Seed 1.6 vs DeepSeek V3.2

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

Seed 1.6 finishes one point ahead overall, 65 to 64. 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.

Seed 1.6's sharpest advantage is in multimodal & grounded, where it averages 79.6 against 66. The single biggest benchmark swing on the page is MMMU-Pro, 80 to 61. DeepSeek V3.2 does hit back in mathematics, 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 DeepSeek V3.2 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 DeepSeek V3.2.

Quick Verdict

Pick Seed 1.6 if you want the stronger benchmark profile. DeepSeek V3.2 only becomes the better choice if mathematics is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
