Mercury 2.5 vs Mistral Small 3.2 24B: common questions

Is Mercury 2.5 better than Mistral Small 3.2 24B?

Mercury 2.5 ranks higher on the ModelCap Index as of 10 September 2026: #117 against #120. That is a capability ranking built from public benchmark evidence with published uncertainty; whether it is "better" for you also depends on price, context and where you can run it. Their published uncertainty intervals overlap, so the rank difference alone does not establish a reliable capability advantage for your workload.

Is Mercury 2.5 cheaper than Mistral Small 3.2 24B?

Mercury 2.5 is cheaper on output tokens: $0.15/1M against $0.20/1M. Input tokens are $0.04/1M for Mercury 2.5 and $0.075/1M for Mistral Small 3.2 24B. Prices are the lowest listed API offer ModelCap observed, in USD per million tokens. For 1,000 requests with 2,000 input and 500 output tokens each (2M input + 0.5M output), the listed-rate estimate is $0.15 for Mercury 2.5 versus $0.25 for Mistral Small 3.2 24B. Mercury 2.5 costs 38.0% less in this scenario. This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the selected endpoint before budgeting.

Which has the bigger context window, Mercury 2.5 or Mistral Small 3.2 24B?

Mercury 2.5 has the larger context window: 260K tokens against 131K.

Which is better for coding, Mercury 2.5 or Mistral Small 3.2 24B?

The two models do not share a coding benchmark board on ModelCap yet, so no head-to-head coding score is published; the ModelCap Index position is the closest overall signal.

Are Mercury 2.5 and Mistral Small 3.2 24B open-weight models?
