A model ID from the current catalog — real provider model names, all MiniMax. The core tiers are minimax-m3 (flagship), minimax-m2.7 (balanced daily driver) and minimax-m2.5 (fast); the -highspeed variants are latency-tuned versions of their standard siblings at roughly 2x the price; minimax-m2.1 and minimax-m2 are older M-series generations; minimax-m2-her is role-play/dialogue chat tuning; minimax-text-01 is the long-context text model. There are no invented aliases; any other ID returns an error. The catalog can change with notice.

The conversation so far — an array of role/content messages, oldest first.

Maximum number of tokens to generate in the completion.

Sampling temperature. Lower is more deterministic, higher is more creative. Alter this or top_p, not both.

Nucleus sampling — only tokens in the top top_p probability mass are considered. Alter this or temperature, not both.

Number of completion choices to generate per request.

Set true for a Server-Sent Events stream of deltas.

Up to 4 sequences where generation stops (string or array).

Penalize tokens by how often they already appeared — positive values reduce verbatim repetition.

Penalize tokens that appeared at all — positive values push toward new topics.

Function tools the model may call. Supported — the gateway passes tool definitions and tool-call turns through to the upstream model.

Controls tool use. auto (the default) and none are honoured by the M-series. required and the named-function object are accepted by the API but ignored by the model, which decides for itself. Tested 2026-07-26. Design for a model that chooses, and always handle a turn with no tool call.
