Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.
GPT-5.4 Pro is clearly ahead on the aggregate, 94 to 43. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-5.4 Pro's sharpest advantage is in coding, where it averages 89 against 24. The single biggest benchmark swing on the page is SWE-bench Verified, 86 to 17.
GPT-5.4 Pro is also the more expensive model on tokens at $30.00 input / $180.00 output per 1M tokens, versus $0.55 input / $2.19 output per 1M tokens for DeepSeek-R1. That is roughly 82.2x on output cost alone. GPT-5.4 Pro gives you the larger context window at 1.05M, compared with 128K for DeepSeek-R1.
Pick GPT-5.4 Pro if you want the stronger benchmark profile. DeepSeek-R1 only becomes the better choice if you want the cheaper token bill.
