Which should you choose?
Which is better: Sonar Reasoning Pro, Qwen2.5-VL 72B Instruct or Qwen Max?
It is close. Our weighted score puts them within 3 points (Qwen2.5-VL 72B Instruct 30/100, Sonar Reasoning Pro 27/100, Qwen Max 22/100), so choose by what matters most for your work: Qwen Max on price and Qwen2.5-VL 72B Instruct 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 Reasoning Pro, Qwen2.5-VL 72B Instruct or Qwen Max?
Qwen Max is cheaper at $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); Qwen2.5-VL 72B Instruct costs $2.80 input / $8.40 output per million tokens (official Alibaba 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 $3.50 for Sonar Reasoning Pro (1.3× as much) and $4.20 for Qwen2.5-VL 72B Instruct (1.5× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Sonar Reasoning Pro has not been scored yet, Qwen2.5-VL 72B Instruct 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 Reasoning Pro, Qwen2.5-VL 72B Instruct 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 Reasoning Pro does not support tool calling, which most coding agents need.
Which has the bigger context window?
Qwen2.5-VL 72B Instruct has the largest context window at 131,072 tokens, against 128,000 for Sonar Reasoning Pro and 32,768 for Qwen Max. Maximum output per response: Sonar Reasoning Pro up to 4,096, Qwen2.5-VL 72B Instruct up to 8,192, Qwen Max up to 8,192 tokens.

Which is newer?
Qwen2.5-VL 72B Instruct is the newest, released Sep 2024. Qwen Max came out Apr 3, 2024; Sonar Reasoning Pro came out Jan 1, 2024. Knowledge cutoff: Sonar Reasoning Pro Sep 1, 2025, Qwen2.5-VL 72B Instruct 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.
