Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
GPT-4o is clearly ahead on the aggregate, 34 to 25. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-4o's sharpest advantage is in reasoning, where it averages 62.9 against 24.9. The single biggest benchmark swing on the page is SimpleQA, 24.9% to 64%. DeepSeek V3 does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.
GPT-4o is also the more expensive model on tokens at $2.50 input / $10.00 output per 1M tokens, versus $0.27 input / $1.10 output per 1M tokens for DeepSeek V3. That is roughly 9.1x on output cost alone.
Pick GPT-4o if you want the stronger benchmark profile. DeepSeek V3 only becomes the better choice if mathematics is the priority or you want the cheaper token bill.
