Mistral Small 3 vs GPT-5.6 Sol
Published LiveBench scores across all seven categories, live list pricing, context windows, and the measured cost of a point of capability — for both models, side by side.
Mistral Small 3 is the cheaper of the two; neither can be ranked on quality here.
Mistral Small 3 does not have a published LiveBench run, so this comparison covers price, context and declared capabilities only. A missing score means "not evaluated", not "worse" — the right way to separate these two is an eval on your own workload.

Does Mistral Small 3 or GPT-5.6 Sol have a bigger context window?
GPT-5.6 Sol has the larger context window: 33K for Mistral Small 3 against 1.1M for GPT-5.6 Sol. Note that a window you can fill is not a window you should fill — retrieval quality usually degrades well before the limit, and you pay for every token you put in it.
Do Mistral Small 3 and GPT-5.6 Sol support prompt caching?
GPT-5.6 Sol publishes a cached-input rate of $0.200 per million tokens against a full input rate of $2.00. The catalogue lists no separate cached rate for Mistral Small 3, which means the provider does not price it separately here — not that caching is unavailable.

How these numbers are produced
- Price — provider list price from OpenRouter, refreshed every 15 minutes. “Blended” is a 3:1 input:output mix.
- Scores — LiveBench release 2026-06-25, using their own category map. Each model shows its strongest published run. A blank means “not evaluated”, never “bad”.
- Cost per point — the measured dollars LiveBench spent on the run, divided by the score it earned.
- “Win” — awarded only past a threshold: one full point on a benchmark score, 10% on a price, 25% on a context window. Anything tighter reports as a tie, because effort settings alone move a LiveBench score by more than that.
