docs(cookbooks): use OpenAI / non-Anthropic models via a gateway#4
Merged
Conversation
The agent surfaces run Claude Code (`claude`), which speaks the Anthropic Messages API (/v1/messages). OpenAI speaks /v1/chat/completions — a different schema — so LITELLM_BASE_URL can't point straight at api.openai.com. Document the bridge: a LiteLLM proxy that exposes an Anthropic-format endpoint and translates to OpenAI (or Azure/Bedrock/Gemini/vLLM/Ollama). Adds an OpenAI row to the model-endpoint table + a minimal litellm-config.yaml + run + secrets example, and the why. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

What
Documents how to run the agent loop on OpenAI (and Azure/Bedrock/Gemini/vLLM/Ollama).
Key reality: the agent surfaces run Claude Code (
claude), which speaks the Anthropic Messages API (/v1/messages). OpenAI's/v1/chat/completionsis a different schema, soLITELLM_BASE_URLcan't point straight atapi.openai.com. The bridge is a proxy (LiteLLM) that exposes an Anthropic-format endpoint and translates to OpenAI.Adds to
docs/cookbooks/README.md:litellm-config.yamlmappingclaude-3-5-sonnet-20241022→openai/gpt-4o, the run command, and the secrets pointing at the proxy (not OpenAI directly)Generic, no internal infra (leakage gate green).
