Full specs, context window and API limits →How much does Mistral Small 3.1 cost per million tokens?
Mistral Small costs $0.15 per million input tokens and $0.60 per million output tokens ($0.2625/M blended at 3:1). Provides lightweight European sovereign AI with 128K context and rapid instruction following. Verified 2026-09-08.
How much does Mistral Small 3.1 cost per 1,000 requests?
Computed from generated token pricing. Each row assumes the listed input and output tokens per request; output is adjusted by this model's measured 0.85× verbosity factor.
| Request shape | Input tokens | Output tokens | Cost / 1,000 requests |
|---|---|---|---|
| Short | 100 | 50 | $0.0405 |
| Medium | 1,000 | 500 | $0.4050 |
| Long | 4,000 | 2,000 | $1.6200 |
Formula: ((input price × input tokens) + (output price × output tokens × verbosity factor)) ÷ 1,000,000 × 1,000. Assumptions: short 100/50, medium 1,000/500, long 4,000/2,000 input/output tokens per request. Verbosity run: 2026-06-16T20:31:30.728Z.
Three model-specific pricing decisions
Small owns everyday extraction, chat, and vision-shaped decision economics. Image units are not converted from text tokens.
1. Extraction, chat, and vision-shaped bills
| Workload | Fixed shape | 100K bill | Image-unit boundary |
|---|---|---|---|
| Extraction | 2,000 / 400 | $54.00 | Text tokens |
| Chat | 1,000 / 500 | $45.00 | Text tokens |
| Vision-shaped | 2,000 text + image | $54.00 | Image unit unavailable; text row is not an image bill |
2. Small versus Ministral accepted-result crossover
| Fixed input / output | Mistral Small 3.1 | Ministral 8B | Narrow decision boundary |
|---|---|---|---|
| Short task · 1,000 / 300 | $33.00 | $19.50 | 10% accepted-result uplift required |
| 256K-shaped task · 256,000 / 2,000 | $3960.00 | $3870.00 | 15% accepted-result uplift required |
Formula: requests × (input tokens × input $/M + output tokens × output $/M) ÷ 1,000,000. The uplift is a planning threshold, not a measured quality claim.
3. Dated family price / TTFT / throughput ordering
| Model | Verified rates | Speed evidence | Ordering boundary |
|---|---|---|---|
| Mistral Small 3.1 | 2026-08-14 · $0.15 / $0.60 per M | 121 tokens/sec; TTFT 260 ms; 5 measured samples | Price/speed input only; no family verdict |
| Mistral Large 3 | 2026-08-14 · $0.50 / $1.50 per M | 61 tokens/sec; TTFT 400 ms; 5 measured samples | Price/speed input only; no family verdict |
| Mistral Medium 3 | 2026-08-14 · $1.50 / $7.50 per M | 92 tokens/sec; TTFT 320 ms; 5 measured samples | Price/speed input only; no family verdict |
