Using Github Copilot API key as OpenAI key

[higgsboz-beam]

Just wanted to document this as it took me a bit to figure out. If you have a Github Copilot key, you can use it with taskmaster instead of an OpenAI key. This is how you do it:

• Connect your GH account to a Jetbrains IDE
  • I've noticed if I do this with other IDE's they don't request the correct permissions. So you'll get a forbidden when making the request with taskmaster
• Get the key in ~/.config/github-copilot/apps.json (on MacOS, not sure about Windows)
• Set the following in your .env in your project folder

OPENAI_API_KEY=<your-key>
OPENAI_BASE_URL=https://api.githubcopilot.com

• Your providers in config.json can look like this

  "models": {
    "main": {
      "provider": "openai",
      "modelId": "gpt-4o",
      "maxTokens": 16384,
      "temperature": 0.2
    },
    "research": {
      "provider": "openai",
      "modelId": "gpt-4o",
      "maxTokens": 16384,
      "temperature": 0.2
    },
    "fallback": {
      "provider": "openai",
      "modelId": "gpt-4o",
      "maxTokens": 16384,
      "temperature": 0.2
    }
  },

• I haven't been able to get some other models like claude-3.7-sonnet to work even though they're returned in this api call

curl -s https://api.githubcopilot.com/models \
  -H "Authorization: Bearer <your-token>" \
  -H "Content-Type: application/json" \
  -H "Copilot-Integration-Id: vscode-chat" | jq -r '.data[].id'
