Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Claude 4 Sonnet finishes one point ahead overall, 64 to 63. 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.
Claude 4 Sonnet's sharpest advantage is in knowledge, where it averages 56.8 against 53.9. The single biggest benchmark swing on the page is SWE-bench Verified, 51 to 45. Seed-2.0-Lite does hit back in instruction following, so the answer changes if that is the part of the workload you care about most.
Seed-2.0-Lite gives you the larger context window at 256K, compared with 200K for Claude 4 Sonnet.
Pick Claude 4 Sonnet if you want the stronger benchmark profile. Seed-2.0-Lite only becomes the better choice if instruction following is the priority or you need the larger 256K context window.
