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.
