Gemini 3.7 Flash vs Mistral Nemo
A straight cost comparison of Gemini 3.7 Flash (Google Gemini) and Mistral Nemo (Mistral AI), per 1,000,000 tokens, verified November 2026.
Rate-by-rate comparison
| Metric | Gemini 3.7 Flash | Mistral Nemo | Winner |
|---|---|---|---|
| Input / 1M | $0.75 | $0.15 | Mistral Nemo |
| Cached input / 1M | $0.075 | $0.015 | Mistral Nemo |
| Cache write / 1M |  |  | Tie |
| Output / 1M | $3.75 | $0.15 | Mistral Nemo |
| Context window | 1,000,000 | 128,000 | Gemini 3.7 Flash |
| Batch API | Yes | Yes | Tie |
| Long-context tier | > 200,000 | None |  |
For per-token metrics, the lower number wins. For context window and batch support, the higher or broader option wins. A dash means the provider does not publish that rate: a missing cache-write fee means writes are not billed per token, while a missing cached-input rate means cache hits bill at the full input rate.
Blended cost: 1M input + 250K output
| Model | Blended cost | Difference |
|---|---|---|
| Gemini 3.7 Flash | $1.69 | +$1.50 |
| Mistral Nemo | $0.188 | Cheaper |
Ten workloads, two bills
The same two models, priced across ten workloads that differ only in their input:output ratio. Nothing else changes  no retries, no system prompt, no middleware.

Gemini 3.7 Flash wins 0 of 10, Mistral Nemo wins 10 of 10. The winner is set by the token mix, not by the headline rate.
Where the two bills cross over
Mistral Nemo is cheaper on both sides of the mix: $0.15 vs $0.75 per million input tokens, and $0.15 vs $3.75 per million output. No input:output ratio reverses that, so on price alone the other model never becomes the better choice  it has to win on context, latency or output quality.
Cost at four scales
The same support-chat workload (4K input, 600 output per request) at four monthly volumes.
| Requests / month | Gemini 3.7 Flash | Mistral Nemo | Difference |
|---|---|---|---|
| 100 | $0.525 | $0.069 | Mistral Nemo cheaper by $0.456 |
| 1,000 | $5.25 | $0.69 | Mistral Nemo cheaper by $4.56 |
| 10,000 | $52.50 | $6.90 | Mistral Nemo cheaper by $45.60 |
| 100,000 | $525 | $69 | Mistral Nemo cheaper by $456 |
What caching does to each bill
Caching only helps the part of the prompt that repeats. This is the support-chat workload (1,000 requests, 4,000 input tokens each) with an increasing share of that prompt served from a warm cache, written once on the first request.
| Cached share of the prompt | Gemini 3.7 Flash | Mistral Nemo | Winner |
|---|---|---|---|
| 0% | $5.25 | $0.69 | Mistral Nemo |
| 50% | $3.90 | $0.42 | Mistral Nemo |
| 80% | $3.09 | $0.258 | Mistral Nemo |
| 95% | $2.69 | $0.178 | Mistral Nemo |
Both models publish a cached-read rate, so the discount is comparable: Gemini 3.7 Flash reads cache at $0.075 per million, Mistral Nemo at $0.015.
Which one should you pick?
Gemini 3.7 Flash wins on none of the ten workloads above, while Mistral Nemo wins on classification, data extraction, support chat, code review, summarisation, agent loop, translation, long-document qa, cached rag, nightly batch.
Beyond price, the two differ on input rate ($0.75 vs $0.15); output rate ($3.75 vs $0.15); cached-input rate ($0.075 vs $0.015); context window (1,000,000 vs 128,000); long-context tier (yes, above 200,000 vs none).
Batch mode is available on Gemini 3.7 Flash and Mistral Nemo, which halves the nightly job. Both publish cached-input discounts, so a stable system prompt is worth caching on either.
