Luma's Uni 1 image model from the Luma Agents API. Generates 2K-resolution images from text, or edits an existing image with natural-language instructions — background replacement, object modification, lighting changes, style transfer — while preserving the parts you don't mention. Up to 8 reference images guide style and content in either mode, web search grounds prompts that mention real-world subjects, and a manga style preset is included. Uni 1 Max is a drop-in higher-quality variant.
