Ray Flash 2
Ray Flash 2 is a video generation model from Luma Labs designed for fast video creation with configurable resolution, aspect ratio, and keyframe inputs.
Fast video generation with keyframe control
Ray Flash 2 is a video generation model developed by Luma Labs, released in 2025. It is designed to produce videos from text prompts and image inputs, with support for configurable duration, resolution, aspect ratio, and looping. The model is tagged as fast, indicating it is optimized for lower-latency generation compared to heavier video models in the Ray family.
Ray Flash 2 accepts both a start frame and an end frame as image inputs, allowing users to guide the visual content at the beginning and end of a generated clip. This keyframe-based control makes it well-suited for workflows that require consistent visual anchoring, such as animating between two specific images or creating looping video assets. The model supports a context window of 1000 tokens and is available directly through MindStudio without requiring separate API credentials.
