Summary

作者分享了用 pi agent 通过 models.json 配置四个免费/低成本模型渠道(OpenRouter、百度灵积、阿里云 MaaS、opencode-go)的零成本 AI 编程方案,并给出了避免被静默回退到付费模型的配置踩坑经验,全文以推文串形式展开。

Holy cow! I connected Muse to 4 model channels using pi agent, seamless switching, and didn't spend a single penny!!! Channel list 👇 ① OpenRouter: Free models, automatically scans the list every morning at 8 AM ② Ant Baidu Ling: Official API, Ling-3.1-flash free for two weeks ③ Ant Digital Tech: MaaS channel ④ opencode-go: Subscribe and use directly Defining channels only requires changing one file: ~/.pi/agent/models.json, write provider id + baseUrl + api + key (reference via environment variables, don't hardcode) Hard-earned lesson: defaultModel must write the bare model ID, defaultProvider on a separate line! Writing it as "provider/id" will be silently ignored by pi, falling back to paid models and then 402, I've been burned by this The same pi setup can also schedule image generation: ModelScope Qwen-Image-2.1 async output, 98 keyframes stitched into 148-second 1080p MV. Comment below with 1 if you want the full tutorial 1/ Zero-cost way to set up 4-channel AI coding agent: OpenRouter free models updated daily, all personally tested and working, note: Recharge $5, daily calls increase to 1000 times 2/ Step 1: npm one command to install pi agent 3/ Step 2: models.json defines channels. OpenRouter uses free, Baidu Ling/Digital Tech uses official API, opencode uses subscription, all keys referenced via environment variables 4/ Step 3: Scheduled task scans OpenRouter free list every morning at 8 AM, auto-notify for additions/removals, only enable models verified for both "chat + tool calling" 5/ Step 4: /model or Ctrl+P for seamless switching, --model for single calls.

Holy cow! I connected Muse to 4 model channels using pi agent, seamless switching, and didn’t spend a single penny!!!

Channel list 👇 ① OpenRouter: Free models, automatically scans the list every morning at 8 AM ② Ant Baidu Ling: Official API, Ling-3.1-flash free for two weeks ③ Ant Digital Tech: MaaS channel ④ opencode-go: Subscribe and use directly

Defining channels only requires changing one file: ~/.pi/agent/models.json, write provider id + baseUrl + api + key (reference via environment variables, don’t hardcode)

Hard-earned lesson: defaultModel must write the bare model ID, defaultProvider on a separate line! Writing it as “provider/id” will be silently ignored by pi, falling back to paid models and then 402, I’ve been burned by this

The same pi setup can also schedule image generation: ModelScope Qwen-Image-2.1 async output, 98 keyframes stitched into 148-second 1080p MV. Comment below with 1 if you want the full tutorial

@geekbb: Nice, nice. Using this project to combine free models from major tech companies and pool their quotas together. Don't underestimate the free quotas from these 16 LLM providers (totaling about 1.7 billion tokens per month). If used well, it can save a lot.
