Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
GPT-5.2 Instant is clearly ahead on the aggregate, 85 to 43. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-5.2 Instant's sharpest advantage is in coding, where it averages 75.5 against 21.5. The single biggest benchmark swing on the page is SWE-bench Verified, 75 to 17.
GPT-5.2 Instant is also the more expensive model on tokens at $1.50 input / $6.00 output per 1M tokens, versus $0.55 input / $2.19 output per 1M tokens for DeepSeek-R1. That is roughly 2.7x on output cost alone.
Pick GPT-5.2 Instant if you want the stronger benchmark profile. DeepSeek-R1 only becomes the better choice if you want the cheaper token bill.
