What is Luma AI Ray2?
Ray2, Luma AI’s video generation model, launched on Dream Machine in 2025. It is part of the same Dream Machine that first put Luma AI on the map. It turns text prompts into short videos. Luma’s Ray2 guide lists 5- or 10-second clips and 540p, 720p, or 1080p output.
How to Use Ray2
Ray2 is available through Dream Machine. Log in, enter a text prompt, select Ray2, and choose a 5- or 10-second clip. Select a resolution, generate the video, then download it. Luma says generation can take about 10-60 seconds, depending on complexity.
Benefits for Creators
Creators can use Ray2 to make short clips for ads, lessons, storyboards, and film projects. For example, a creator could generate a 10-second city-at-dawn clip for an ad. They could then revise the prompt, or instruction, to change the scene.
