Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Grok 4.1 is clearly ahead on the aggregate, 84 to 56. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Grok 4.1's sharpest advantage is in coding, where it averages 73.4 against 27.6. The single biggest benchmark swing on the page is SWE-bench Verified, 77 to 24.
Grok 4.1 is also the more expensive model on tokens at $3.00 input / $15.00 output per 1M tokens, versus $0.08 input / $0.30 output per 1M tokens for Seed 1.6 Flash. That is roughly 50.0x on output cost alone. Seed 1.6 Flash is the reasoning model in the pair, while Grok 4.1 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. Grok 4.1 gives you the larger context window at 1M, compared with 256K for Seed 1.6 Flash.
Pick Grok 4.1 if you want the stronger benchmark profile. Seed 1.6 Flash only becomes the better choice if you want the cheaper token bill or you want the stronger reasoning-first profile.
