Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Seed 1.6 Flash is clearly ahead on the aggregate, 56 to 46. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Seed 1.6 Flash's sharpest advantage is in agentic, where it averages 54.5 against 39.8. The single biggest benchmark swing on the page is MRCRv2, 74 to 54.
Seed 1.6 Flash is the reasoning model in the pair, while Gemini 1.0 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. Seed 1.6 Flash gives you the larger context window at 256K, compared with 32K for Gemini 1.0 Pro.
Pick Seed 1.6 Flash if you want the stronger benchmark profile. Gemini 1.0 Pro only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
