Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
GPT-4.1 is clearly ahead on the aggregate, 67 to 62. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-4.1's sharpest advantage is in agentic, where it averages 64.7 against 61.7. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 61.7% to 61%.
GPT-4.1 is also the more expensive model on tokens at $2.00 input / $8.00 output per 1M tokens, versus $0.50 input / $2.50 output per 1M tokens for Composer 2. That is roughly 3.2x on output cost alone. Composer 2 is the reasoning model in the pair, while GPT-4.1 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-4.1 gives you the larger context window at 1M, compared with 200K for Composer 2.
Pick GPT-4.1 if you want the stronger benchmark profile. Composer 2 only becomes the better choice if you want the cheaper token bill or you want the stronger reasoning-first profile.
