่วนตัว คนนอก Wi-Fi ของคุณเข้าไม่ถึง เว้นแต่คุณจะตั้งใจแชร์มัน: ส่วนที่ 32 ทำแบบนั้นด้วย Tailscale这一声喊不会越过你的路由器。用手机流量的手机找不到 pihat.local,别人家的朋友也找不到。这也是这个聊天机器人私密的原因:你 Wi-Fi 以外的人碰不到它。除非你有意分享它:第 32 节用 Tailscale 做到这一点。
IN A CAFÉ, EXPECT IT TO FAILCafé Wi-Fi usually stops customers' devices from seeing each other. This is called client isolation, and it protects your laptop from strangers. It also stops the shout, and even the Pi's number. The Pi also only knows your home Wi-Fi, and cannot click a café's "accept" page. Two things do work. Put the Pi and your laptop on your phone's hotspot, which you control. Or install Tailscale on both, and reach the Pi from anywhere with internet.Wi-Fi ในร้านกาแฟมักไม่ให้อุปกรณ์ของลูกค้ามองเห็นกัน เรียกว่า client isolation ซึ่งปกป้องแล็ปท็อปของคุณจากคนแปลกหน้า แต่มันก็หยุดเสียงตะโกน และหยุดแม้แต่หมายเลขของพาย พายเองก็รู้จักแค่ Wi-Fi ที่บ้าน และกดหน้า "ยอมรับ" ของร้านไม่ได้ มีสองทางที่ใช้ได้ ให้พายกับแล็ปท็อปใช้ฮอตสปอตจากมือถือของคุณ ซึ่งคุณควบคุมเอง หรือติดตั้ง Tailscale ทั้งสองเครื่อง แล้วเข้าถึงพายได้จากทุกที่ที่มีอินเทอร์เน็ต咖啡馆的 Wi-Fi 通常不让顾客的设备互相看见,这叫客户端隔离(client isolation),它保护你的电脑不被陌生人碰。可它也挡住了那一声喊,连树莓派的数字地址也挡住。树莓派还只认识你家的 Wi-Fi,也点不了咖啡馆的"同意"页面。有两个办法可行:让树莓派和电脑都连你手机的热点,那是你自己控制的;或者两台都装 Tailscale,有网络的地方就能连到树莓派。

ALWAYS RUN VISUDO -CA sudoers file with one typing mistake can stop sudo working for everyone, the teacher too. visudo -c reads the file and says parsed OK or tells you the line. Check before you log out.ไฟล์ sudoers ที่พิมพ์ผิดแค่ที่เดียวอาจทำให้ sudo ใช้ไม่ได้สำหรับทุกคน รวมถึงครูด้วย visudo -c อ่านไฟล์แล้วบอกว่า parsed OK หรือบอกบรรทัดที่ผิด ตรวจก่อนออกจากระบบsudoers 文件只要打错一处,就可能让所有人都用不了 sudo,老师也不例外。visudo -c 会读这个文件,说 parsed OK,或者告诉你哪一行错了。退出登录前先检查。

HOW A UNIT FILE IS INSTALLED, AND WHAT RESTART=ON-FAILURE DOESCopy the file into /etc/systemd/system/, daemon-reload, then enable --now: it starts, and it is booked for every boot. The run below is from 28 September, when the chatbot's service was first made; the same three commands installed the other five. Then a crash on purpose, to see the restart.คัดลอกไฟล์ไปที่ /etc/systemd/system/ แล้ว daemon-reload แล้ว enable --now: มันเริ่มทำงาน และถูกจองไว้ให้เริ่มทุกครั้งที่บูต การรันข้างล่างเป็นของวันที่ 28 กันยายน ตอนสร้างบริการของแชตบอตครั้งแรก สามคำสั่งเดียวกันติดตั้งอีกห้าบริการที่เหลือ แล้วทำให้พังโดยตั้งใจ เพื่อดูการเริ่มใหม่把文件拷进 /etc/systemd/system/,daemon-reload,再 enable --now:它启动了,而且每次开机都会启动。下面的记录来自 9 月 28 日第一次做聊天机器人服务的时候;另外五个服务也是同样三条命令装的。然后故意让它崩溃一次,看它重启。
✅ RAN ON THE PI · install it, in the folder that holds the file

sudo systemctl daemon-reload
# enable: start it at every boot. --now: and start it now, too.
sudo systemctl enable --now web-factory
WHY RESTART=ON-FAILURE MATTERS AT BOOTAs it starts, the chatbot asks Bitkub for its list of coins. At boot, the Wi-Fi is sometimes not ready yet, so that call fails and the program stops. Restart=on-failure waits 10 seconds and tries again. After a real reboot here, the page answered 73 seconds after the Pi went down.ตอนเริ่ม แชตบอตจะขอรายชื่อเหรียญจาก Bitkub ตอนบูต บางครั้ง Wi-Fi ยังไม่พร้อม การเรียกนั้นจึงล้มเหลวและโปรแกรมหยุด Restart=on-failure จะรอ 10 วินาทีแล้วลองใหม่ หลังรีบูตจริงที่นี่ หน้าเว็บตอบได้ 73 วินาทีหลังจากพายดับไป启动时,聊天机器人会向 Bitkub 要币种列表。开机时 Wi-Fi 有时还没好,这个请求就会失败,程序就停了。Restart=on-failure 会等 10 秒再试。这里真的重启一次后,树莓派关掉 73 秒后网页就能回答了。

🇬🇧 English
The Pi has no fan. Idle, it sits at 46 to 55 °C. Biscuit on the HAT hardly warms it: the HAT does the work, and its own chip measured 48 to 62 °C. ✨ Auto is different: it runs a 3B model on the Pi's four cores, and two questions in a row take the processor from 55 to 72–82 °C. The Pi 5 slows itself at 80 °C.
Three things watch that. The chatbot reads the temperature before every ✨ Auto question and, at 80 or over, answers "Ruh-roh! My processor is hot" from Python, runs no model, and lets the buttons carry on: HOT and degrees() below. The heat guard, a systemd timer, reads the processor and the HAT every 5 minutes, three times 5 seconds apart, and books a shutdown if all three readings are over 80 (processor) or 85 (HAT): a spike does not count. And the temperature file itself is readable by anyone: the student account cannot run vcgencmd, which needs the video group, so the log below reads the file instead.
On 30 September the Pi went down twice, each time during or just after a run of ✨ Auto questions, and the first time it was found switched off. The heat guard is the one thing on it that switches it off, and the run of the second time, in section 28, shows the processor at 72 to 75 °C between questions. But there is no proof: Raspberry Pi OS keeps the journal in memory, to spare the card, so the log of those minutes went with the power. The last run below changes that: one file in /etc/systemd/journald.conf.d/, and the journal now lives on the card, so the next shutdown will have its line. That is the honest state of this Pi without a fan. The official Active Cooler fits under the AI HAT+ 2 and keeps a Pi 5 near 60 °C under this load.

树莓派没有风扇。空闲时在 46 到 55 °C。HAT 上的 Biscuit 几乎不让它发热:活是 HAT 干的,它自己的芯片测到 48 到 62 °C。✨ Auto 不一样:它在树莓派的四个核上跑一个 3B 模型,连着两个问题就把处理器从 55 推到 72–82 °C。树莓派 5 在 80 °C 会自己降速。
有三样东西盯着这件事。聊天机器人在每个 ✨ Auto 问题之前读一次温度,到了 80 或以上,就由 Python 回答“哎呀!我的处理器好热”,不跑任何模型,让其他按钮继续工作:见下面的 HOT 和 degrees()。热保护是一个 systemd 定时器,每 5 分钟读处理器和 HAT 各三次、间隔 5 秒,三次都超过 80(处理器)或 85(HAT)才预约关机:一瞬间的尖峰不算。温度文件本身谁都能读:学生账号跑不了 vcgencmd,那需要 video 组,所以下面的日志直接读文件。
9 月 30 日树莓派掉了两次,每次都在一连串 ✨ Auto 问题期间或刚结束之后,第一次被发现时已经是关机状态。热保护是它身上唯一会关机的东西,第二次的运行记录在第 28 节,问题之间处理器在 72 到 75 °C。但没有证据:Raspberry Pi OS 为了保护卡,把 journal 放在内存里,那几分钟的日志随断电一起没了。下面最后一段运行改变了这一点:/etc/systemd/journald.conf.d/ 里加一个文件,journal 就存在卡上了,下一次关机会留下它的那一行。这就是这块没有风扇的树莓派的真实状态。官方的 Active Cooler 能装在 AI HAT+ 2 下面,在这种负载下能让树莓派 5 保持在 60 °C 左右。

