Pricing per 1M tokens
| Item | Price / 1M tokens |
|---|---|
| Input | $0.10 |
| Output | $0.10 |
| Cache read | $0.01 |
| Batch inputBatch requests | $0.05 |
| Batch outputBatch requests | $0.05 |
Note: Batch prices come from the pricing page's Batch mode, which applies a factor of 0.5 to standard prices. Priority Tier adds 75% and regional inference adds 10%. The docs give the context only as '256k'. No primary page states a max output. Base and Reasoning weights are also published, all Apache 2.0. The gateway id mistral/ministral-3b is unversioned and lists a 131072 context, which does not match the docs. Its price ($0.1/$0.1 with a $0.01 cache read) does match Ministral 3 3B, and the older ministral-3b-2410 was retired 2025-12-30. Re-check this mapping if the gateway changes. The model card is dated December 2, 2025; release date uses the changelog date (December 1).
