Which should you choose?
Which is better: o3-pro or Qwen3 Max?
It is close. Our weighted score puts them within 2 points (o3-pro 51/100, Qwen3 Max 50/100), so choose by what matters most for your work: o3-pro for raw capability, Qwen3 Max on price and Qwen3 Max for long inputs. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.
Which is cheaper, o3-pro or Qwen3 Max?
Qwen3 Max is cheaper at $1.20 input / $6.00 output per million tokens (official Alibaba API price). o3-pro costs $20.00 input / $80.00 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $2.40 per million tokens for Qwen3 Max versus $35.00 for o3-pro (15× as much).
Which scores higher on benchmarks?
o3-pro scores higher on the Capabilities Index (ECI): o3-pro 147.4 (#60 of 148) and Qwen3 Max 142.4 (#91 of 148). Their confidence ranges do not overlap (145.8–149.7 vs 140.0–144.6), so the gap is a real one.
Which is better for coding?
There are no published SWE-bench Verified results for o3-pro and Qwen3 Max yet, so there is no like-for-like coding score. On overall capability, o3-pro leads, which tends to carry over to coding, but test on your own codebase. Both support tool calling for agent workflows.
Which has the bigger context window?
Qwen3 Max has the largest context window at 262,144 tokens, against 200,000 for o3-pro. Maximum output per response: o3-pro up to 100,000, Qwen3 Max up to 65,536 tokens.
Which can read images, PDFs, audio or video?
o3-pro accepts text and images; Qwen3 Max accepts text. o3-pro handles the widest range of inputs.
Are any of these open source?
No. o3-pro and Qwen3 Max are proprietary and only available through APIs and apps.
Which is newer?
Qwen3 Max is the newest, released Sep 23, 2025. o3-pro came out Jun 10, 2025. Knowledge cutoff: o3-pro May 2024, Qwen3 Max Apr 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.