A HEAT GUARDA systemd timer checks the Pi every 5 minutes. It reads the CPU and the HAT's own chip three times, 5 seconds apart. If all three readings of one of them are over its limit, 80 °C for the CPU or 85 °C for the HAT, it books a shutdown one minute later and tells everyone logged in. A spike does not count. The Pi 5 starts slowing itself down at 80 °C, so staying there means the cooling is not keeping up. No published limit was found for the Hailo-10H, so 85 °C is a cautious guess. Here the CPU sat at about 51 °C, and the HAT at 48 °C, or 61 °C while answering.ตัวจับเวลาของ systemd ตรวจพายทุก 5 นาที มันอ่าน CPU และชิปของ HAT สามครั้ง ห่างกัน 5 วินาที ถ้าค่าทั้งสามของตัวใดตัวหนึ่งเกินขีด คือ 80 °C สำหรับ CPU หรือ 85 °C สำหรับ HAT มันจะสั่งปิดเครื่องในอีกหนึ่งนาที และแจ้งทุกคนที่เข้าสู่ระบบอยู่ ค่าที่พุ่งขึ้นชั่วครู่ไม่นับ พาย 5 เริ่มลดความเร็วตัวเองที่ 80 °C ถ้าค้างอยู่ตรงนั้นแปลว่าการระบายความร้อนตามไม่ทัน ไม่พบขีดจำกัดที่เผยแพร่ของ Hailo-10H 85 °C จึงเป็นการเดาอย่างระมัดระวัง ที่นี่ CPU อยู่ราว 51 °C และ HAT 48 °C หรือ 61 °C ตอนกำลังตอบ一个 systemd 定时器每 5 分钟检查一次树莓派。它读 CPU 和 HAT 自己芯片的温度三次,每次隔 5 秒。如果其中一个的三次读数都超过上限,CPU 是 80 °C,HAT 是 85 °C,它就安排一分钟后关机,并通知所有登录的人。一下子冲高不算。树莓派 5 到 80 °C 就开始给自己降速,一直停在那里说明散热跟不上。没找到 Hailo-10H 公布的上限,所以 85 °C 是一个谨慎的估计。这里 CPU 大约 51 °C,HAT 48 °C,回答问题时 61 °C。

🇬🇧 English
Two programs answer model requests on this Pi. hailo-ollama, from Hailo, runs models on the HAT's chip: fast, and the only way onto that chip. It copies most of Ollama's API and lacks two things the chatbot needs, a Modelfile and tool calling. Real Ollama runs beside it on the Pi's processor: slow, with the whole API. Biscuit lives on the first; ✨ Auto's agent on the second.

WHY THE AGENT'S MODEL IS NOT ON THE HATAn agent needs a model that chooses a tool. Ollama's own way, a tools field in the request, gets a 500 from this server. The other way, ReAct, is plain text and needs nothing from the server, but the 1.5B model on the HAT chose the right tool 33 times in 112 and mostly ignored the tools: section 27. So the agent's model runs in real Ollama on the processor, section 14, and Biscuit stays on the HAT to write.เอเจนต์ต้องการโมเดลที่เลือกเครื่องมือ วิธีของ Ollama เอง คือฟิลด์ tools ในคำขอ ได้ 500 จากเซิร์ฟเวอร์นี้ อีกวิธี ReAct เป็นข้อความธรรมดาและไม่ต้องการอะไรจากเซิร์ฟเวอร์ แต่โมเดล 1.5B บน HAT เลือกเครื่องมือถูก 33 ใน 112 และส่วนใหญ่ไม่สนใจเครื่องมือเลย: ส่วนที่ 27 โมเดลของเอเจนต์จึงรันใน Ollama ตัวจริงบนตัวประมวลผล ส่วนที่ 14 และบิสกิตอยู่บน HAT เพื่อเขียน智能体需要一个会选工具的模型。Ollama 自己的办法,请求里的 tools 字段,在这个服务器上得到 500。另一个办法 ReAct 是纯文本,对服务器没有要求,可是 HAT 上的 1.5B 模型 112 次里只选对 33 次,多数时候根本不用工具:见第 27 节。所以智能体的模型跑在处理器上真正的 Ollama 里,第 14 节,Biscuit 留在 HAT 上负责写。
12Who Biscuit is, the Modelfile way · บิสกิตเป็นใคร แบบ Modelfile · Biscuit 是谁:Modelfile 的方式
🇬🇧 English
On a PC, an identity is a Modelfile: FROM, PARAMETER, SYSTEM, and ollama create. The HAT's server has no create: POST /api/create answers 404, and Hailo's documentation lists no such thing. But every model there has a manifest, a small file with its sampling settings in it, a system_prompt field, and its chat template.
Measured. The system_prompt field is dead: the server never reads it, and a model made with it still said "I'm Qwen". The sampling settings work: temperature 0 gave the same words three times. And the chat template carries the model's default identity, "You are Qwen, created by Alibaba Cloud". Put Biscuit's words there, restart the server, and the model answers as Biscuit with no system message sent. A system message in a request still wins, as in Ollama.
So make_biscuit.py is the Modelfile, in Python. It copies a manifest, writes Biscuit's words into the template, sets the temperature, and makes two models: biscuit, and biscuit-th from the older Qwen 2 that writes better Thai. Then sudo systemctl restart hailo-ollama. The chatbot sends no system message any more.
The identity is three sentences: a name and a manner. Everything else Biscuit knows moved to a file, in section 26, because a long identity made the model forget the chat.

测量。system_prompt 字段是死的:服务器从不读它,用它做出来的模型还是说"我是 Qwen"。采样设置有效:温度 0 三次给出一模一样的话。而聊天模板里带着模型的默认身份,"You are Qwen, created by Alibaba Cloud"。把 Biscuit 的话写到那里,重启服务器,模型不用发 system message 也会以 Biscuit 的身份回答。请求里自带的 system message 仍然优先,和 Ollama 一样。

13Use the HAT from a Mac: an Ollama relay · ใช้ HAT จาก Mac: ตัวส่งต่อ Ollama · 从 Mac 使用 HAT:一个 Ollama 中转
🇬🇧 English
The HAT's model server, hailo-ollama, answers the whole network on port 8000, and it speaks Ollama's language. So a laptop on the same Wi-Fi can already use it with curl, or with plain HTTP from Python. But the everyday Ollama tools fell over, each on a small difference:
The ollama command first checks that / says "Ollama is running". hailo-ollama answers "not found" there, so the command stopped with "something went wrong".
The ollama Python library always sends "tools": [], and hailo-ollama crashes on the empty list.
ollama list needs a digest, an ID, for each model, and got none. ollama run asks for the model's details and got model_info as text, not an object.
ollama_relay.py listens on Ollama's own port, 11434, passes every request on to port 8000, and smooths over those four things. It is a systemd service with a throwaway user of its own. On the Mac, one setting: OLLAMA_HOST=http://pihat.local:11434. Then ollama list, ollama run and the Python library all worked, streaming too.
What it cannot do is tool calling, where the model picks a tool and sends back a structured call. That is what an agent library expects from a server. Any request with a tool in it gets an error from hailo-ollama, straight or through the relay. The relay mends the shape of requests; it cannot give the server a feature it does not have. That is why ✨ Auto's agent runs on real Ollama instead, on the processor: section 14.
ollama list 需要每个模型的 digest(编号),却拿不到。ollama run 要模型的详情,拿到的 model_info 是文字,不是对象。
ollama_relay.py 在 Ollama 自己的端口 11434 上听,把每个请求转给 8000 端口,并把这四件事抹平。它是一个 systemd 服务,有自己专用的临时用户。在 Mac 上只要设一项:OLLAMA_HOST=http://pihat.local:11434。之后 ollama list、ollama run 和 Python 库全都能用,流式输出也行。
它做不到的是工具调用:由模型挑一个工具,并送回一个结构化的调用。智能体库对服务器要求的正是这个。任何带工具的请求,不管直接发还是经过中转,hailo-ollama 都回一个错误。中转修的是请求的形状,给不了服务器本来没有的功能。这就是 ✨ Auto 的智能体改在处理器上真正的 Ollama 里运行的原因:见第 14 节。

14Real Ollama, on the processor · Ollama ตัวจริง บนตัวประมวลผล · 真正的 Ollama,在处理器上
🇬🇧 English
Ollama itself runs on a Pi 5, on its processor, not on the HAT. The download is 1.55 GB and 48 MB of it is kept: the rest is CUDA libraries, for other computers. It runs as a service on port 11435, and the HAT's relay keeps 11434. Its speed, with ReAct's 780-token instructions in front of the question: Hermes 8B took 114 s for the first call, 56 of them loading, then 21 to 27 s a step, and 6 GB of memory. Qwen 2.5 3B took 63 s, then 8 s a step, and 3 GB. So Qwen 2.5 3B.
WHAT IT IS FOR, AND WHAT IT COSTSReal Ollama is here for one thing: ✨ Auto's agent, section 28, which needs tool choice the HAT's server cannot give. It runs as the service ollama-cpu, section 8, as the student, with its models in ~/ollama/models. The cost is the processor: the 3B model takes about 3 GB of memory and all four cores, and section 10 says what that does to the temperature. You can use it yourself too: section 15.Ollama ตัวจริงอยู่ที่นี่เพื่อสิ่งเดียว: เอเจนต์ของ ✨ Auto ส่วนที่ 28 ซึ่งต้องการการเลือกเครื่องมือที่เซิร์ฟเวอร์ของ HAT ให้ไม่ได้ มันรันเป็นบริการ ollama-cpuส่วนที่ 8 ในนามนักเรียน โดยมีโมเดลอยู่ใน ~/ollama/models ราคาที่ต้องจ่ายคือตัวประมวลผล: โมเดล 3B ใช้หน่วยความจำราว 3 GB และทั้งสี่คอร์ และส่วนที่ 10 บอกว่านั่นทำอะไรกับอุณหภูมิ คุณใช้มันเองได้ด้วย: ส่วนที่ 15真正的 Ollama 在这里只为一件事:✨ Auto 的智能体,第 28 节,它需要 HAT 的服务器给不了的选工具能力。它作为服务 ollama-cpu 运行,第 8 节,以学生身份,模型放在 ~/ollama/models。代价是处理器:3B 模型占大约 3 GB 内存和全部四个核,第 10 节说了这对温度意味着什么。你自己也能用它:第 15 节。

15Use Ollama on the Pi yourself · ใช้ Ollama บนพายด้วยตัวเอง · 自己在树莓派上用 Ollama
🇬🇧 English
Real Ollama is on the Pi for the agent, but it is yours to use too, like Ollama on a PC. Two things are different. Its program is in ~/ollama/bin, not on the path, and it answers on port 11435, not the usual 11434, because the HAT's relay has that one. One line in ~/.bashrc settles both, and then ollama list, ollama run and ollama pull work as they do anywhere.
From Python, the ollama library is in the chatbot's venv already: ollama.Client(host="http://localhost:11435"), then client.chat(...). From a Mac or a PC on the same Wi-Fi, OLLAMA_HOST=http://pihat.local:11435 in front of any ollama command. Port 11434 gives you Biscuit's model on the HAT instead, as in section 13.
Mind the card: about 4 GB is free, and a 3B model is 2 GB. ollama rm gives the space back. And mind the heat: a model on the processor warms the Pi as section 10 says, and the agent shares the same processor.
# Real Ollama on the Pi answers on port 11435, not Ollama's usual 11434,# and its program is in ~/ollama/bin. One line in ~/.bashrc makes the# ordinary `ollama` commands work. Log out and in again after adding it.

