Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
DeepSeek V3 is clearly ahead on the aggregate, 25 to 18. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
DeepSeek V3's sharpest advantage is in mathematics, where it averages 90.2 against 37. The single biggest benchmark swing on the page is MMLU, 38% to 88.5%. Claude 4.1 Opus Thinking does hit back in reasoning, so the answer changes if that is the part of the workload you care about most.
Claude 4.1 Opus Thinking is the reasoning model in the pair, while DeepSeek V3 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. Claude 4.1 Opus Thinking gives you the larger context window at 200K, compared with 128K for DeepSeek V3.
Pick DeepSeek V3 if you want the stronger benchmark profile. Claude 4.1 Opus Thinking only becomes the better choice if reasoning is the priority or you need the larger 200K context window.
