Where Mixtral 8x22B Instruct sits on price
At $6.00 per million output tokens, Mixtral 8x22B Instruct is a premium tier model — 2.9× the median output price of $2.08, which puts it cheaper than 29% and pricier than 71% of the models we track. It sits 23th 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 Mixtral 8x22B Instruct
These three workloads are the ones teams actually run on a premium-priced model — a $6.00/1M model is not bought for the same job as one ten times the price.

| Coding agent — 300 sessions/day (60K in / 12K out) Multi-step loops re-read the same files; caching matters more than raw price. | $0.192 | $1728 |
