anthropic_modelenumno"claude-sonnet-5-5"Choose the Claude model to pair with DeepSeek R1 0528 reasoning. The R1 model produces the chain-of-thought; the Claude model synthesizes the final answer. Claude Opus 5.5 also thinks before it answers, and its thinking counts toward max_tokens. An unknown or retired model returns a 400 error that lists the models you can use. · Allowed: claude-sonnet-5-5, claude-haiku-5-5, claude-opus-5-5