One file, web_factory.py, about 2,000 lines, is the whole chatbot: the two web pages as strings, the tools, the memory, the agent, the factory and main(). This part shows the whole file once, then reads it a piece at a time. Every excerpt below is cut from the file that runs on the Pi, by a script, so the page cannot drift from it; every transcript is what the Pi answered.

🇬🇧 English
Read it in this order. The settings at the top: the two model servers and their models, the six buttons, the puppy's words. Then the two pages, FORM_PAGE and CHAT_PAGE, which are HTML and JavaScript inside Python strings. Then the tools: coin_price, make_map, web_search, make_page. Then what runs them: lookup() for a button, converse() for a chat, auto() for the agent, and answer(), which reads the button and chooses between them. Then the factory, page_class() and handler_class(), and main(), which builds everything and starts the web server. The sections after this one take those pieces one at a time.
Normally the service starts it, section 8. Started by hand instead, as the student, it prints what it is doing, and the same lines go to the journal when the service runs it. Then, on any phone or laptop on the same Wi-Fi, open http://pihat.local:8080, type your name, and ask. The grey lines under each question show what happened: who chose, which tool ran, what it found.

The router gave the Pi its address, and told it two things: send everything outside the house to me, and ask me to look up names. So a price comes from Bitkub through your router. Maps have a surprise. The Pi only finds the place and writes a small page. The map pictures come from OpenStreetMap to your browser, not through the Pi. So the phone you use needs internet too.ผ่านเราเตอร์ Wi-Fi ของคุณ เหมือนอุปกรณ์อื่นทุกเครื่องในบ้าน เราเตอร์ให้ที่อยู่กับพาย และบอกสองเรื่อง ส่งทุกอย่างที่อยู่นอกบ้านมาที่ฉัน และให้ถามฉันเมื่อต้องค้นหาชื่อ ราคาจึงมาจาก Bitkub ผ่านเราเตอร์ของคุณ แต่แผนที่มีเรื่องน่าแปลกใจ พายแค่หาสถานที่และเขียนหน้าเว็บเล็ก ๆ ส่วนภาพแผนที่มาจาก OpenStreetMap ตรงไปที่เบราว์เซอร์ของคุณ ไม่ได้ผ่านพาย มือถือที่คุณใช้จึงต้องมีอินเทอร์เน็ตด้วย通过你的 Wi-Fi 路由器,和家里其他设备一样。路由器给了树莓派地址,还告诉它两件事:家外面的东西都交给我;查名字来问我。所以价格是经过你的路由器从 Bitkub 来的。地图有个意外:树莓派只负责找地点、写一个小网页,地图图片是从 OpenStreetMap 直接到你的浏览器,不经过树莓派。所以你用的手机也要能上网。

YOUR TURN
Find the six buttons in CHAT_PAGE, then find the same six names in BUTTONS near the top. One place makes the row on the page; the other decides what a press does.
Open the page on two phones and ask at the same time. Watch the second one wait for the Lock.
Start it by hand, as above, and ask one question. Then read the journal with the service running: journalctl -u web-factory -f. Same lines.
17The web server: tkinter against the web, and type() twice · เว็บเซิร์ฟเวอร์: tkinter เทียบกับเว็บ และ type() สองครั้ง · 网页服务器:tkinter 对比网页,以及两次 type()
🇬🇧 English
Almost every part of window_factory.py has a web twin. Two things are really different, and both are about time.
First, a web page forgets. The tkinter form was an object that stayed alive, so main() could read the name after the window closed. A web page has no such object. So the name travels in the address: /chat?user_name=Nari.
Second, the waiting. tkinter needed a thread, a queue and after(), because only one thread may touch a window. The web server gives every visitor their own thread already. Here the danger is the other way round: two visitors at once. A Lock makes them take turns, because the HAT works on one question at a time.
第二,等待。tkinter 需要线程、队列和 after(),因为只有一个线程能碰窗口。网页服务器本来就给每个访客一个自己的线程。这里的危险反过来了:两个访客同时来。一把 Lock 让他们排队,因为 HAT 一次只处理一个问题。

THE NAME STAYS ON THE PAGE, NOT IN THE MODELOn the classes page, telling the model your name made it use the name. On the HAT it went wrong. Asked "Who invented Bitcoin?" with the name in the prompt, it answered "Nari invented Bitcoin." So here the name is only shown on the page, next to what you typed. The model never sees it.ในหน้าคลาส การบอกชื่อให้โมเดลทำให้มันเรียกชื่อคุณ แต่บน HAT มันผิดพลาด พอถามว่า "Who invented Bitcoin?" โดยมีชื่ออยู่ในพรอมต์ มันตอบว่า "Nari invented Bitcoin." ที่นี่ชื่อจึงแสดงแค่บนหน้าเว็บ ข้าง ๆ สิ่งที่คุณพิมพ์ โมเดลไม่เคยเห็นชื่อเลย在类那一页,把名字告诉模型会让它用上名字。在 HAT 上却出了错:提示词里有名字时问 "Who invented Bitcoin?",它回答 "Nari invented Bitcoin."。所以这里名字只显示在网页上,放在你打的字旁边。模型根本看不到。
TYPE(), TWICEtype() takes three things: a name, the parents, and a dict of methods. This file calls it twice. The two pages need no parent: they are ours. The handler must have one, because Python's web server only calls a handler built on its own. Both calls, and main(), which builds everything and starts the servers, are below.type() รับสามอย่าง: ชื่อ คลาสแม่ และดิกต์ของเมธอด ไฟล์นี้เรียกมันสองครั้ง หน้าเว็บสองหน้าไม่ต้องมีคลาสแม่: เป็นของเราเอง ส่วน handler ต้องมี เพราะเว็บเซิร์ฟเวอร์ของ Python เรียกได้แต่ handler ที่สร้างต่อจากของมันเอง ทั้งสองการเรียก และ main() ที่สร้างทุกอย่างและเริ่มเซิร์ฟเวอร์ อยู่ข้างล่างtype() 要三样东西:名字、父类、方法字典。这个文件调用了它两次。两个页面不需要父类:它们是我们自己的。handler 必须有,因为 Python 的网页服务器只调用建立在它自己那个之上的 handler。两次调用,以及造出一切并启动服务器的 main(),都在下面。

18Six buttons: two conversations, three lookups, and ✨ Auto · หกปุ่ม: สองบทสนทนา สามการค้นหา และ ✨ Auto · 六个按钮:两个对话,三种查询,和 ✨ Auto
🇬🇧 English
The row above the typing box decides what a message means, and nothing is guessed. 💬 Chat and 🌐 Page are conversations: the model reads everything said before in that conversation, section 19. 💰 Price, 🗺️ Map and 🔎 Search look one thing up, on what was typed and nothing else; what they find is added to the chat's memory, so a chat can carry on from it. ✨ Auto hands the message to the agent, section 28, which chooses among the same tools itself. The pressed button stays pressed until another is pressed.
answer() is the whole decision, and lookup() runs one tool for a button. Python still has to find which coin or place was typed, and the button removes the guess about which tool. Below them, a real session through the chatbot today: one browser, every button, in three languages. Read the last 💬 Chat answers too: the 1.5B model on the HAT got the Chinese memory right and the English one wrong, which is about its average.

19The memory: a list of messages, one per browser · ความจำ: ลิสต์ของข้อความ หนึ่งชุดต่อเบราว์เซอร์ · 记忆:一份消息列表,每个浏览器一份
🇬🇧 English
The documented way. A model remembers nothing. Ollama's documentation keeps a chat as a list of messages, sent again with every question, and that list is the whole memory. 💬 Chat and 🌐 Page are conversations, each with a list of its own per browser. 💰 Price, 🗺️ Map and 🔎 Search look one thing up, on what was typed, and what they find is added to the chat's list.
Measured. Three ways of handing the chat back to the model, 6 conversations, 4 tries each: pasted into one message, 11 of 24; real messages, 15; real messages that keep what was looked up, 19. A lower temperature did not help: 12, 13, 10 and 10 of 25. The persona did. With the full persona, the model recalled a fact from two or three turns back 2 times in 16. Without the sentence about Eva and Charlie, 8. With a one-line persona, 9. It mixes up its own friends with the person: "I'm sorry, I don't have a cat."
Honest. In the real chatbot, before and after, it recalled a fact from three turns back 3 times in 8. This 1.5B model gets about half of them, whatever the prompt.

