Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Claude 4.1 Opus 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 4.1 Opus's sharpest advantage is in knowledge, where it averages 57.6 against 53.9. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 58 to 52. 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 4.1 Opus.
Pick Claude 4.1 Opus 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.
