DeepSeek V3 vs o1

Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.

o1 finishes one point ahead overall, 26 to 25. That is enough to call, but not enough to treat as a blowout. This matchup comes down to a few meaningful edges rather than one model dominating the board.

o1's sharpest advantage is in knowledge, where it averages 75.7 against 69.6. The single biggest benchmark swing on the page is AIME 2024, 39.2% to 74.3%. DeepSeek V3 does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.

o1 is also the more expensive model on tokens at $15.00 input / $60.00 output per 1M tokens, versus $0.27 input / $1.10 output per 1M tokens for DeepSeek V3. That is roughly 54.5x on output cost alone. o1 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. o1 gives you the larger context window at 200K, compared with 128K for DeepSeek V3.

Quick Verdict

Pick o1 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.
