Seed-2.0-Lite vs Kimi K2.5

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

Seed-2.0-Lite has the cleaner overall profile here, landing at 63 versus 60. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

Seed-2.0-Lite's sharpest advantage is in multimodal & grounded, where it averages 79.6 against 64.6. The single biggest benchmark swing on the page is MMMU-Pro, 80 to 61. Kimi K2.5 does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.

Kimi K2.5 is also the more expensive model on tokens at $0.50 input / $2.80 output per 1M tokens, versus $0.25 input / $2.00 output per 1M tokens for Seed-2.0-Lite. Seed-2.0-Lite gives you the larger context window at 256K, compared with 128K for Kimi K2.5.

Quick Verdict

Pick Seed-2.0-Lite if you want the stronger benchmark profile. Kimi K2.5 only becomes the better choice if mathematics is the priority.
