Why this result
DeepSeek V4 Pro has the cleaner BenchAlign overall profile here, landing at 60.66 versus 58.43. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
DeepSeek V4 Pro's sharpest advantage is in agentic, where it averages 59.1 against 55.7. The single biggest benchmark swing on the page is GPQA, 72.9% to 92.4%. GPT-5.2 does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
GPT-5.2 is also the more expensive model on tokens at $1.75 input / $14.00 output per 1M tokens, versus $0.43 input / $0.87 output per 1M tokens for DeepSeek V4 Pro. That is roughly 16.1x on output cost alone. GPT-5.2 is the reasoning model in the pair, while DeepSeek V4 Pro 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. DeepSeek V4 Pro gives you the larger context window at 1M, compared with 400K for GPT-5.2.
