Luma AI: Photon

Q: Is the Photon API free for developers?

Photon is free to integrate using the Puter.js AI API . With the User-Pays Model , you can add AI to your app for $0, since users cover their own AI usage through their Puter account.

Model Card

Photon is Luma AI's flagship text-to-image model, launched in November 2024 alongside the Dream Machine platform. Luma built it on a proprietary Universal Transformer architecture rather than the diffusion process most image generators rely on, and says the design brings a large context window to image generation, letting the model take in multiple reference images and detailed instructions at once.

The model is built around character consistency, producing a consistent character from a single reference image and placing it into new scenes. It accepts up to four reference images for style, composition, or character guidance, and supports iterative editing through natural language prompts rather than manual masking.

Luma positions Photon for designers, filmmakers, architects, and other visual creators who need photorealistic, production-quality output with strong prompt adherence, and reports it as faster to run than comparable diffusion-based models in its own testing.

Photon Flash

Photon Flash is the faster variant of Luma AI's Photon image model, built on the same Universal Transformer architecture rather than diffusion. It's priced lower per image than Photon here, and Luma positions it as the speed-optimized option in the Photon family rather than a stripped-down one. It keeps Photon's core feature set: character consistency from a single reference image, support for up to four reference images for style and composition, and natural-language prompt-based editing. Luma describes Flash as built for the same creative workflows as Photon, trading some of Photon's generation time for lower latency and cost. That tradeoff suits high-volume or latency-sensitive use, such as rapid prototyping, iterative ideation, and applications that generate many images per session, where turnaround time matters more than squeezing out the last increment of output refinement.
