AnthropicRequest

Defined in: adapters/anthropic.ts:122

Anthropic Messages API request structure.

Defines all parameters for making a request to Claude via Anthropic’s Messages API. Key differences from OpenAI: system message is a separate parameter (not in messages), max_tokens is required, and supports top_k sampling parameter.
