Luma Ray 3
Luma's Ray 3 was the first video model sold on reasoning and studio-grade HDR. It has since grown into a family: Ray3 Modify for editing, Ray3.14 for native 1080p at lower cost, and Ray3.2 with keyframe control. Here is what each version does, where to run it, and what to use in LazyKiwi today. Specs: up to 360p to 1080p; native 1080p since Ray3.14.
Using it
How to use Luma Ray 3
Ray 3 is a Luma product; LazyKiwi does not run it. These are the routes Luma offers.
Luma web app
Pick Ray3.2 as the model, write a prompt or upload a still, choose 5 or 10 seconds and a resolution, and generate. Draft Mode is the cheap first pass.
Luma API
Ray3.2 is exposed through Luma's API with credit pricing by resolution, duration and task; HDR and EXR cost more per clip.

What it is
What Luma Ray 3 is built for
Luma AI launched Ray3 on September 18, 2025 as "the world's first reasoning video model and the first to generate high fidelity 16 bit HDR". The pitch is studio work: the model reasons about the prompt, checks its own output, and renders in a colour range that survives a professional grade.
Reasoning
A model that plans and judges its shots
Luma describes Ray3 as reasoning-driven: it is meant to "understand intent, think by generating visuals and concepts, and judge its outputs" before returning a clip, which is why it is sold to film and games teams rather than to meme makers.
- Reasoning-driven generation
- Draft Mode: 5x faster, 5x cheaper
- Built with entertainment and gaming creatives
HDR
Native 16-bit HDR and EXR export
Ray3 generates in high dynamic range natively and exports 16-bit EXR frames, so the footage can go into a colour pipeline instead of being a finished SDR MP4. In Ray3.2, HDR costs twice the base credits and HDR with EXR three times.
- 16-bit HDR colour generated by the model
- EXR export in ACES2065-1
- Meant for grading, not just posting

What does "reasoning video model" mean?
Luma says the model understands the intent of a prompt, thinks by generating visuals and concepts, and judges its own outputs before returning a clip, instead of rendering the first thing that matches the words.

Is Ray 3 free?
Luma sells generations by credits in its app and API; the pricing table varies by resolution, duration and task, and Draft Mode is the cheaper pass. Check Luma's own pricing page for current numbers.
Can I use Ray 3 in LazyKiwi?
No. LazyKiwi does not run Luma models. For cinematic clips in the browser, use Veo 3 or Kling v3 Omni in the video generator, which start with free credits.
Ray 3 or Ray3: which is the right name?
