Pick DeepSeek V4 Flash (Max) if you want the stronger benchmark profile. Gemini 2.5 Pro only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
DeepSeek V4 Flash (Max) is clearly ahead on the provisional aggregate, 77 to 65. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
DeepSeek V4 Flash (Max)'s sharpest advantage is in knowledge, where it averages 60 against 40.8. The single biggest benchmark swing on the page is HLE, 34.8% to 18.8%.
Gemini 2.5 Pro is also the more expensive model on tokens at $1.25 input / $10.00 output per 1M tokens, versus $0.14 input / $0.28 output per 1M tokens for DeepSeek V4 Flash (Max). That is roughly 35.7x on output cost alone. DeepSeek V4 Flash (Max) is the reasoning model in the pair, while Gemini 2.5 Pro 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.
DeepSeek V4 Flash (Max) is ahead on BenchLM's provisional leaderboard, 77 to 65. The biggest single separator in this matchup is HLE, where the scores are 34.8% and 18.8%.
