Seed-2.0-Lite vs GPT-4.1 nano

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 49. 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 mathematics, where it averages 75 against 9.8. The single biggest benchmark swing on the page is AIME 2024, 73 to 9.8. GPT-4.1 nano does hit back in reasoning, so the answer changes if that is the part of the workload you care about most.

Seed-2.0-Lite is also the more expensive model on tokens at $0.25 input / $2.00 output per 1M tokens, versus $0.10 input / $0.40 output per 1M tokens for GPT-4.1 nano. That is roughly 5.0x on output cost alone. GPT-4.1 nano gives you the larger context window at 1M, compared with 256K for Seed-2.0-Lite.

Quick Verdict

Pick Seed-2.0-Lite if you want the stronger benchmark profile. GPT-4.1 nano only becomes the better choice if reasoning is the priority or you want the cheaper token bill.
