What Mistral Small costs at three real workloads
Sticker prices rarely match the invoice. These three workloads use the rates above, with cache writes charged once per job and the batch discount applied only where the provider offers it.
| Workload | Requests | Tokens | Estimated cost |
|---|---|---|---|
| Support chat | 1,000 | 4K in / 600 out | $0.58 |
| RAG with caching | 1,000 | 50K in (45K cached) / 1K out | $1.25 |
| Nightly batch job | 10,000 | 10K in / 2K out | $8 |
Caching the 45K-token prefix saves about 76% on the RAG workload versus sending it uncached every call ($5.30 → $1.25). Batch mode halves the nightly job.
