Where Mistral Medium 3 sits on price
At $2.00 per million output tokens, Mistral Medium 3 is a mid tier model — right at the median output price of $2.08, which puts it cheaper than 53% and pricier than 47% of the models we track. It sits 20th cheapest of the 25 Mistral models we track. Output costs 5.0× input, the usual spread — trim both, starting with the answer length.
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.
