Where Mistral Medium 3.5 sits on price

At the reference month of 10M input and 3M output tokens, Mistral Medium 3.5 costs $37.5, which makes it the 19th cheapest of the 30 models tracked here. That is 22× the price of Qwen-Flash, the cheapest model at this mix ($1.70). Among the 11 mid-tier models it ranks 8th, behind MiniMax M3 at $6.60.

Cache economics

Cached input on Mistral Medium 3.5 bills at $0.15 per 1M — 10% of its own input rate, against a 10% median across the models here that publish a cached-read price. 2 models discount cached reads more steeply than this. On the reference month, serving 80% of that input from cache takes the input side of the bill from $15 to $4.20, leaving output untouched at $22.5 — which is why a high reuse rate changes the ranking above rather than just shaving the total.

Cache reads only. Writes are billed separately by some providers and are excluded here — see the rate note above for Mistral's terms. Try it at your own hit rate on the AI cost calculator.
