Seed 2.0 Pro at a glance
Released on February 14, 2026, Seed 2.0 Pro is one of the 5 ByteDance Seed models tracked on this site. It is a closed model: you access it through an API, from ByteDance Seed or one of the 10 providers listed on models.dev. It has a reasoning mode: it can "think" before answering, which helps with multi-step problems but uses more tokens, and therefore more money. That makes it 8 months old as of October 22, 2026.
We file it under mid-range models (34 models in this category on the site).
What it costs
