Where Mistral Large 4 sits on price
At $4.18 per million output tokens, Mistral Large 4 is a mid tier model — 1.9× the median output price of $2.16, which puts it cheaper than 38% and pricier than 62% of the models we track. It sits 22th cheapest of the 26 Mistral models we track. Output costs 3.1× input, the usual spread — trim both, starting with the answer length.
Cached input is 90% cheaper. On an input-heavy workload you need roughly a 28% cache-hit rate to take 25% off the input line — reachable for chatbots and agents that resend the same system prompt and history.
What real workloads cost on Mistral Large 4
These three workloads are the ones teams actually run on a mid-priced model — a $4.18/1M model is not bought for the same job as one ten times the price.
| Workload | Per request | Per month |
|---|---|---|
| Support chatbot — 500 conversations/day (5K in / 1.4K out) Conversation history re-sent each turn — the classic prompt-caching win. | $0.0127 | $190 |
| Document pipeline — 10K docs/day (3K in / 500 out) Batch-friendly: no user waiting, so a ~50% batch discount usually applies. | $0.0062 | $1851 |
| Long-context analysis — 200 runs/day (250K in / 4K out) Only possible on large-context models; input cost is nearly the whole bill. | $0.3567 | $2140 |
