Luma Ray 3.2

Ray 3.2 is Luma AI’s reasoning video model. It generates short cinematic clips from a text prompt, a starting image, an ending image, or both — with native HDR and optional EXR export for professional production workflows.

What it does

• Text-to-video — describe a scene and get a 5s or 10s clip.
• Image-to-video — provide a start_image and/or end_image to anchor the generation.
• Resolutions — 540p, 720p, or 1080p.
• Aspect ratios — 9:16, 3:4, 1:1, 4:3, 16:9, 21:9.
• HDR output — set hdr: true for true high dynamic range output (720p and 1080p only).
• EXR export — set exr_export: true alongside hdr: true to get the ACES2065-1 EXR file used by professional color-grading workflows.
• Looping — set loop: true for seamless looping 5s clips.

Constraints

• 10s clips support text-to-video only — no start_image, end_image, or loop.
• HDR is only available at 720p and 1080p, and only for 5s clips.
• EXR export requires HDR.
• Start and end images must be hosted at a public URL.

Pricing

Pricing is per video, by resolution × dynamic range × duration. See the model page for the full table.