20💰 Price: Bitkub's own line · 💰 Price: บรรทัดของ Bitkub เอง · 💰 Price:Bitkub 自己的那一行
🇬🇧 English
Bitkub is a Thai exchange with a public price list, in baht, and no key. coin_price asks it for one ticker and hands back one line: the price, and how it moved in 24 hours. Python finds the ticker in what was typed: NAMES for English words like bitcoin and doge, COIN_NAMES for Thai and Chinese, which have no spaces between words, and capital letters for a bare ticker like BTC. With 💰 pressed, one word is enough. A whole Thai sentence must not be sent as a ticker: only Latin letters can be one.
The reply is Bitkub's line as it came, with a puppy's words in front: 🤩 if the coin is up, 💪 if it is down. The small model is not asked to repeat the number, because when it was, it sometimes dropped it, and once added a dollar price it made up. On ✨ Auto the agent calls the same tool and writes its own sentence from the line; section 28 shows what that did.
回答就是 Bitkub 原样的那一行,前面加一句小狗的话:币涨了是 🤩,跌了是 💪。不让小模型重复数字,因为以前让它重复时,它有时会把数字丢掉,有一次还加了一个编出来的美元价格。在 ✨ Auto 上,智能体调用同一个工具,再根据那一行自己写一句话;第 28 节展示了结果。

🇬🇧 English
OpenStreetMap's search, Nominatim, finds names, not sentences. "Show me a map of Chiang Mai and mark important places" finds nothing. So Python looks at the words before OpenStreetMap does. A place name with more than three spaces is too long, so the model on the HAT is asked for the short form, and its answer is checked: it must be words the person really typed. The first version trusted it, and the model turned Chiang Mai into Chiang Rai, a different city. If the model's answer fails the check, Python takes the longest run of Capitalised Words instead. In the test below, that is what found both Chiang Mai and the Three Kings Monument.
With 🗺️ Map pressed, a second row of buttons appears. Each one is something Nominatim or the map picture already accepts. Labels: Locals is the usual OpenStreetMap picture, with every country in its own language, Thai in Thailand. Locals + English comes from the German OpenStreetMap server, which adds the English name where one is known. Both are free, with no key. A map with English only needs a paid key, from MapTiler for example. Names is the language of the place names in the answer. Thailand only, Places (how many to pin) and Outline (the border) go straight to the search.
📍 Here is a switch. On, it asks the browser where you are, and the Pi turns the numbers into an address and draws a blue circle as wide as the browser's accuracy. A browser only tells a secure page where you are, so on the plain http page, pressing 🗺️ Map moves to the Pi's https page. Section 32 gives it a certificate every browser trusts. Typing here, my location, ที่นี่ or 这里 does the same as the button.

OpenStreetMap 的搜索叫 Nominatim,它找的是名字,不是句子。"Show me a map of Chiang Mai and mark important places" 什么都找不到。所以 Python 先看这些词,再交给 OpenStreetMap。超过三个空格的地名太长了,就让 HAT 上的模型给出简短的名字,而且要核对它的答案:必须是这个人真的打出来的词。第一版直接相信了它,结果模型把清迈变成了清莱,另一个城市。如果模型的答案没通过核对,Python 就取最长的一串首字母大写的词。下面的测试里,清迈和三王纪念碑都是这样找到的。

22🔎 Search: DuckDuckGo, four pages, and the links · 🔎 Search: DuckDuckGo สี่หน้า และลิงก์ · 🔎 Search:DuckDuckGo、四个网页,和链接
🇬🇧 English
A web search knows today: the air quality, the news, tomorrow's weather. DuckDuckGo needs no key and no account. The ddgs library asks it and hands back the first four pages, each with a title, an address and a snippet, a few lines cut from the page. web_search writes them as one line per page. Biscuit on the HAT then writes the answer from the titles and snippets only: handed the numbers and addresses too, it copied them into its answer. The chat lists the four pages as links under the answer, so the answer can be checked.
Two things Python does to the answer. If the message asks for a link or a video, Python writes the reply and the links speak for themselves: the model used to invent "our YouTube channel". And a refusal, "I can't provide scores", which this small model says even with fresh results in front of it, is replaced by what the search really found. On ✨ Auto the agent decides when to search, and writes the answer itself.
网页搜索知道今天的事:空气质量、新闻、明天的天气。DuckDuckGo 不需要密钥,也不需要账号。ddgs 库去问它,拿回前四个网页,每个有标题、地址和摘要,也就是从网页上截下来的几行。web_search 把它们写成每页一行。然后 HAT 上的 Biscuit 只根据标题和摘要写答案:连编号和地址也给它的话,它会照抄进答案。聊天页面把四个网页列成链接放在答案下面,方便核对。
Python 对答案做两件事。如果消息要的是链接或视频,就由 Python 写回复,链接自己说话:模型以前会编出“我们的 YouTube 频道”。而“我不能提供比分”这类拒绝,这个小模型即使眼前就有新鲜的结果也会说,会被换成搜索真正找到的内容。在 ✨ Auto 上,由智能体决定什么时候搜索,答案也由它自己写。

🇬🇧 English
Writing a small web page is something language models are good at. Describe it, "a tip calculator in baht", and a minute later there is a page that works. The new tool, make_page, asks the model for one whole HTML file, saves it in ~/web-factory/pages/, and the chat shows it running. Under it: ⬇ Download saves the file to your own computer, 🔗 Open opens it in its own tab, and </> Code shows the HTML in the chat, to read or copy.
Not the chat model, though. Asked for a birthday card, qwen2.5-instruct started a comment with <!-- and never closed it, so the button vanished, and it wrote its JavaScript as text on the page. The HAT's own list has qwen2.5-coder:1.5b: the same size, trained on code. Asked the same thing, it wrote a page with a style, a button and a script. So pages use that one: PAGE_MODEL, near the top.
Two things the coder model does that Python fixes. It wraps the page in ```html fences, and html_from() cuts the page out. And a page saved to a computer has only its own <meta charset="utf-8"> line to say it is UTF-8. Without it, Thai turns to nonsense, so Python adds it if the model left it out.
The HAT holds one model at a time. Switching from one to the other took 14 to 18 seconds, so the first page after chatting, and the first chat after a page, waits that much longer. A page took 25 to 90 seconds.

IT LOOKS RIGHT, THE FACTS MAY NOT BEThe coder model writes code, not facts. On a page about Doi Suthep it made up "three main gates", and on a fruit page it gave องค์ฟ้า as Thai for orange (it is ส้ม). Check every word before you share a page.โมเดลโค้ดเขียนโค้ด ไม่ได้เขียนข้อเท็จจริง ในหน้าเกี่ยวกับดอยสุเทพ มันแต่งเรื่อง "ประตูหลักสามประตู" และในหน้าผลไม้ มันบอกว่า orange ภาษาไทยคือ องค์ฟ้า (ที่จริงคือ ส้ม) ตรวจทุกคำก่อนแชร์หน้าเว็บ代码模型写的是代码,不是事实。在一个关于素贴山的网页上,它编出了"三座主门";在一个水果网页上,它说橙子的泰语是 องค์ฟ้า(其实是 ส้ม)。分享网页之前,每个字都要核对。
24🐶 Biscuit's moods, and the words Python writes · 🐶 อารมณ์ของบิสกิต และคำที่ Python เขียน · 🐶 Biscuit 的心情,和 Python 写的话
🇬🇧 English
The chatbot is Biscuit, a cheerful cartoon puppy. Its name and manner are inside the two biscuit models on the HAT, section 12, and everything else it knows is in biscuit.md, section 26. So web_factory.py sends no system prompt at all. What it does add is below: a name for the page, fourteen things the puppy can be doing while the Pi works, and a mood for every answer.
Each answer gets a mood, and Python picks it from what happened. No model is asked, so it is never wrong. All seven are cheerful: 😊 happy, 🤩 excited (a map, or a price going up), 🧐 curious (a search), 🥳 proud (a finished web page), 💪 cheering (a price going down), 🥰 loving (thanks, love or Peppa), and 🙈 oops. The page shows a 🐶 with the mood's badge, and it bounces, tilts, nods or wiggles to match. While the Pi works, a 🤔 puppy does one of fourteen things, "sniffing around" among them.
Bad news is written by Python, every time: a flustered puppy, the news, a tip, and a promise to help, in the question's language. "Ruh-roh! My ears just flopped over. I sniffed the whole map and found no such place. Try a shorter name, like Chiang Mai. Don't worry, we'll fix it together!" The model is never trusted with it.
Two last clean-ups. The model likes emojis, a 🐱 once, for a puppy, and the browser reads them aloud as "cat face", so they are taken out of what it writes: the face shows the mood instead. And its Thai sometimes gets stuck on one letter, so a run of more than five is cut to three.

