By Luma AI
Uni-1.1 API is Luma’s developer API for Uni-1, a unified image-generation and editing model where reasoning and image generation run inside the same decoder-only autoregressive transformer rather than through separate stitched systems. Released on 05-05-2026, the API provides two main endpoints: Generate Image for text-to-image and reference-guided generation, and Modify Image for natural-language image editing such as changing backgrounds, lighting, composition, localized details, or reference aesthetics. It supports up to nine reference inputs per request, standard aspect ratios, PNG or JPEG output, Python and JavaScript/TypeScript SDKs, and is offered through Uni-1.1 and Uni-1.1 Max tiers for production creative workflows.
