ByteDance launches new intelligent agent model Seed2.1

ByteDance has launched the Seed2.1 series of models, positioned as a new intelligent agent for real-world productivity scenarios. The model has made significant improvements in three dimensions: general agent capabilities, end-to-end code delivery, and multimodal understanding. It has achieved leading performance in multiple benchmark tests such as Workspace Bench, GDPval, and MobileWorld, and its win rate in coding scenario crowdsourcing testing exceeds that of Claude Opus 4.6.
