Pick GPT-5.2 if you want the stronger benchmark profile. Qwen3 235B 2507 only becomes the better choice if you want the cheaper token bill or you would rather avoid the extra latency and token burn of a reasoning model.

Confidence note. This is a partial-evidence comparison with 1 shared benchmark result across 1 evidence category; 1 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.

Why this result

GPT-5.2 has the cleaner BenchAlign overall profile here, landing at 58.43 versus 56.02. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

GPT-5.2's sharpest advantage is in knowledge, where it averages 92.4 against 78.9. The single biggest benchmark swing on the page is GPQA, 92.4% to 77.5%.

GPT-5.2 is also the more expensive model on tokens at $1.75 input / $14.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Qwen3 235B 2507. That is roughly Infinityx on output cost alone. GPT-5.2 is the reasoning model in the pair, while Qwen3 235B 2507 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. GPT-5.2 gives you the larger context window at 400K, compared with 128K for Qwen3 235B 2507.
