Grok 4 vs Seed 1.6

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

Grok 4 finishes one point ahead overall, 66 to 65. 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.

Grok 4's sharpest advantage is in mathematics, where it averages 85.1 against 75.9. The single biggest benchmark swing on the page is HMMT Feb 2023, 84 to 68. Seed 1.6 does hit back in instruction following, so the answer changes if that is the part of the workload you care about most.

Seed 1.6 is the reasoning model in the pair, while Grok 4 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 gives you the larger context window at 256K, compared with 128K for Grok 4.

Quick Verdict

Pick Grok 4 if you want the stronger benchmark profile. Seed 1.6 only becomes the better choice if instruction following is the priority or you need the larger 256K context window.
