Seed-2.0-Lite vs DeepSeek V3.1 (Reasoning)

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

Seed-2.0-Lite is clearly ahead on the aggregate, 63 to 41. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Seed-2.0-Lite's sharpest advantage is in multimodal & grounded, where it averages 79.6 against 41.5. The single biggest benchmark swing on the page is MMMU-Pro, 80 to 37.

DeepSeek V3.1 (Reasoning) is the reasoning model in the pair, while Seed-2.0-Lite 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-2.0-Lite gives you the larger context window at 256K, compared with 128K for DeepSeek V3.1 (Reasoning).

Quick Verdict

Pick Seed-2.0-Lite if you want the stronger benchmark profile. DeepSeek V3.1 (Reasoning) only becomes the better choice if you want the stronger reasoning-first profile.
