OmniGen
Unified open image generation model driven by arbitrary multimodal instructions.
About
OmniGen, introduced in September 2024, is a unified image generation model that takes arbitrary multimodal instructions — text plus reference images — and generates images directly, without the usual stack of add-on modules like ControlNet, IP-Adapters, or face-detection preprocessing. The authors frame it as a GPT-like paradigm for image generation: one model, any image task, finetunable on plain data.
Weights (Shitao/OmniGen-v1) and inference code are publicly released. The team is candid that limited resources leave room for improvement, and the exact license on the weights should be confirmed before commercial use.
