Which should you choose?
Which is better: GPT-5.2 Pro, Claude Opus 4.6 or Qwen3.7 Max?
It is close. Our weighted score puts them within 3 points (Claude Opus 4.6 61/100, Qwen3.7 Max 58/100, GPT-5.2 Pro 56/100), so choose by what matters most for your work: GPT-5.2 Pro for raw capability and Qwen3.7 Max on price. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.
Which is cheaper, GPT-5.2 Pro, Claude Opus 4.6 or Qwen3.7 Max?
Qwen3.7 Max is cheaper at $2.50 input / $7.50 output per million tokens (official Alibaba API price). Claude Opus 4.6 costs $5.00 input / $25.00 output per million tokens (official Anthropic API price); GPT-5.2 Pro costs $21.00 input / $168.00 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $3.75 per million tokens for Qwen3.7 Max versus $10.00 for Claude Opus 4.6 (2.7× as much) and $57.75 for GPT-5.2 Pro (15× as much).
Which scores higher on benchmarks?
GPT-5.2 Pro scores higher on the Capabilities Index (ECI): GPT-5.2 Pro 155.4 (#25 of 148), Claude Opus 4.6 155.3 (#27 of 148) and Qwen3.7 Max 153.7 (#37 of 148). The confidence ranges of the top two overlap (153.0–158.2 vs 153.4–157.3), so treat the gap as small. On individual benchmarks: FrontierMath Tiers 1–3 — GPT-5.2 Pro 74.0%, Claude Opus 4.6 66.0%, Qwen3.7 Max 64.6%.
Which is better for coding?
There are no published SWE-bench Verified results for GPT-5.2 Pro yet, so there is no like-for-like coding score. On overall capability, GPT-5.2 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?
Claude Opus 4.6 and Qwen3.7 Max have the largest context windows (1,000,000 and 1,000,000 tokens), against 400,000 for GPT-5.2 Pro. Maximum output per response: GPT-5.2 Pro up to 128,000, Claude Opus 4.6 up to 128,000, Qwen3.7 Max up to 65,536 tokens.
Which can read images, PDFs, audio or video?
GPT-5.2 Pro accepts text and images; Claude Opus 4.6 accepts text, images and PDFs; Qwen3.7 Max accepts text. Claude Opus 4.6 handles the widest range of inputs.
Are any of these open source?
No. GPT-5.2 Pro, Claude Opus 4.6 and Qwen3.7 Max are proprietary and only available through APIs and apps.
Which is newer?
Qwen3.7 Max is the newest, released May 21, 2026. Claude Opus 4.6 came out Feb 5, 2026; GPT-5.2 Pro came out Dec 11, 2025. Knowledge cutoff: GPT-5.2 Pro Aug 31, 2025, Claude Opus 4.6 May 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.
