Where Mistral Large 3 2512 sits on price
At $1.50 per million output tokens, Mistral Large 3 2512 is a mid tier model — 1.4× cheaper than the median output price of $2.08, which puts it cheaper than 60% and pricier than 40% of the models we track. It sits 17th 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.
