Q: What is Omni Gen 2 and what can it do for image editing

Omni Gen 2 is an open source image editor that can run offline and for free. It handles colorizing black and white photos, applying different art styles to images, swapping and editing backgrounds, and combining multiple reference images into new composite scenes. It works through text prompts to guide edits and can perform several rounds of changes while maintaining consistency with reference elements.

Q: How does Omni Gen 2 handle colorizing and style transfer

Colorizing is demonstrated by taking a black and white family photo and turning it into a colored scene with realistic skin tones and clothing, while style transfer turns the image into a different look such as Ghibli or Disney Pixar style.

This demonstrates multi image compositing while maintaining element appearance.