WHY PYTHON PICKS THE MOODThe model could be asked for a mood too, but it would sometimes pick an odd one, and it adds seconds to every answer. Python already knows what happened: a map was drawn, a price went down, a search found nothing. The rules are a few lines, and they are never wrong. Letting the model choose, from a fixed list and checked, is a good challenge.จะถามอารมณ์จากโมเดลก็ได้ แต่บางทีมันจะเลือกแปลก ๆ และทำให้ทุกคำตอบช้าลงหลายวินาที Python รู้อยู่แล้วว่าเกิดอะไรขึ้น: วาดแผนที่แล้ว ราคาลง การค้นหาไม่เจออะไร กฎมีไม่กี่บรรทัดและไม่มีวันผิด การให้โมเดลเลือกจากรายการที่กำหนดแล้วตรวจอีกที เป็นโจทย์ที่ดี也可以让模型选心情,但它有时会选得很奇怪,而且每个回答都要多等几秒。Python 本来就知道发生了什么:画了地图、价格跌了、搜索什么都没找到。规则只有几行,而且不会错。让模型从固定的列表里选、再核对一下,是一个好挑战。
THAI IS STILL WEAKBiscuit answers Thai questions in Thai now, but this small model's Thai is hard to follow, and it sometimes echoes a garbled piece of the reminder. The moods, and every bad-news message, are written by Python, so those read well in all three languages.ตอนนี้บิสกิตตอบคำถามภาษาไทยเป็นภาษาไทยแล้ว แต่ภาษาไทยของโมเดลเล็กนี้ยังอ่านยาก และบางทีก็พูดคำเตือนซ้ำแบบเพี้ยน ๆ อารมณ์และข้อความข่าวร้ายทุกข้อ Python เป็นคนเขียน จึงอ่านได้ดีทั้งสามภาษาBiscuit 现在用泰语回答泰语问题了,但这个小模型的泰语还是很难懂,有时还会把提醒的话走样地重复一遍。心情和每一条坏消息都是 Python 写的,所以三种语言都读得通。

The chatbot reads each answer aloud, and a 🔊 button turns that off.
The browser does the speaking, not the Pi, so the Pi does no extra work. Voices are ranked, because the first voice on the list is often the worst one. Chrome's own Google voices come first, then the system's newer voices, and the old Microsoft David and Zira last.
เบราว์เซอร์เป็นคนพูด ไม่ใช่พาย พายจึงไม่ต้องทำงานเพิ่ม เสียงถูกจัดอันดับ เพราะเสียงแรกในรายการมักแย่ที่สุด เสียง Google ของ Chrome มาก่อน ตามด้วยเสียงใหม่ของระบบ และ Microsoft David กับ Zira รุ่นเก่ามาท้ายสุด

聊天机器人会把每个回答念出来,一个 🔊 按钮可以关掉。
说话的是浏览器,不是树莓派,所以树莓派不用多干活。声音要排序,因为列表上第一个往往最差:Chrome 自己的 Google 声音排最前,然后是系统较新的声音,老的 Microsoft David 和 Zira 排最后。

The first version handed everything to an English voice, so Thai and Chinese in an answer came out as mumbling, or not at all. Two more changes fixed it. The answer is cut into pieces by alphabet, and each piece gets a voice for its own language. The second fixed a bug the first one had: a number next to a word in a language with no voice was skipped along with it.

Asked "How do you say thank you in Thai?"; what the chat showed:
Bot: In Thai, you say "ขอบคุณ" which means thank you. It's pronounced as "tub khwan."
(this browser has no Thai voice, so that part was not read)
THAI NEEDS A THAI VOICE ON THE COMPUTERChrome brings a Google voice for Chinese (普通话), but none for Thai. So Thai is read only if the computer itself has a Thai voice. On Windows: Settings → Time & language → Speech → Add voices → Thai. On a Mac: System Settings → Accessibility → Spoken Content → System voice → Manage voices, and add a Thai voice. Without one, the chat says so, as above, instead of mumbling. And read what it says, too: the model spelled ขอบคุณ as "tub khwan". It is khop khun.Chrome มีเสียง Google สำหรับภาษาจีน (普通话) แต่ไม่มีสำหรับภาษาไทย ภาษาไทยจึงจะถูกอ่านก็ต่อเมื่อคอมพิวเตอร์มีเสียงภาษาไทยเอง บน Windows: Settings → Time & language → Speech → Add voices → Thai บน Mac: System Settings → Accessibility → Spoken Content → System voice → Manage voices แล้วเพิ่มเสียงภาษาไทย ถ้าไม่มี แชตจะบอกไว้แบบข้างบน แทนที่จะอ่านอู้อี้ และอ่านสิ่งที่มันเขียนด้วย โมเดลสะกด ขอบคุณ ว่า "tub khwan" ที่ถูกคือ khop khunChrome 自带中文(普通话)的 Google 声音,但没有泰语的。所以只有电脑本身装了泰语声音,泰语才会被念出来。Windows:设置 → 时间和语言 → 语音 → 添加语音 → 泰语。Mac:系统设置 → 辅助功能 → 朗读内容 → 系统声音 → 管理声音,添加一个泰语声音。没有的话,聊天里会像上面那样说明,而不是含糊地念。也要看看它写了什么:模型把 ขอบคุณ 拼成 "tub khwan",正确的是 khop khun。
CHROME FIRST, WINDOWS AS THE FALLBACKThe page does not ask which browser it is in. It asks which voices exist. In Chrome, the Google voices exist and win. In another browser, or a Chrome with no Google voice, they are simply not on the list, so the Windows voices are used, newer ones first. The browser used for this test was that second case: it had only Windows' three old voices, so the ranking chose Zira, the one woman's voice among them. On a Mac, Safari uses the Mac's own voices the same way.หน้าเว็บไม่ได้ถามว่าอยู่ในเบราว์เซอร์อะไร แต่ถามว่ามีเสียงอะไรบ้าง ใน Chrome มีเสียง Google และเสียงนั้นชนะ ในเบราว์เซอร์อื่น หรือ Chrome ที่ไม่มีเสียง Google เสียงเหล่านั้นก็ไม่อยู่ในรายการ จึงใช้เสียงของ Windows แทน โดยเลือกเสียงรุ่นใหม่ก่อน เบราว์เซอร์ที่ใช้ทดสอบคือกรณีที่สอง มันมีแค่เสียงเก่าสามเสียงของ Windows การจัดอันดับจึงเลือก Zira ซึ่งเป็นเสียงผู้หญิงเสียงเดียวในนั้น บน Mac นั้น Safari ใช้เสียงของ Mac เองแบบเดียวกัน网页不问自己在哪个浏览器里,只问有哪些声音。在 Chrome 里有 Google 声音,它们胜出。换一个浏览器,或者 Chrome 里没有 Google 声音,它们就不在列表上,于是用 Windows 的声音,较新的优先。这次测试用的浏览器正是第二种情况:只有 Windows 的三个老声音,所以排序选了 Zira,其中唯一的女声。在 Mac 上,Safari 也同样用 Mac 自己的声音。
THREE LANGUAGES, TWO MODELS, ONE REMINDERThe alphabet of the question decides the model and the reminder. English and Chinese go to biscuit; Thai goes to biscuit-th, made from the older Qwen 2, because Qwen 2.5's Thai came out broken or in Chinese. A one-line reminder in the question's own language, "(ตอบเป็นภาษาไทยเท่านั้น)", answer in Thai only, is added after the question: it took the hard Thai question from Chinese half the time to Thai 35 times in 35. Python still checks the answer's alphabet against the question's, and asks once more if they differ.ตัวอักษรของคำถามเป็นตัวตัดสินโมเดลและคำเตือน ภาษาอังกฤษและจีนไปที่ biscuit ภาษาไทยไปที่ biscuit-th ซึ่งสร้างจาก Qwen 2 รุ่นเก่ากว่า เพราะภาษาไทยของ Qwen 2.5 ออกมาพังหรือเป็นภาษาจีน คำเตือนบรรทัดเดียวในภาษาของคำถาม "(ตอบเป็นภาษาไทยเท่านั้น)" ถูกเติมหลังคำถาม: มันทำให้คำถามภาษาไทยข้อยาก จากที่ตอบเป็นจีนครึ่งหนึ่ง กลายเป็นตอบไทย 35 ครั้งจาก 35 Python ยังตรวจตัวอักษรของคำตอบเทียบกับคำถาม และถามซ้ำอีกครั้งถ้าไม่ตรงกัน问题用的文字决定模型和提醒。英文和中文交给 biscuit;泰文交给由更老的 Qwen 2 做成的 biscuit-th,因为 Qwen 2.5 写的泰文要么坏掉,要么变成中文。在问题后面加一行问题所用语言的提醒,“(ตอบเป็นภาษาไทยเท่านั้น)”,只用泰语回答:那个难的泰语问题从一半时候答成中文,变成 35 次里 35 次答泰语。Python 仍然把回答的文字和问题的文字对一遍,不一致就再问一次。

Biscuit's facts are in biscuit.md: who it is, Eva and Charlie, Peppa Pig, Jay Chou and his music, coin prices. In English, Thai and Chinese, 30 short pieces under 30 headings. LlamaIndex, from the Local AI stack page, reads the file when the chatbot starts, cuts it at the headings, and turns each piece into an embedding on the Pi's processor: a list of numbers that stands for its meaning. A question becomes one too. The nearest pieces, in the question's own language, are handed to Biscuit with the question. Only pieces near enough: the line is 0.40, where 1 is the same meaning.
Measured. Five embedding models on the same 50 questions: the MiniLM already on the Pi separated best. The line was chosen on those 50 and then tried on 44 questions it had never seen. There, questions about Biscuit found their piece 20 times in 22, and questions about the person found one wrongly 2 times in 22: "What is my dog's name?" is near "You are a puppy".
In the chatbot. A fact from three turns back: 4 of 8, up from 3. About itself: 6 of 12. A bitcoin price invented in chat: 0 of 2, down from 2 of 2. Questions about Peppa Pig and Jay Chou: English 8 of 8, Chinese 1 of 2, Thai 0 of 2. It still embroiders: Suzy Sheep became Peppa's "sister-in-law".

