BES normalizes admitted public benchmark evidence for measured Index rows. Its legacy score and observables prior do not define the public language rank.
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.

Gemma 4 31B holds ModelCap Index position #37 of 352 ranked language models as of 6 November 2026, with an Index score of 71.9 (interval 66.4–77.4); evidence: measured. The Index combines public benchmark boards with published uncertainty; the methodology page explains the weighting.
Gemma 4 31B is listed at $0.20 per 1M input tokens and $0.40 per 1M output tokens as of 6 November 2026; the lowest output price among 16 providers is $0.10 on Modal. Prices come from the OpenRouter catalogue and re-observe on every refresh; at least one provider lists a free tier. For 1,000 requests using 2,000 input and 500 output tokens each, the listed rates imply $0.60 total (2M input + 0.5M output). This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the chosen endpoint's rate and limits before budgeting.
Gemma 4 31B has a published context window of 262K tokens (262,144). The snapshot lists a 16,384 token catalogue-declared route output cap. OpenRouter catalogue or provider-endpoint declaration.
