Too close to call
It is close. Our weighted score puts them within 1 points (Mistral Small 3.1 24B 40/100, Mistral Small 3 39/100), so choose by what matters most for your work: Mistral Small 3 for raw capability and Mistral Small 3.1 24B for long inputs. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%. Capability uses the average of shared benchmarks (GPQA Diamond and OTIS Mock AIME 2024–2025), because Mistral Small 3 has no Capabilities Index score yet.

Which should you choose?
Which is better: Mistral Small 3 or Mistral Small 3.1 24B?
It is close. Our weighted score puts them within 1 points (Mistral Small 3.1 24B 40/100, Mistral Small 3 39/100), so choose by what matters most for your work: Mistral Small 3 for raw capability and Mistral Small 3.1 24B for long inputs. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%. Capability uses the average of shared benchmarks (GPQA Diamond and OTIS Mock AIME 2024–2025), because Mistral Small 3 has no Capabilities Index score yet.
Which is cheaper, Mistral Small 3 or Mistral Small 3.1 24B?
Mistral Small 3 is cheaper at $0.05 input / $0.08 output per million tokens (median across 6 API providers). Mistral Small 3.1 24B costs $0.351 input / $0.555 output per million tokens (median across 9 API providers). At a typical mix of three input tokens to one output token, that is $0.058 per million tokens for Mistral Small 3 versus $0.402 for Mistral Small 3.1 24B (7× as much).
Which scores higher on benchmarks?
Not every model here has a Capabilities Index score, so we compare the average of shared benchmarks (GPQA Diamond and OTIS Mock AIME 2024–2025): Mistral Small 3 27.0% and Mistral Small 3.1 24B 26.7%. On individual benchmarks: GPQA Diamond — Mistral Small 3.1 24B 47.5%, Mistral Small 3 47.3%; OTIS Mock AIME 2024–2025 — Mistral Small 3 6.7%, Mistral Small 3.1 24B 5.8%.
Which is better for coding?
There are no published SWE-bench Verified results for Mistral Small 3 and Mistral Small 3.1 24B yet, so there is no like-for-like coding score. On overall capability, Mistral Small 3 leads, which tends to carry over to coding, but test on your own codebase. Note that Mistral Small 3 does not support tool calling, which most coding agents need.

Which is newer?
Mistral Small 3.1 24B is the newest, released Mar 17, 2025. Mistral Small 3 came out Jan 30, 2025. Knowledge cutoff: Mistral Small 3 Oct 31, 2023, Mistral Small 3.1 24B Jun 2024.
How do you decide the winner?
Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Nov 2, 2026.
