- Name any Claude model (
claude-sonnet-4-6,claude-opus-4-8, …) and Orbitrage forwards to Anthropic and translates the request behind the scenes. - Or pass
model="auto"and let the router choose an open-weight model. - Tools, streaming, and vision work exactly as in Tool calling and Streaming.
Claude models are BYOK-only. Save and enable an Anthropic key on the
Models page — the call then runs on your
Anthropic account at your rate and Orbitrage charges $0 for the tokens. With
no enabled key,
claude-* returns 403 byok_key_required rather than falling
back to pooled inference. You still call in OpenAI format either way. See
BYOK.
