Which should you choose?
Which is better: Claude Opus 4.1, Qwen3 Max or o3-pro?
It is close. Our weighted score puts them within 2 points (o3-pro 51/100, Qwen3 Max 50/100, Claude Opus 4.1 49/100), 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, Claude Opus 4.1, Qwen3 Max or o3-pro?
Qwen3 Max is cheaper at $1.20 input / $6.00 output per million tokens (official Alibaba API price). Claude Opus 4.1 costs $15.00 input / $75.00 output per million tokens (median across 14 API providers); 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 $30.00 for Claude Opus 4.1 (13× as much) and $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), Claude Opus 4.1 144.1 (#81 of 148) and Qwen3 Max 142.4 (#91 of 148). The confidence ranges of the top two overlap (145.8–149.7 vs 141.6–146.0), so treat the gap as small.
Which is better for coding?
There are no published SWE-bench Verified results for Qwen3 Max and o3-pro 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. All three 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 Claude Opus 4.1 and 200,000 for o3-pro. Maximum output per response: Claude Opus 4.1 up to 32,000, Qwen3 Max up to 65,536, o3-pro up to 100,000 tokens.
Which can read images, PDFs, audio or video?
Claude Opus 4.1 accepts text, images and PDFs; Qwen3 Max accepts text; o3-pro accepts text and images. Claude Opus 4.1 handles the widest range of inputs.
Are any of these open source?

Which is newer?
Qwen3 Max is the newest, released Sep 23, 2025. Claude Opus 4.1 came out Aug 5, 2025; o3-pro came out Jun 10, 2025. Knowledge cutoff: Claude Opus 4.1 Mar 31, 2025, Qwen3 Max Apr 2025, o3-pro May 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.
