Frequently asked questions
How much does Mistral Medium 3.5 cost per 1M tokens?
Mistral Medium 3.5 costs $1.50 per million input tokens and $7.50 per million output tokens at Mistral AI list prices. Output is 5.0x the input rate, so the input:output ratio of your workload drives the real cost more than the headline price.
Does Mistral Medium 3.5 support prompt caching?
Yes. Cached input is billed at $0.150 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 Medium 3.5?
Requests submitted through the asynchronous batch endpoint are billed at 50% off both input and output rates, bringing input to $0.750 and output to $3.75 per million tokens.
What is Mistral Medium 3.5's context window?
256K tokens of context with up to 256K 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.
