OmniGen2 is an open-source unified multimodal generation model supporting text-to-image generation, instruction-guided image editing, and in-context generation, released with training code, datasets, and a benchmark. It also ships EditScore, a family of reward models for evaluating and improving instruction-guided image editing via reinforcement learning.

Use cases

• generate images from text prompts
• edit images with natural language instructions
• fine-tune an image generation model on custom data
• run a unified multimodal image generation model locally
• evaluate image editing quality with a reward model
• use an image editing model in ComfyUI workflows

When to choose

• you need an open-source, Apache-2.0 licensed model for both text-to-image generation and instruction-based editing
• you want to fine-tune or do RL on an image editing model with released training code and datasets
• you want ComfyUI integration or inference speedups like TeaCache and TaylorSeer

When to avoid

• you need production-grade image generation without GPU hardware
• you only need simple image manipulation like cropping or filtering rather than generative editing
• you need video or audio generation
