Too close to call
It is close. Our weighted score puts them within 2 points (Sonar 30/100, Sonar Reasoning Pro 27/100, Qwen Max 22/100), so choose by what matters most for your work: Sonar 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 should you choose?
Which is better: Qwen Max, Sonar or Sonar Reasoning Pro?
It is close. Our weighted score puts them within 2 points (Sonar 30/100, Sonar Reasoning Pro 27/100, Qwen Max 22/100), so choose by what matters most for your work: Sonar 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, Qwen Max, Sonar or Sonar Reasoning Pro?
Sonar is cheaper at $1.00 input / $1.00 output per million tokens (official Perplexity API price). Qwen Max costs $1.60 input / $6.40 output per million tokens (official Alibaba 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 $1.00 per million tokens for Sonar versus $2.80 for Qwen Max (2.8× as much) and $3.50 for Sonar Reasoning Pro (3.5× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Qwen Max has not been scored yet, Sonar has not been scored yet and Sonar Reasoning Pro has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Qwen Max, Sonar 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 and Sonar Reasoning Pro does not support tool calling, which most coding agents need.
Which has the bigger context window?
Sonar and Sonar Reasoning Pro have the largest context windows (128,000 and 128,000 tokens), against 32,768 for Qwen Max. Maximum output per response: Qwen Max up to 8,192, Sonar up to 4,096, Sonar Reasoning Pro up to 4,096 tokens.
Which can read images, PDFs, audio or video?
Qwen Max accepts text; Sonar accepts text; Sonar Reasoning Pro accepts text and images. Sonar Reasoning Pro handles the widest range of inputs.
Are any of these open source?
No. Qwen Max, Sonar and Sonar Reasoning Pro are proprietary and only available through APIs and apps.
Which is newer?
Qwen Max is the newest, released Apr 3, 2024. Sonar came out Jan 1, 2024; Sonar Reasoning Pro came out Jan 1, 2024. Knowledge cutoff: Qwen Max Apr 2024, Sonar Sep 1, 2025, 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.
