Overview / Description
Luma Uni 1.1 API is an AI image generation API from Luma Labs that developers call to produce and edit images inside their own apps and production pipelines. Uni-1.1 handles text-to-image and image-to-image editing, with text rendering, spatial reasoning, multi-panel output, and style transfer, plus a Uni-1-max variant for higher-quality output at roughly 2.5x the cost. It sits alongside Luma's Ray 3.2 video model in the same API surface, so teams building creative tooling can reach both image and video generation through one integration. Pricing is pay-per-image: at 2K resolution, text-to-image runs $0.0404–$0.1000 and image edits $0.0434–$0.1030, with reference images adding incremental cost. As an image generation API it targets developers and creative teams integrating generation into existing workflows, and Luma lists partners including Freepik, Envato, and Comfy. Scale Plans offer dedicated capacity with a four-unit minimum for higher-volume production, available through sales.
