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

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: 14.7
OpenRouter weekly popularity: Not listed

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

No matched Arena rating

This model is visible because it is available in the live catalogue, but it has no trustworthy community result yet. ModelCap does not infer a quality score from price, features, or market activity.

LLaDA2.1 mini: common questions

How does LLaDA2.1 mini rank among AI models?

LLaDA2.1 mini is a superseded version and is not on the current board as of 24 October 2026. Its archive position, where one exists, is shown on the page; the newer version carries the current rank.

How much does LLaDA2.1 mini cost per 1M tokens?

No live API price is listed for LLaDA2.1 mini in the current snapshot as of 24 October 2026 because the latest endpoint refresh was unavailable. ModelCap shows a price only when a provider currently lists one.

Is LLaDA2.1 mini open-weight?

Open weights (apache-2.0). Downloadable weights are published under an OSI or free-culture license in the current repository metadata. This describes weight availability, not whether the full training stack qualifies as Open Source AI. The repository is inclusionAI/LLaDA2.1-mini on Hugging Face.

When was LLaDA2.1 mini released?

LLaDA2.1 mini first appeared in the catalogue on 9 Feb 2026. It has since been superseded by LLaDA2.2 mini. Rank and price movements since then are recorded on the site's changes feed.