27Can ReAct choose the tool? Five models, measured · ReAct เลือกเครื่องมือได้ไหม? ห้าโมเดล วัดผล · ReAct 能选工具吗?五个模型,实测
🇬🇧 English
The Local AI stack page runs an agent: LlamaIndex's ReActAgent, tools from FunctionTool.from_defaults, and Ollama with hermes3:8b. ReAct is plain text. The model writes a Thought, then an Action and its input, reads the Observation the tool sends back, and goes round again until it writes an Answer. It needs no tool calling from the server, so it could be tried on the HAT. Only the choice was tested: stand-in tools with the chatbot's names, the 112 questions of section 33, and 6 conversations of 14 turns.
What ReAct does that Laya could not: read the conversation. After a Bangkok search, "When was the last time it flooded there?" was searched as "last time Bangkok flooded"; "And ethereum?" asked for ETH. Its weak spot is small talk: Hermes made a web page for "Good evening!". The HAT's own model mostly did not use the tools at all, and took 15 seconds a question.
So the agent needs a model the HAT cannot run. Real Ollama can run one, on the Pi's processor: section 14. For comparison, smolagents with Ollama's own tool calling chose right 106 times with Qwen 2.5 3B and 60 with Hermes 8B, whose tool calls came out garbled that way.
สิ่งที่ ReAct ทำได้แต่ Laya ทำไม่ได้: อ่านบทสนทนา หลังค้นหากรุงเทพ "When was the last time it flooded there?" ถูกค้นเป็น "last time Bangkok flooded" "And ethereum?" ถามราคา ETH จุดอ่อนคือการคุยเล่น: Hermes สร้างหน้าเว็บให้ "Good evening!" โมเดลของ HAT เองส่วนใหญ่ไม่ใช้เครื่องมือเลย และใช้เวลา 15 วินาทีต่อคำถาม
Local AI stack 那一页跑的是一个智能体:LlamaIndex 的 ReActAgent,用 FunctionTool.from_defaults 做的工具,加上带 hermes3:8b 的 Ollama。ReAct 是纯文本。模型先写 Thought,再写 Action 和它的输入,读工具送回的 Observation,一轮一轮直到写出 Answer。它不需要服务器支持工具调用,所以能在 HAT 上试。只测选择:用聊天机器人工具名字的替身工具,第 33 节的 112 个问题,和 6 段共 14 轮的对话。
ReAct 做到了 Laya 做不到的:读对话。搜过曼谷之后,"When was the last time it flooded there?"被搜成了"last time Bangkok flooded";"And ethereum?"去问了 ETH。它的弱点是闲聊:Hermes 给"Good evening!"做了个网页。HAT 自己的模型大多根本不用工具,一个问题要 15 秒。

✅ RAN ON THE DGX SPARK · react_probe.py · the agent from agent.py, stand-in tools, 112 questions
"""react_probe.py — can ReAct choose the chatbot's tool?
ReAct is a way of asking: the model writes a Thought, then an Action (a tool
and what to hand it), reads the Observation that comes back, and carries on
until it can write an Answer. It is all plain text, so it needs no tool
calling from the model server. This is the agent in agent.py, from the page
"Local AI stack on Windows": LlamaIndex's ReActAgent, with Ollama behind it.
Only the choice is tested. The tools here are stand-ins with the chatbot's
own names: they look nothing up, they write down that they were called. The
questions are the 76 + 36 of eval_pickers.py, where Laya scored 100 of 112.

🇬🇧 English
✨ Auto is the ReAct agent, as on the Local AI stack page: ReActAgent(tools=..., llm=Ollama(...)). The tools are the chatbot's own functions, and about_biscuit for biscuit.md. It reads the chat's list as chat_history, and the page shows its steps: the tool called, what it found. It runs as an async workflow, on a loop of its own in a thread of its own: a new loop for every question left its connection closed. smolagents is gone from the file.
What it did on the Pi:coin_price for bitcoin, draw_map for Wat Umong, web_search for tomorrow's weather, make_page for a tip calculator, about_biscuit for Eva and Charlie, and the cat's name from the chat, in 20 to 60 seconds a question. Two misses, and they are still there: "And ethereum?" got a guessed price, twice, and its instructions were changed to say it knows no prices at all; on 30 September it guessed again, 1,654,200 baht for Ethereum, invented. "Tell me more about the place" drew the map again, that day too. The run of 30 September is below: after four conversations the Pi went down in the fifth, the heat guard by elimination, section 10.
The heat. The Pi has no fan. Two questions take its processor from 55 to 77 °C, and 82 was seen. The Pi slows itself at 80, and the heat guard shuts it down if it stays there. So at 80 and over, Auto rests: Python answers "Ruh-roh! My processor is hot", no model runs, and the buttons still work. With the official Active Cooler, which fits under the AI HAT+ 2, a Pi 5 stays near 60 under this load.
# ... web_factory.py: ✨ Auto, the ReAct agent# ✨ Auto's model runs on the Pi's processor, in real Ollama, on a port of# its own: Hailo's server has no tool calling, and its model could not# follow ReAct's format (right 33 times in 112).

Two pieces are here: how a browser gets a conversation of its own, and how the page moves between http, https and a shared address.
The name is made in the browser, at random, and 🧹 makes a new one: the Pi then has nothing under it, and the chat starts clean. The addresses: 8080 is plain http; 🗺️ Map moves to the https page, because a browser only tells a secure page where you are; and when the Pi is shared through Tailscale, section 32, that address is used instead, and the Pi's own https is not started.

Everything a student needs to keep the Pi going, change the code without breaking the Pi, and open the chatbot to people beyond the Wi-Fi. Then the numbers that were measured while it was built, and three things to try.
30Log in, start, stop, restart, and shut down · เข้าระบบ เริ่ม หยุด รีสตาร์ต และปิดเครื่อง · 登录、启动、停止、重启和关机
🇬🇧 English
Log in. From any computer on the same Wi-Fi: ssh student@pihat.local, with the student's password from section 7. If the name is not found, section 4 says why, and the Pi's address works instead.
What runs. Five things, and all of them start by themselves when the Pi boots: the chatbot, Biscuit's model server on the HAT, real Ollama for the agent, the relay for a Mac, and the heat guard. The table below names each one, and its port. Tailscale is installed too, logged out until section 32.
Stop, start, restart.sudo systemctl restart web-factory restarts the chatbot, and asks for no password (section 7). Every other stop, start or restart asks for the student's password. Restart the chatbot after changing web_factory.py or biscuit.md; restart hailo-ollama after running make_biscuit.py. A restart of a model server takes a minute: the chatbot's first question after it waits while the models load.
Shut down the right way. Type sudo shutdown -h now, wait until the green light stops blinking, about ten seconds, then pull the plug. Pulling the plug first can damage the card. To start again, plug it in: everything starts by itself within about a minute. sudo reboot does both.

IF THE CHATBOT SAYS IT IS HOT, WAIT"Ruh-roh! My processor is hot" means the Pi is at 80 °C or more. Give it a minute or two. The heat guard shuts the Pi down if it stays over 80: then the green light goes out, and you plug it in again after a rest."อุ๊ย! ตัวประมวลผลของฉันร้อน" แปลว่าพายอยู่ที่ 80 องศาขึ้นไป ให้เวลามันสักหนึ่งหรือสองนาที ตัวเฝ้าความร้อนจะปิดเครื่องถ้ามันอยู่เกิน 80 นาน: ไฟเขียวจะดับ แล้วค่อยเสียบปลั๊กใหม่หลังพักสักครู่"哎呀!我的处理器好热"意思是树莓派到了 80 度或更高。给它一两分钟。一直超过 80 度的话,热保护会关机:绿灯熄灭,让它歇一会儿再插上电源。
This is the whole loop a student will use, run once as the student. There are two ways to change the code. Edit it on the Pi in vim. Or copy it to your laptop, edit it there in any editor, and copy it back with scp. Here the greeting was changed on the laptop and copied back. Then a copy of that working file was kept, and one bracket was broken on purpose in vim. The page stops working, and the log says exactly which line. Copying the good file back fixes it.

