Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
GPT-5.2 is clearly ahead on the aggregate, 77 to 62. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-5.2 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. GPT-5.2 gives you the larger context window at 400K, compared with 200K for Composer 2.
Pick GPT-5.2 if you want the stronger benchmark profile. Composer 2 only becomes the better choice if agentic is the priority or you want the cheaper token bill.
