01 — Verdict

Too close to call

It is close. Our weighted score puts them within a point (Qwen2.5 72B Instruct 28/100, Sonar Reasoning Pro 27/100, Mistral Large 2.1 26/100), so choose by what matters most for your work: Qwen2.5 72B Instruct on price. 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.

04 — Questions

Which should you choose?

Which is better: Mistral Large 2.1, Sonar Reasoning Pro or Qwen2.5 72B Instruct?

It is close. Our weighted score puts them within a point (Qwen2.5 72B Instruct 28/100, Sonar Reasoning Pro 27/100, Mistral Large 2.1 26/100), so choose by what matters most for your work: Qwen2.5 72B Instruct on price. 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, Sonar Reasoning Pro or Qwen2.5 72B Instruct?

Qwen2.5 72B Instruct is cheaper at $1.40 input / $5.60 output per million tokens (official Alibaba API price). Mistral Large 2.1 costs $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 $2.45 per million tokens for Qwen2.5 72B Instruct versus $3.00 for Mistral Large 2.1 (1.2× as much) and $3.50 for Sonar Reasoning Pro (1.4× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers all three models yet. Mistral Large 2.1 has an ECI of 128.5, Sonar Reasoning Pro has not been scored yet and Qwen2.5 72B Instruct has an ECI of 129.0.

Which is better for coding?

There are no published SWE-bench Verified results for Mistral Large 2.1, Sonar Reasoning Pro and Qwen2.5 72B Instruct 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 and Qwen2.5 72B Instruct have the largest context windows (131,072 and 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, Qwen2.5 72B Instruct up to 8,192 tokens.

Which can read images, PDFs, audio or video?

Mistral Large 2.1 accepts text; Sonar Reasoning Pro accepts text and images; Qwen2.5 72B Instruct accepts text. Sonar Reasoning Pro handles the widest range of inputs.

Are any of these open source?

Mistral Large 2.1 and Qwen2.5 72B Instruct 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. Qwen2.5 72B Instruct came out Sep 19, 2024; Sonar Reasoning Pro came out Jan 1, 2024. Knowledge cutoff: Mistral Large 2.1 Nov 2024, Sonar Reasoning Pro Sep 1, 2025, Qwen2.5 72B Instruct Apr 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 Oct 4, 2026.
