Luma AI Launches Ray3: the world’s first “inference-capable” video model
Luma AI unveiled Ray3, a next-generation generative video model the company bills as the industry’s first inference-capable (what Luma frames as “reasoning”) video model — and the first to produce studio-grade High Dynamic Range (HDR) video natively, including exportable 10-, 12- and 16-bit ACES/EXR masters for professional pipelines.
Ray3 not only understands language and visual information but also evaluates its own generation results to ensure more accurate creative execution. It is also the first AI model capable of generating studio-quality HDR video, supporting up to 16-bit high dynamic range output for greater detail and color preservation.
What Ray3 promises
Ray3 is designed to bridge ideation and production. Rather than mapping a prompt straight to pixels, Luma describes Ray3 as breaking down a creative brief into steps (concept → shots → motion → lighting → render), generating intermediate notes/annotations and verifying spatial and temporal consistency at each step — effectively behaving like an automated creative partner during previsualization and rendering. That “reasoning” layer is central to Luma’s pitch: it lets the model fix problems, refine drafts, and produce more predictable, production-ready results.
Key technical claims include:
- Native HDR up to 16-bit (also supporting 10- and 12-bit workflows) with EXR export for VFX/post pipelines.
- The first AI to generate professional-grade HDR videos with rich colors.
- Ray3 is the world’s first “reasoning” video model, capable of understanding and thinking.
- Hi-Fi diffusion pass: a two-stage flow where fast, low-cost drafts are explored and the best takes are upgraded to 4K HDR “Hi-Fi” masters.
- Draft Mode for rapid ideation: Luma says drafts are up to 5× faster and 5× cheaper, enabling many more iterations before committing to a high-fidelity render.
- Visual annotation: creators can draw directly on a frame (arrows, sketches, marks) and Ray3 will interpret those scribbles into motion, camera blocking and choreography — without needing textual prompts.
- Advanced support for physical simulation, crowd/character consistency, realistic motion blur, interactive lighting and reflections, aimed at studio workflows.
Ray3 is Able to understand the creator’s intentions and construct complex scenes and actions step by step. Ray3 combines multimodal reasoning with production-grade output formats. Rather than just mapping prompts to pixels, the model can plan coherent scenes, drafts are self-judged and refined , and refine results during generation until they reach quality standards—functionality framed by Luma as “reasoning” or inference-capable video generation.
Ray3 delivers production-ready fidelity, supporting high-speed motion, structure preservation, physics simulation, scene exploration, complex crowd animation, interactive lighting, caustics, motion blur, realistic graphics, and detailed representation, providing video outputs ready for high-end creative production pipelines.
How it fits into real workflows
Luma positions Ray3 as studio-ready: native HDR and EXR export mean generated footage can be dropped into Nuke/Resolve/After Effects timelines for grading and compositing, while Draft Mode speeds up creative exploration before committing render budget to Hi-Fi masters. The model is available in Luma’s Dream Machine web and iOS apps, and Luma has announced partnerships that put Ray3 into other creative suites (Adobe Firefly integration was announced alongside Luma’s launch). Early coverage notes that clips of up to ~10 seconds are currently the practical output length used in demos.
The company also offers a Ray3 API and team/workspace features for studios that want batch generation, collaboration and integration into asset pipelines. Pricing tiers (including a free tier with limited drafts) are listed on Luma’s pricing pages.
Practical limits and questions to watch
- Clip length & complexity: current demos and partner writeups focus on very short cinematic clips (roughly up to ~10 seconds in some integrations), so longer, narrative scenes still require stitching and editorial work.
- Integration vs. control: while Ray3’s EXR/16-bit output is designed for post workflows, studios will want clear guardrails and deterministic control over assets (body/face consistency across takes, use of IP, source-material provenance). Coverage so far emphasizes impressive capability but flags the usual production QA needs.
- Ethical & legal considerations: as with other generative tools, adoption raises questions about training data, copyright, and how AI-generated assets are credited and licensed; these debates typically follow major launches and will influence how studios adopt Ray3. (Industry press is already covering commercial partnership terms and availability windows.)
Why this matters — the technical and creative breakthrough
Two capabilities set Ray3 apart from earlier text-to-video and generative video models:
- Studio-grade HDR output: prior models typically produced SDR or converted approximations; Ray3’s native 10/12/16-bit HDR generation and EXR export remove a major barrier to professional adoption by preserving extended color and luminance information needed for grading and VFX. That compatibility is what lets outputs move directly into high-end post pipelines.
- Inference/Reasoning for visual storytelling: Luma positions Ray3 as a model that can reason about scenes (planning motion, maintaining character and physics consistency, judging drafts and retrying), which increases the likelihood that a single generation will be production-usable. This reduces manual cleanup and speeds iteration for complex multi-step scenes.
Industry observers note the Adobe partnership as a meaningful sign that third-party creative platforms are ready to consume and surface higher-fidelity generative video models to large user bases. Early integrations in Firefly let a broader creative community experiment with Ray3 directly inside established design workflows.

Conclusion
Ray3 represents a clear push by Luma AI to move generative video from novelty demos into studio toolchains — combining a novel “reasoning” architecture (iterative planning and self-correction), rapid drafting workflows, and native 16-bit HDR output aimed at post-production. Its immediate availability on Dream Machine and integrations such as Adobe Firefly make it one of the more consequential generative video launches of 2025; whether it reshapes production habits will depend on clip length scaling, reliability on longer sequences, and how quickly studios incorporate it into existing VFX and editorial pipelines.
