Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
GPT-5.4 Pro is clearly ahead on the aggregate, 91 to 85. 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 87.4 against 75.5. The single biggest benchmark swing on the page is MRCRv2, 97 to 84.
GPT-5.4 Pro is also the more expensive model on tokens at $30.00 input / $180.00 output per 1M tokens, versus $1.50 input / $6.00 output per 1M tokens for GPT-5.2 Instant. That is roughly 30.0x on output cost alone. GPT-5.4 Pro gives you the larger context window at 1.05M, compared with 128K for GPT-5.2 Instant.
Pick GPT-5.4 Pro if you want the stronger benchmark profile. GPT-5.2 Instant only becomes the better choice if you want the cheaper token bill.
