Providers

The server has two provider IDs:

codex
claude

Both providers implement the same ChatProvider interface: stream, complete, and optional aiModel access for tool-using agent turns.

Codex

The codex provider uses the OpenAI AI SDK.

Setting	Value
Required key	`OPENAI_API_KEY`
Default model	`gpt-5.4`
Models	`gpt-5.4`, `gpt-5.4-mini`, `gpt-5.4-nano`

Claude

The claude provider uses the Anthropic AI SDK.

Setting	Value
Required key	`ANTHROPIC_API_KEY`
Default model	`claude-sonnet-4-6`
Models	`claude-sonnet-4-6`, `claude-opus-4-7`, `claude-haiku-4-5`

Provider Info

GET /providers returns the models and whether each provider is configured:

{
  "providers": [
    {
      "id": "codex",
      "label": "Codex",
      "defaultModel": "gpt-5.4",
      "models": ["gpt-5.4", "gpt-5.4-mini", "gpt-5.4-nano"],
      "configured": true
    }
  ]
}

Selection

HTTP requests choose a provider in the request body.

{
  "provider": "codex",
  "model": "gpt-5.4-mini",
  "messages": [{ "role": "user", "content": "Explain this file." }]
}

WebSocket sessions can choose provider and model during session.create. If omitted, the server picks the first available provider.
