Comparison with Other Models
vs Luma Ray 2: Ray Flash 2 is a distilled, faster variant of Luma Ray 2, offering up to three times faster video generation and costing less while retaining strong video realism. Ray 2 provides higher fidelity and supports more complex animations, but at slower speeds and higher resource usage.
vs Luma Ray 1.6: Compared to Luma Ray 1.6, Ray Flash 2 offers improved speed, much higher resolution (up to 720p), and better motion coherence. Ray 1.6 produces shorter, lower-resolution videos with less natural motion.
vs Synthesia: Ray Flash 2 excels in photorealistic video content creation with coherent scene dynamics, while Synthesia focuses on real-time avatar animations and lip-sync for interactive video content. Ray Flash 2 is more suitable for cinematic and complex video generation.
