    Mask FAQ

    Who ranks #1 on the Mask leaderboard?

    As of August 20, 2026, Grok-4.1 Thinking by xAI ranks #1 on Mask at 51%. API pricing is $3.00/M input and $15.00/M output.

    Which mask model is the cheapest?

    Grok-4.1 Thinking currently leads Mask and is also the cheapest scored model on this page, at $3.00/M input and $15.00/M output ($18.00 blended).

    Should I always pick the #1 Mask model?

    Not automatically. Grok-4.1 Thinking leads Mask, but a cheaper scored model can be the better production choice if the quality gap is small. Use the table to weigh Mask against input/output price, context window, and related evals.

    How often is the Mask leaderboard updated?

    Scores and API prices on this page are refreshed from published evals and provider rates. The snapshot is labeled August 20, 2026. Treat it as a current index, not a one-off blog post.

    What is Mask?

    Mask is a public LLM eval (the Mask score). This page ranks models that have published a score, next to live API prices.

    Where is the Mask leaderboard?

    This page is the Mask leaderboard. Models are sorted by Mask, with input and output token prices on the same row so you can weigh score against cost. Official boards often omit price; that comparison is the point of this index.

    How is this Mask ranking different from the official board?

    Official eval pages own the methodology. This page keeps the published Mask score next to live API $/M so you can pick a production SKU, not only a trophy number.
