Mistral Medium 3.5 holds ModelCap Index position #81 of 352 ranked language models as of 6 November 2026, with an Index score of 61.0 (interval 56.1–65.9); evidence: measured. The Index combines public benchmark boards with published uncertainty; the methodology page explains the weighting.
Mistral Medium 3.5 is listed at $1.50 per 1M input tokens and $7.50 per 1M output tokens as of 6 November 2026. Prices come from the OpenRouter catalogue and re-observe on every refresh. For 1,000 requests using 2,000 input and 500 output tokens each, the listed rates imply $6.75 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.
Mistral Medium 3.5 has a published context window of 262K tokens (262,144). The snapshot lists a 209,715 token catalogue-declared route output cap.
