Not independent measurement

Structured rows reported in this exact model repository at the pinned revision below. They are the publisher talking about itself: never measured evidence, never a score input on their own. They remain quarantined until dataset revision, harness, configuration and identity pass ModelCap’s independent admission review.

These adoption and deployment observations remain context only. They do not change this model's ModelCap Index score or rank.

BES evidence selected · measured input only

The bounded 0–100 capability score blends each source’s competitive placement with its published achievement, then combines capability families. Evidence breadth adds a modest uncertainty adjustment; price and popularity are not part of benchmark-led rank.

Market Gravity uses OpenRouter’s full-catalogue popularity order. Sparse Vercel top-ten observations appear only when published and do not affect the score.

Arena preference

Configuration results available

Arena has published current community results for Preview. No default-configuration result is published, so the raw Arena field stays configuration-specific. The strongest supported result can still inform ModelCap Score with reduced confidence.

MiniMax M2.1: common questions

How does MiniMax M2.1 rank among AI models?

MiniMax M2.1 is a superseded version and is not on the current board as of 6 November 2026. Its archive position, where one exists, is shown on the page; the newer version carries the current rank.

How much does MiniMax M2.1 cost per 1M tokens?

No live API price is listed for MiniMax M2.1 in the current snapshot as of 6 November 2026 because no serving endpoint is published. ModelCap shows a price only when a provider currently lists one.

What is the context window of MiniMax M2.1?

MiniMax M2.1 has a published context window of 205K tokens (204,800). The snapshot lists a 131,072 token catalogue-declared route output cap. OpenRouter catalogue or provider-endpoint declaration. Limits can vary by provider and prompt length; a model-wide maximum has not been independently verified. The providers table lists each endpoint's context limit.

Is MiniMax M2.1 open-weight?

Restricted license (modified-mit). Downloadable weights use a model-specific or use-restricted license. Review the linked license before use, redistribution, or commercial deployment. The repository is MiniMaxAI/MiniMax-M2.1 on Hugging Face.

Which benchmarks has MiniMax M2.1 been evaluated on?

MiniMax M2.1 has published results on 2 public boards tracked by ModelCap as of 6 November 2026: Arena text 1385 (#188 of 419) and Arena coding 1437 (#174 of 414). Each board page ranks every tracked model on that benchmark. The ModelCap Index scores the results its methodology admits, with published uncertainty, and shows reference boards without scoring them.

When was MiniMax M2.1 released?

MiniMax M2.1 first appeared in the catalogue on 23 Dec 2025. It has since been superseded by MiniMax M3. Rank and price movements since then are recorded on the site's changes feed.
