Where Codestral 2508 (batch) sits on price
At $0.45 per million output tokens, Codestral 2508 (batch) is a budget tier model — 4.6× cheaper than the median output price of $2.08, which puts it cheaper than 81% and pricier than 19% of the models we track. It sits 10th cheapest of the 25 Mistral models we track. Output is only 3.0× the input price, an unusually flat spread: long prompts hurt about as much as long answers, so prompt size is where the savings are.
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 Codestral 2508 (batch)
These three workloads are the ones teams actually run on a budget-priced model — a $0.45/1M model is not bought for the same job as one ten times the price.
| Workload | Per request | Per month |
|---|---|---|
| High-volume classification — 200K requests/day (400 in / 20 out) Short output, huge volume: the input price dominates the bill. | $0.0001 | $414 |
| Small app — 1K requests/day (500 in / 150 out) The baseline most side projects actually run at. | $0.0001 | $4.27 |
| Document pipeline — 10K docs/day (3K in / 500 out) Batch-friendly: no user waiting, so a ~50% batch discount usually applies. | $0.0007 | $203 |

› What does it cost to fill Codestral 2508 (batch)'s 256K context window?

› Is Codestral 2508 (batch) worth the price?
Codestral 2508 (batch) is in the cheapest end of the market — cheaper than 81% of the models we track. At this price the question is not cost but capability: it is a good fit for classification, extraction, routing and bulk summarisation, and a poor fit for multi-step reasoning where a wrong answer costs more than the tokens saved.
