Too close to call
It is close. Our weighted score puts them within 1 points (Sonar Reasoning Pro 27/100, Mistral Large 2.1 26/100), so choose by what matters most for your work: Mistral Large 2.1 on price and Mistral Large 2.1 for long inputs. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

Which should you choose?
Which is better: Mistral Large 2.1 or Sonar Reasoning Pro?
It is close. Our weighted score puts them within 1 points (Sonar Reasoning Pro 27/100, Mistral Large 2.1 26/100), so choose by what matters most for your work: Mistral Large 2.1 on price and Mistral Large 2.1 for long inputs. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.
Which is cheaper, Mistral Large 2.1 or Sonar Reasoning Pro?
Mistral Large 2.1 is cheaper at $2.00 input / $6.00 output per million tokens (official Mistral API price). Sonar Reasoning Pro costs $2.00 input / $8.00 output per million tokens (official Perplexity API price). At a typical mix of three input tokens to one output token, that is $3.00 per million tokens for Mistral Large 2.1 versus $3.50 for Sonar Reasoning Pro (1.2× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers both models yet. Mistral Large 2.1 has an ECI of 128.5 and Sonar Reasoning Pro has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Mistral Large 2.1 and Sonar Reasoning Pro yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Sonar Reasoning Pro does not support tool calling, which most coding agents need.
Which has the bigger context window?
Mistral Large 2.1 has the largest context window at 131,072 tokens, against 128,000 for Sonar Reasoning Pro. Maximum output per response: Mistral Large 2.1 up to 16,384, Sonar Reasoning Pro up to 4,096 tokens.
Which can read images, PDFs, audio or video?
Mistral Large 2.1 accepts text; Sonar Reasoning Pro accepts text and images. Sonar Reasoning Pro handles the widest range of inputs.
Are any of these open source?
Mistral Large 2.1 publishes its weights and can be self-hosted; Sonar Reasoning Pro is proprietary.
Which is newer?
Mistral Large 2.1 is the newest, released Nov 18, 2024. Sonar Reasoning Pro came out Jan 1, 2024. Knowledge cutoff: Mistral Large 2.1 Nov 2024, Sonar Reasoning Pro Sep 1, 2025.
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 Oct 4, 2026.
