ByteDance to Launch Seedance 2.1 Video Generation Model with 20% Quality Boost

ByteDance is preparing to launch Seedance 2.1, an upgraded AI video model.

The new version is said to deliver about 20% better output than Seedance 2.0, with stronger frame consistency and more realistic scene physics.

The improvements were shaped by creator feedback and are expected to roll into tools like CapCut.

The move underscores ByteDance’s push to compete more aggressively in the fast-growing AI video market.