READ THE LAST LINE FIRSTWhen the page stops working, systemctl is-active says activating: the service keeps trying again every 10 seconds. The log has the answer. It names the file, the line, and puts a ^ under the problem. Fix that line, restart, and look again.เมื่อหน้าเว็บหยุดทำงาน systemctl is-active จะบอกว่า activating คือบริการพยายามใหม่ทุก 10 วินาที คำตอบอยู่ในบันทึก มันบอกชื่อไฟล์ บรรทัด และใส่ ^ ไว้ใต้จุดที่ผิด แก้บรรทัดนั้น รีสตาร์ต แล้วดูอีกครั้ง网页不工作时,systemctl is-active 会说 activating:服务每 10 秒再试一次。答案在日志里:它写出文件、行号,并在出错的地方下面放一个 ^。改那一行,重启,再看。
CONNECTING A STUDENT'S MAC — NOT TRIED HERE YETOn café or school Wi-Fi, a cable is the sure way. Plug a USB-C Ethernet adapter into the Mac, and a network cable into the Pi. On the Mac, open System Settings → General → Sharing → Internet Sharing. Share from Wi-Fi, to the adapter, and switch it on. The Mac finds pihat.local by itself. The Pi's power still comes from its own 27 W supply. A laptop's USB port cannot run it with the HAT working.บน Wi-Fi ร้านกาแฟหรือโรงเรียน สายแลนคือวิธีที่ชัวร์ เสียบอะแดปเตอร์ USB-C เป็น Ethernet เข้ากับ Mac และเสียบสายแลนเข้ากับพาย บน Mac เปิด System Settings → General → Sharing → Internet Sharing แชร์จาก Wi-Fi ไปที่อะแดปเตอร์ แล้วเปิดใช้งาน Mac หา pihat.local เจอเอง ไฟของพายยังต้องมาจากอะแดปเตอร์ 27 วัตต์ของมันเอง พอร์ต USB ของแล็ปท็อปจ่ายไฟให้มันไม่ไหวเมื่อ HAT ทำงาน在咖啡馆或学校的 Wi-Fi 上,网线最稳。把 USB-C 转以太网适配器插到 Mac 上,网线插到树莓派。在 Mac 上打开 系统设置 → 通用 → 共享 → 互联网共享,从 Wi-Fi 共享到适配器,然后打开。Mac 自己就能找到 pihat.local。树莓派的电仍然来自它自己的 27 瓦电源,HAT 工作时笔记本的 USB 口供不动它。

32Share it: private or public, with Tailscale · แชร์มัน: ส่วนตัวหรือสาธารณะ ด้วย Tailscale · 分享它:私人或公开,用 Tailscale
THE STATE OF THIS PI: PUBLIC, SINCE THE EVENING OF 30 SEPTEMBERThe Pi is logged in to Tailscale as pihat.something.ts.net, and both switches are public: the chatbot answers the whole internet at https://pihat.something.ts.net, and real Ollama at https://pihat.something.ts.net:8443, with a real certificate, nothing to install. Type the https://: the address bar's plain http is refused, because nothing listens on port 80. The switches live in a service drop-in, /etc/systemd/system/web-factory.service.d/share.conf, so neither the code nor the unit file changed; off there and a restart closes both. The steps below are what was done, in order; the run at the end is this Pi today.พายเข้าสู่ระบบ Tailscale ในชื่อ pihat.something.ts.net และสวิตช์ทั้งสองเป็น public: แชตบอตตอบทั้งอินเทอร์เน็ตที่ https://pihat.something.ts.net และ Ollama ตัวจริงที่ https://pihat.something.ts.net:8443 ด้วยใบรับรองจริง ไม่ต้องติดตั้งอะไร พิมพ์ https:// ด้วย: http ธรรมดาจากช่องที่อยู่จะถูกปฏิเสธ เพราะไม่มีอะไรฟังที่พอร์ต 80 สวิตช์อยู่ใน drop-in ของบริการ /etc/systemd/system/web-factory.service.d/share.conf โค้ดและไฟล์ unit จึงไม่เปลี่ยน ใส่ off ตรงนั้นแล้ว restart ก็ปิดทั้งสอง ขั้นตอนข้างล่างคือสิ่งที่ทำจริงตามลำดับ และการรันท้ายสุดคือพายเครื่องนี้วันนี้树莓派已以 pihat.something.ts.net 登录 Tailscale,两个开关都是 public:聊天机器人在 https://pihat.something.ts.net 面向整个互联网回答,真正的 Ollama 在 https://pihat.something.ts.net:8443,带真正的证书,什么都不用装。要把 https:// 打出来:地址栏默认的 http 会被拒绝,因为 80 端口上什么都没有。开关放在服务的 drop-in 里,/etc/systemd/system/web-factory.service.d/share.conf,所以代码和 unit 文件都没改;在那里写 off 再重启,两个都会关掉。下面的步骤就是实际做过的事,按顺序;最后的运行记录是今天这块树莓派的。
SHARE_OLLAMA: THE SECOND SWITCHFunnel can open three ports: 443, 8443 and 10000. The page takes 443. A second setting, SHARE_OLLAMA, with the same three values, puts real Ollama on 8443: start_sharing() in section 29 runs tailscale funnel --bg --https=8443 11435 after the page's own line. From a Mac: OLLAMA_HOST=https://pihat.something.ts.net:8443 ollama run qwen2.5:3b. Both settings can be set in the file, or given to the service in the drop-in, which is what this Pi does.Funnel เปิดได้สามพอร์ต: 443, 8443 และ 10000 หน้าเว็บใช้ 443 ค่าตั้งตัวที่สอง SHARE_OLLAMA ที่มีสามค่าเหมือนกัน เอา Ollama ตัวจริงไปไว้ที่ 8443: start_sharing() ในส่วนที่ 29 รัน tailscale funnel --bg --https=8443 11435 ต่อจากบรรทัดของหน้าเว็บเอง จาก Mac: OLLAMA_HOST=https://pihat.something.ts.net:8443 ollama run qwen2.5:3b ค่าทั้งสองตั้งในไฟล์ก็ได้ หรือส่งให้บริการผ่าน drop-in อย่างที่พายเครื่องนี้ทำFunnel 能开三个端口:443、8443 和 10000。页面占了 443。第二个设置 SHARE_OLLAMA,同样三个值,把真正的 Ollama 放到 8443 上:第 29 节的 start_sharing() 在页面那一行之后运行 tailscale funnel --bg --https=8443 11435。在 Mac 上:OLLAMA_HOST=https://pihat.something.ts.net:8443 ollama run qwen2.5:3b。两个设置可以写在文件里,也可以像这块树莓派一样通过 drop-in 交给服务。
A browser only shares where you are, or a microphone, with a secure page. A secure page needs a certificate that browsers already trust. A real website has one, and so can your Pi. Tailscale gives it a real address and a real certificate, and the people who visit install nothing. You choose who can open it.
Tailscale is already installed on this Pi (below). On another Pi: curl -fsSL https://tailscale.com/install.sh | sh
Once, as the admin, let the chatbot use Tailscale: sudo tailscale set --operator=student
Log the Pi in: sudo tailscale up. It prints a link. Open it and log in with your own Tailscale account. It is free.
In the Tailscale admin console, open DNS. Turn on MagicDNS and HTTPS Certificates.
Now it is one line near the top of web_factory.py: SHARE = os.environ.get("SHARE", "off"). Change "off" to "private" for only your own devices (each needs the Tailscale app, logged in to the same account), or to "public" for anyone who has the link (they install nothing). Then sudo systemctl restart web-factory.
The address it prints looks like https://pihat.something.ts.net. See it with journalctl -u web-factory -n 5. Open it: a padlock, and no warning. On http://pihat.local:8080, 🗺️ Map now moves there too.
To stop sharing, change it back to "off" and restart. "off" tells Tailscale to stop, so off really means off.
Now 📍 Here works for every visitor. For a microphone too, add the code folded below to web_factory.py: inside CHAT_PAGE, the first piece inside the <form>, after the 🔊 button, and the second inside the <script>, just before function write. The doubled braces {{ }} are on purpose: CHAT_PAGE is filled in with .format(), which turns {{ into {. Then sudo systemctl restart web-factory.
All of this was run on this Pi with a Tailscale account: private, public, and back to off. The tests are below, and the Pi was left on "off". While SHARE is on, Tailscale answers https, so the Pi's own https://pihat.local is not started. With it off, that one runs, and every browser warns first, because nobody it trusts vouched for its certificate.
What is it doing?tailscale status says whether the Pi is logged in, and lists your devices. tailscale serve status says what is shared: (tailnet only) is private, Funnel on is public, No serve config is nothing. journalctl -u web-factory -n 5 shows the address the chatbot printed.
"cannot reach the Pi at …" means nothing answered at the address the page came from, so the question never got to the Pi. (Older copies of the chatbot said "Failed to fetch".) On a ts.net page, Tailscale was logged out, or SHARE went back to "off", or the Pi is off. Open http://pihat.local:8080 on the same network, or log in again.
"the Pi answered, but not with an answer" means the Pi is up but something broke: journalctl -u web-factory -n 20 shows what.
"tailscale serve did not work" in the log: Access denied means point 2 was missed. A link to open means HTTPS Certificates (point 4) is off, or, for "public", Funnel is not yet allowed for your account: open the link, allow it, restart.
Why the Pi's own https stops: https uses port 443. While sharing, Tailscale holds 443, so the chatbot starts Tailscale first and does not start its own. Only one program can listen on a port.
Giving the Pi to someone else:sudo tailscale logout first, so it leaves your account. They log it in with sudo tailscale up, and their address is different: pihat. and then their own tailnet's name.
มันกำลังทำอะไรอยู่?tailscale status บอกว่าพายเข้าสู่ระบบอยู่หรือไม่ และแสดงอุปกรณ์ของคุณ tailscale serve status บอกว่าแชร์อะไรอยู่: (tailnet only) คือส่วนตัว Funnel on คือสาธารณะ No serve config คือไม่ได้แชร์ journalctl -u web-factory -n 5 แสดงที่อยู่ที่แชตบอตพิมพ์ออกมา
"cannot reach the Pi at …" แปลว่าไม่มีอะไรตอบที่ที่อยู่ที่หน้านี้มาจาก คำถามจึงไปไม่ถึงพายเลย (แชตบอตรุ่นเก่าจะเขียนว่า "Failed to fetch") ถ้าอยู่บนหน้า ts.net แปลว่า Tailscale ออกจากระบบแล้ว หรือ SHARE กลับเป็น "off" หรือพายปิดอยู่ ให้เปิด http://pihat.local:8080 ในเครือข่ายเดียวกัน หรือเข้าสู่ระบบใหม่
它在做什么?tailscale status 说明树莓派有没有登录,并列出你的设备。tailscale serve status 说明分享了什么:(tailnet only) 是私人,Funnel on 是公开,No serve config 是没分享。journalctl -u web-factory -n 5 显示聊天机器人打印的地址。
"cannot reach the Pi at …" 的意思是这个页面来自的地址没有任何回应,问题根本没到树莓派。(旧版聊天机器人写的是 "Failed to fetch"。)在 ts.net 页面上,说明 Tailscale 退出登录了,或者 SHARE 改回了 "off",或者树莓派关着。在同一个网络里打开 http://pihat.local:8080,或者重新登录。
日志里有 "tailscale serve did not work":Access denied 说明漏了第 2 点。如果给了一个链接,说明 HTTPS Certificates(第 4 点)没开;如果是 "public",也可能是你的账号还没允许 Funnel:打开链接,允许,再 restart。
PUBLIC MEANS ANYONEWith funnel, anyone who has the link can use your chatbot. They use your Pi's AI HAT and its processor, they look things up on Bitkub, DuckDuckGo and OpenStreetMap under your Pi's name, and they can open the maps it has made. Share the link only with people you choose, and think about a password before you share it widely.เมื่อใช้ funnel ทุกคนที่มีลิงก์ใช้แชตบอตของคุณได้ เขาใช้ AI HAT ของพายคุณ ค้นข้อมูลจาก Bitkub DuckDuckGo และ OpenStreetMap ในนามพายของคุณ และเปิดดูแผนที่ที่มันเคยทำได้ แชร์ลิงก์ให้เฉพาะคนที่คุณเลือก และคิดเรื่องรหัสผ่านก่อนจะแชร์ออกไปกว้าง ๆ用 funnel 时,任何有链接的人都能用你的聊天机器人:用你树莓派的 AI HAT,以你树莓派的名义去 Bitkub、DuckDuckGo和 OpenStreetMap 查东西,还能打开它做过的地图。只把链接给你选的人,大范围分享之前,考虑加一个密码。
And Chrome sends what you say to Google to turn it into text. The microphone is the one part of this chatbot that does not stay on your Pi.

