FAQ

What providers are supported?

See the providers for the implementation.

• GOOGLE_API_KEY supports google/* models.
• OPENAI_API_KEY supports openai/* models.
• XAI_API_KEY supports xai/* models.

Set a custom OpenAI endpoint with OPENAI_API_URL to use OpenRouter

How does this work?

Claude Code has added support for customizing the Anthropic endpoint with ANTHROPIC_BASE_URL.

anyclaude spawns a simple HTTP server that translates between Anthropic's format and the AI SDK format, enabling support for any AI SDK provider (e.g., Google, OpenAI, etc.)

Do other models work better in Claude Code?

Not really, but it's fun to experiment with them.

ANTHROPIC_MODEL and ANTHROPIC_SMALL_MODEL are supported with the <provider>/ syntax.
