Which should you choose?
Which is better: QVQ Max, Qwen-MT Plus or Sonar Deep Research?
QVQ Max is the better all-round choice, scoring 40/100 against Sonar Deep Research (20) and Qwen-MT Plus (12). It leads on price and inputs & features. 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, QVQ Max, Qwen-MT Plus or Sonar Deep Research?
QVQ Max is cheaper at $1.20 input / $4.80 output per million tokens (official Alibaba API price). Sonar Deep Research costs $2.00 input / $8.00 output per million tokens (official Perplexity API price); Qwen-MT Plus costs $2.46 input / $7.37 output per million tokens (official Alibaba API price). At a typical mix of three input tokens to one output token, that is $2.10 per million tokens for QVQ Max versus $3.50 for Sonar Deep Research (1.7× as much) and $3.69 for Qwen-MT Plus (1.8× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. QVQ Max has not been scored yet, Qwen-MT Plus has not been scored yet and Sonar Deep Research has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for QVQ Max, Qwen-MT Plus and Sonar Deep Research yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Qwen-MT Plus and Sonar Deep Research does not support tool calling, which most coding agents need.
Which has the bigger context window?

Which can read images, PDFs, audio or video?
QVQ Max accepts text and images; Qwen-MT Plus accepts text; Sonar Deep Research accepts text. QVQ Max handles the widest range of inputs.
Are any of these open source?
No. QVQ Max, Qwen-MT Plus and Sonar Deep Research are proprietary and only available through APIs and apps.
Which is newer?
QVQ Max is the newest, released Mar 25, 2025. Sonar Deep Research came out Feb 1, 2025; Qwen-MT Plus came out Jan 2025. Knowledge cutoff: QVQ Max Apr 2024, Qwen-MT Plus Apr 2024, Sonar Deep Research Jan 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.
