Luma AI unveiled Ray3 Modify on December 18, 2025 — a groundbreaking upgrade to Dream Machine that finally solves AI video's biggest pain: transforming real actor footage with wild scene changes, costume swaps, or even character redesigns, all while preserving original motion, timing, eye lines, and emotional delivery. Powered by precise keyframe controls, character reference locking, and scene-aware fidelity, it turns "shoot once, reimagine forever" into reality. Early adopters are already slashing reshoots by 90%, calling it the hybrid-AI workflow that blends human authenticity with generative magic.

Luma AI, the breakout star behind Ray3 video generation, just inked a $900 million Series C on November 19, 2025 — led by Saudi powerhouse HUMAIN (PIF-backed), with heavy hits from AMD Ventures and a16z. The war chest unlocks exclusive access to Project Halo, HUMAIN's beastly 2-gigawatt AI supercluster in Saudi Arabia, set to go live Q1 2026 and rival xAI's Colossus in raw scale. Valued at $4B+, this isn't just cash — it's a geopolitical compute coup positioning Luma to train world-modeling AGI from video floods, leaving OpenAI and Google scrambling in the multimodal dust.
