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 48. 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 multimodal & grounded, where it averages 73.1 against 48.3. The single biggest benchmark swing on the page is MMMU-Pro, 74 to 42. Mistral 8x7B does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
Seed 1.6 Flash is the reasoning model in the pair, while Mistral 8x7B 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 Mistral 8x7B.
Pick Seed 1.6 Flash if you want the stronger benchmark profile. Mistral 8x7B only becomes the better choice if knowledge is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
