Seed-2.0-Lite vs GPT-4o mini

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 52. 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 reasoning, where it averages 73 against 49.4. The single biggest benchmark swing on the page is LongBench v2, 76 to 49. GPT-4o mini does hit back in coding, 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 $0.15 input / $0.60 output per 1M tokens for GPT-4o mini. That is roughly 3.3x on output cost alone. Seed-2.0-Lite gives you the larger context window at 256K, compared with 128K for GPT-4o mini.

Quick Verdict

Pick Seed-2.0-Lite if you want the stronger benchmark profile. GPT-4o mini only becomes the better choice if coding is the priority or you want the cheaper token bill.
