AI 导读

Simon Willison 发布 llm-chat-completions-server 0.1a0 插件，可在本地 9001 端口启动一个兼容 OpenAI Chat Completions API 的服务器，暴露 LLM 工具中所有已安装的模型。

推荐理由

Simon 把 LLM 工具变成了兼容 OpenAI 的 API 服务器，开发者可以本地直接用任何模型，省去适配工作，安装即用，实用性强。

A key goal of the new content-addressable logs in LLM 0.32rc1 was being able to support OpenAI Chat Completion style requests where each incoming message extends the previous conversation, like this:

curl http://localhost:8002/v1/chat/completions \
  -H 'Content-Type: application/json' \
  -d '{
    "model": "qwen3.5-4b",
    "messages": [
      {"role": "user", "content": "Capital of France?"},
      {"role": "assistant", "content": "Paris."},
      {"role": "user", "content": "Germany?"}
    ]
  }'

Here the conversation state is tracked by the client, so each of these requests gets longer and longer. The new schema design in LLM is designed to de-duplicate these using hashes of the individual message parts.

To test that out, I built this plugin:

uv tool install llm --pre
llm install llm-chat-completions-server
llm chat-completions-server -p 9001

Running this starts a localhost server on port 9001 that exposes your full collection of LLM models (from any plugins you have installed) using a ChatGPT Completions compatible endpoint.
