Local LLM for VS code copilot

In Config VS Code (Insiders) we see how we can add a custom LLM via the "OpenAI compatible API".

Add in a custom model to copilot in vs code insiders is easy. Let it do agent stuff is really hard.

Here an example: Qwen3 Coder

VS Code JSON:

  "github.copilot.chat.customOAIModels": {
    "Qwen/Qwen3-Coder-30B-A3B-Instruct-FP8": {
      "name": "Qwen/Qwen3-Coder-30B-A3B-Instruct-FP8",
      "url": "http://gate0.neuro.uni-bremen.de:8000/v1",
      "toolCalling": true,
      "vision": false,
      "thinking": true,
      "maxInputTokens": 256000,
      "maxOutputTokens": 8192,      
      "requiresAPIKey": false
    }
