09 / A FEW MORE DETAILS

Questions worth asking.

Quick answers, drawn from this model’s connected specifications.

How much does MiniMax-M2.1 cost?

Catalog starting rates are $0.3 per million input tokens and $1.2 per million output tokens. Cache-read pricing is $0.03 per million tokens. Compare provider routes and service tiers above for their specific prices.

How much context can it handle?

204,800 tokens in the catalog context window. The catalog lists a maximum of 131,072 completion tokens. Provider limits can differ.

Does it support tools and structured output?

Tool calling: listed as supported. Structured outputs: not listed. See the provider feature matrix for route-specific differences.

How should I interpret these benchmark results?

Read the benchmark name, exact version, metric, source, and model configuration together. Different evaluation settings can change the result. Preference ratings and source-defined composite indices remain separate from task accuracy.

Are these prices and provider measurements live?

This page uses dated source snapshots. Catalog data was observed on 17 Oct 2026. Provider routes were observed on 17 Oct 2026. Missing measurements are not estimated or treated as zero.
