Which should you choose?
Which is better: o1, Qwen3 Max or Claude Opus 4?
It is close. Our weighted score puts them within a point (Qwen3 Max 50/100, o1 49/100, Claude Opus 4 48/100), so choose by what matters most for your work: Claude Opus 4 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, o1, Qwen3 Max or Claude Opus 4?
Qwen3 Max is cheaper at $1.20 input / $6.00 output per million tokens (official Alibaba API price). o1 costs $15.00 input / $60.00 output per million tokens (official OpenAI API price); Claude Opus 4 costs $15.00 input / $75.00 output per million tokens (median across 5 API providers). At a typical mix of three input tokens to one output token, that is $2.40 per million tokens for Qwen3 Max versus $26.25 for o1 (11× as much) and $30.00 for Claude Opus 4 (13× as much).
Which scores higher on benchmarks?
Claude Opus 4 scores higher on the Capabilities Index (ECI): Claude Opus 4 142.7 (#87 of 148), Qwen3 Max 142.4 (#91 of 148) and o1 141.9 (#92 of 148). The confidence ranges of the top two overlap (140.2–144.2 vs 140.0–144.6), so treat the gap as small. On individual benchmarks: GPQA Diamond — o1 76.8%, Claude Opus 4 76.3%, Qwen3 Max 72.6%; OTIS Mock AIME 2024–2025 — o1 73.3%, Qwen3 Max 73.3%, Claude Opus 4 64.4%.
Which is better for coding?
There are no published SWE-bench Verified results for o1 and Qwen3 Max yet, so there is no like-for-like coding score. On overall capability, Claude Opus 4 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 o1 and 200,000 for Claude Opus 4. Maximum output per response: o1 up to 100,000, Qwen3 Max up to 65,536, Claude Opus 4 up to 32,000 tokens.
Which can read images, PDFs, audio or video?
o1 accepts text, images and PDFs; Qwen3 Max accepts text; Claude Opus 4 accepts text, images and PDFs. o1 handles the widest range of inputs.
Are any of these open source?
No. o1, Qwen3 Max and Claude Opus 4 are proprietary and only available through APIs and apps.
Which is newer?
Qwen3 Max is the newest, released Sep 23, 2025. Claude Opus 4 came out May 22, 2025; o1 came out Dec 5, 2024. Knowledge cutoff: o1 Sep 2023, Qwen3 Max Apr 2025, Claude Opus 4 Mar 31, 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.
