Luma Launches Uni-1.1 API to Transform AI Image Creation and Editing

Luma AI on Tuesday opened access to its Uni-1.1 API, a new developer interface for its Unified Intelligence model that combines image generation and natural-language editing in a single system. The REST-based API, now available in two tiers, is designed to let developers build production workflows that generate and modify images using plain-language instructions.

The release builds on Luma’s Uni-1 model, introduced last month, which departs from the standard approach of using separate systems for text and images. Instead, the underlying model processes both modalities together, allowing it to interpret creative intent before producing output. Luma says this structure improves how the system handles multi-step instructions and maintains consistency across edits and references.

The Uni-1.1 API includes two primary endpoints: one for generating images from text or reference inputs, and another for editing images through natural-language commands. Developers can provide multiple reference images in a single request to preserve visual elements such as identity or style, while edits like lighting changes or background swaps can be described directly without structured prompts.

Luma said the API is already being used in production by partners including Envato, Krea, and Magnific, among others. The company also highlighted performance claims, including faster generation times and lower cost compared to similar systems, alongside benchmark rankings across image and reasoning tasks.

The launch positions the Uni-1.1 API as a tool for end-to-end creative workflows, where generation and editing happen within a single system rather than across multiple tools. By exposing the model through a standard API, Luma is targeting developers building applications that require consistent visual output across iterative or multi-step processes.

The Uni-1.1 API is available starting Tuesday with usage-based pricing and expanded support for higher-volume deployments, as Luma looks to broaden adoption of its unified model approach.
