Seed 1.6 vs Llama 4 Behemoth

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

Seed 1.6 is clearly ahead on the aggregate, 65 to 40. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Seed 1.6's sharpest advantage is in coding, where it averages 42.4 against 14.1. The single biggest benchmark swing on the page is MRCRv2, 78 to 46.

Seed 1.6 is the reasoning model in the pair, while Llama 4 Behemoth 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 32K for Llama 4 Behemoth.

Quick Verdict

Pick Seed 1.6 if you want the stronger benchmark profile. Llama 4 Behemoth only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
