Seed 1.6 Flash vs Seed-2.0-Mini

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

Seed 1.6 Flash has the cleaner overall profile here, landing at 56 versus 53. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

Seed 1.6 Flash's sharpest advantage is in agentic, where it averages 54.5 against 46.2. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 52 to 43.

Seed-2.0-Mini is also the more expensive model on tokens at $0.10 input / $0.40 output per 1M tokens, versus $0.08 input / $0.30 output per 1M tokens for Seed 1.6 Flash. Seed 1.6 Flash is the reasoning model in the pair, while Seed-2.0-Mini is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use.

Quick Verdict

Pick Seed 1.6 Flash if you want the stronger benchmark profile. Seed-2.0-Mini only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
