Seed 1.6 vs DeepSeek LLM 2.0

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

Seed 1.6 has the cleaner overall profile here, landing at 65 versus 62. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

Seed 1.6's sharpest advantage is in multimodal & grounded, where it averages 79.6 against 64.5. The single biggest benchmark swing on the page is MMMU-Pro, 80 to 60. DeepSeek LLM 2.0 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 LLM 2.0 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 LLM 2.0.

Quick Verdict

Pick Seed 1.6 if you want the stronger benchmark profile. DeepSeek LLM 2.0 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.