33What was measured · สิ่งที่วัดได้ · 测过什么
🇬🇧 English
The chatbot was built in 39 measured steps between 28 and 30 September 2026, and most of what was tried on the way is gone from the code: a router of Python keyword rules, an embeddings picker, a Laya decision model, a page-side history, follow-up rewriting, and a smolagents agent with @tools, which the HAT's server cannot serve. The numbers that decided the design that is here are in this table, with the section that shows each measurement's script and log. The 1.5B model on the HAT is the limit that shows in most of them: it finds the right fact and still writes it wrong about half the time.
Tool choice: which of five tools a message needs, 112 messages in three languagesการเลือกเครื่องมือ: ข้อความหนึ่งต้องการเครื่องมือไหนในห้าตัว 112 ข้อความ สามภาษา选工具:一条消息需要五个工具里的哪个,112 条消息,三种语言
Memory: how to hand the chat back to the HAT's model, 24 tries eachความจำ: จะส่งแชตกลับให้โมเดลของ HAT อย่างไร ลอง 24 ครั้งต่อวิธี记忆:怎样把聊天交回给 HAT 的模型,每种 24 次
pasted into one message 11; real messages 15; real messages that keep what was looked up 19. Temperature made no difference: 12, 13, 10, 10 of 25.แปะรวมเป็นข้อความเดียว 11; ข้อความจริง 15; ข้อความจริงที่เก็บสิ่งที่ค้นได้ 19 temperature ไม่ทำให้ต่าง: 12, 13, 10, 10 จาก 25贴成一条消息 11;真正的消息 15;保留查到内容的真正消息 19。温度没有区别:25 次里 12、13、10、10。
Persona: a fact recalled from two or three turns back, 16 triesบุคลิก: จำข้อเท็จจริงจากสองสามเทิร์นก่อนได้ 16 ครั้ง人设:回忆两三轮前的事实,16 次
with the long persona 2; without the sentence about Eva and Charlie 8; with a one-line persona 9. So the identity is three sentences, and the rest is in biscuit.md.บุคลิกยาว 2; ไม่มีประโยคเรื่องอีวากับชาร์ลี 8; บุคลิกบรรทัดเดียว 9 ตัวตนจึงเหลือสามประโยค ที่เหลืออยู่ใน biscuit.md长人设 2;去掉 Eva 和 Charlie 那句 8;一行人设 9。所以身份只有三句话,其余放在 biscuit.md。

Add a tool that tells the time in any city: a plain function with type hints and a docstring with an Args: section, because FunctionTool.from_defaults reads them to describe the tool to the agent. Put it in the list in make_agent(), section 28, and give it a button too, the way lookup() in section 18 runs the tool a button names. Then ask ✨ Auto "What time is it in Tokyo?" and read the grey lines.
เพิ่มเครื่องมือที่บอกเวลาในเมืองไหนก็ได้: ฟังก์ชันธรรมดาที่มี type hint และ docstring พร้อมส่วน Args: เพราะ FunctionTool.from_defaults อ่านสิ่งเหล่านี้เพื่ออธิบายเครื่องมือให้เอเจนต์ ใส่มันในลิสต์ใน make_agent()ส่วนที่ 28 และให้มันมีปุ่มด้วย แบบที่ lookup() ในส่วนที่ 18 รันเครื่องมือที่ปุ่มบอก แล้วถาม ✨ Auto ว่า "What time is it in Tokyo?" และอ่านบรรทัดสีเทา
加一个能报任何城市时间的工具:一个普通函数,带类型标注和带 Args: 部分的文档字符串,因为 FunctionTool.from_defaults 靠它们向智能体描述这个工具。把它放进 make_agent() 的列表里,第 28 节,也给它一个按钮,就像第 18 节的 lookup() 运行按钮指定的工具那样。然后问 ✨ Auto“What time is it in Tokyo?”,读一读灰色的那几行。
2Break the agent on purposeตั้งใจทำให้เอเจนต์พลาด故意让智能体出错
Find a question where ✨ Auto picks the wrong tool, or none. Section 28 has two that still fail: "And ethereum?" after a bitcoin price gets an invented price, and "Tell me more about the place" after a map draws the map again. Write it down. Then change one thing, a sentence in AGENT_PROMPT or a tool's docstring, and run react_talks.py from section 27 against the Pi's own Ollama, http://localhost:11435 qwen2.5:3b: are the 9 turns of 14 it got right still right? A fix that breaks two others is not a fix.
หาคำถามที่ ✨ Auto เลือกเครื่องมือผิด หรือไม่เลือกเลย ส่วนที่ 28 มีสองข้อที่ยังพลาดอยู่: "And ethereum?" หลังราคาบิตคอยน์ได้ราคาที่แต่งขึ้น และ "Tell me more about the place" หลังแผนที่วาดแผนที่เดิมอีกครั้ง จดไว้ แล้วเปลี่ยนอย่างเดียว ประโยคใน AGENT_PROMPT หรือ docstring ของเครื่องมือ แล้วรัน react_talks.py จากส่วนที่ 27 กับ Ollama ของพายเอง http://localhost:11435 qwen2.5:3b: 9 เทิร์นจาก 14 ที่มันเคยตอบถูกยังถูกไหม การแก้ที่ทำให้อีกสองข้อพังไม่ใช่การแก้
找一个让 ✨ Auto 选错工具、或者不选工具的问题。第 28 节里有两个至今仍会错的:问完比特币价格后的“And ethereum?”得到一个编出来的价格,画完地图后的“Tell me more about the place”又把地图画了一遍。记下来。然后只改一处,AGENT_PROMPT 里的一句话或某个工具的文档字符串,再对着树莓派自己的 Ollama,http://localhost:11435 qwen2.5:3b,跑一遍第 27 节的 react_talks.py:它原来答对的 14 轮里的 9 轮还对吗?弄坏另外两个的修法不算修好。
3Fit a fan, and measure itใส่พัดลม แล้ววัดผล装上风扇,再量一次
The official Active Cooler fits under the AI HAT+ 2. Fit it, then run the heat log from section 10 again during two ✨ Auto questions, and read journalctl -u heat-guard the next day. With the processor kept near 60 °C, how many ✨ Auto questions in a row can the Pi take? That number is the real limit of this chatbot, and it is not in this page yet.
Active Cooler ของทางการใส่ใต้ AI HAT+ 2 ได้ ใส่มัน แล้วรัน log ความร้อนจากส่วนที่ 10 อีกครั้งระหว่างคำถาม ✨ Auto สองข้อ และอ่าน journalctl -u heat-guard ในวันถัดไป เมื่อตัวประมวลผลอยู่ราว 60 °C พายรับคำถาม ✨ Auto ติดกันได้กี่ข้อ ตัวเลขนั้นคือขีดจำกัดจริงของแชตบอตนี้ และยังไม่อยู่ในหน้านี้
官方的 Active Cooler 能装在 AI HAT+ 2 下面。装上它,然后在两个 ✨ Auto 问题期间再跑一次第 10 节的温度日志,第二天读一读 journalctl -u heat-guard。处理器保持在 60 °C 左右时,树莓派能连续接多少个 ✨ Auto 问题?那个数字才是这个聊天机器人的真正上限,这一页里还没有它。
