  Context from the model table; max_tokens maximum 524288 from the Messages API reference; image and video input and tool-use blocks from the Anthropic compatibility page. The Responses API reference allows only text as text.format type, and the chat-completions reference says response_format is supported only by MiniMax-Text-01, so structured output is recorded as unsupported.
