Too close to call
It is close. Our weighted score puts them within 2 points (Qwen Max 22/100, Sonar Pro 20/100, Qwen-MT Plus 12/100), so choose by what matters most for your work: Qwen Max on price and Sonar Pro 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: Sonar Pro, Qwen-MT Plus or Qwen Max?
It is close. Our weighted score puts them within 2 points (Qwen Max 22/100, Sonar Pro 20/100, Qwen-MT Plus 12/100), so choose by what matters most for your work: Qwen Max on price and Sonar Pro 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, Sonar Pro, Qwen-MT Plus or Qwen Max?
Qwen Max is cheaper at $1.60 input / $6.40 output per million tokens (official Alibaba API price). Qwen-MT Plus costs $2.46 input / $7.37 output per million tokens (official Alibaba API price); Sonar Pro costs $3.00 input / $15.00 output per million tokens (official Perplexity API price). At a typical mix of three input tokens to one output token, that is $2.80 per million tokens for Qwen Max versus $3.69 for Qwen-MT Plus (1.3× as much) and $6.00 for Sonar Pro (2.1× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Sonar Pro has not been scored yet, Qwen-MT Plus has not been scored yet and Qwen Max has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Sonar Pro, Qwen-MT Plus and Qwen Max yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Sonar Pro and Qwen-MT Plus does not support tool calling, which most coding agents need.
Which has the bigger context window?
Sonar Pro has the largest context window at 200,000 tokens, against 32,768 for Qwen Max and 16,384 for Qwen-MT Plus. Maximum output per response: Sonar Pro up to 8,192, Qwen-MT Plus up to 8,192, Qwen Max up to 8,192 tokens.
Which can read images, PDFs, audio or video?
Sonar Pro accepts text and images; Qwen-MT Plus accepts text; Qwen Max accepts text. Sonar Pro handles the widest range of inputs.
Are any of these open source?
No. Sonar Pro, Qwen-MT Plus and Qwen Max are proprietary and only available through APIs and apps.
Which is newer?
Qwen-MT Plus is the newest, released Jan 2025. Qwen Max came out Apr 3, 2024; Sonar Pro came out Jan 1, 2024. Knowledge cutoff: Sonar Pro Sep 1, 2025, Qwen-MT Plus Apr 2024, Qwen Max 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.
