Luma AI, the a16z-backed AI video and 3D model company, announced a new model called Ray3 Modify that lets creators edit existing footage by providing character reference images and start‑and‑end frames. The model preserves the original motion, timing, eye line and emotional delivery while allowing transformations such as costume changes, location swaps or full reshoots with AI. Ray3 Modify is available through Luma’s Dream Machine platform and follows a recent $900 million funding round led by the Public Investment Fund‑owned AI firm Humain. Ler mais

Luma AI has introduced Ray3, its first reasoning-based video generation model, now available to users. By allocating more computing time to analyze prompts, Ray3 can handle longer, more complex action sequences than typical AI video tools, which usually produce clips of five to ten seconds. The model includes a visual annotation interface that shows its decision‑making process, a draft mode that creates low‑resolution drafts in about 20 seconds, and the ability to upscale to high‑fidelity 16‑bit HDR video in two to five minutes. Ray3 joins a growing field of generative video tools from companies like Midjourney and Google’s Veo 3, while also raising ongoing concerns about AI‑generated media and artist lawsuits. Ler mais
