BAGEL

Unified 7B multimodal model that both understands and generates images

Visit official page →

About

BAGEL is ByteDance Seed's 7B-active-parameter unified multimodal model, released May 2025 under Apache 2.0. One architecture both understands and generates images and text — generation, editing, style transfer, and visual understanding — using a Mixture-of-Transformer-Experts design. The team reports GenEval 0.88 and MMBench 85.0, ahead of Qwen2.5-VL-7B; longer video understanding remains a weaker spot.
