Frequently asked questions
How much does Mistral Small 4 cost per 1M tokens?
Mistral Small 4 costs $0.150 per million input tokens and $0.600 per million output tokens at Mistral AI list prices. Output is 4.0x the input rate, so the input:output ratio of your workload drives the real cost more than the headline price.
Does Mistral Small 4 support prompt caching?
Yes. Cached input is billed at $0.015 per million tokens, 10x cheaper than uncached input. There is no cache-write premium, so caching is never a net loss.
What is the batch discount for Mistral Small 4?
Requests submitted through the asynchronous batch endpoint are billed at 50% off both input and output rates, bringing input to $0.075 and output to $0.300 per million tokens.
What is Mistral Small 4's context window?
131K tokens of context with up to 8.2K output tokens per request. A larger context window raises the ceiling on what you can send, not the price per token — but filling it on every request is one of the most common causes of an unexpected bill.
Running Mistral Small 4 in production?
Finitizer TokenOps attributes real token spend to teams, features, and prompts — so you find out which workload moved the bill before the invoice does.
