Where Codestral 2508 sits on price
At $0.9 per million output tokens, Codestral 2508 is a mid tier model — 2.3× cheaper than the median output price of $2.08, which puts it cheaper than 71% and pricier than 29% of the models we track. It sits 15th 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
These three workloads are the ones teams actually run on a mid-priced model — a $0.9/1M model is not bought for the same job as one ten times the price.

› Is Codestral 2508 worth the price?
Codestral 2508 sits in the middle of the market (15 of 25 by price within Mistral). The honest test is a routing experiment: send the same 200 real requests to this model and to a tier below, and compare failure rate against the price gap — most teams find a majority of traffic never needed the pricier model.
