Ray 2

Ray 2 is a large-scale AI video generation model developed by Luma Labs, released in January 2025. It runs on approximately 10 times the compute of its predecessor, Ray 1.6, and is built on a multi-modal architecture trained directly on video sequences rather than individual frames. This training approach gives the model an understanding of natural motion, lighting behavior, and physical object interactions. Ray 2 accepts text prompts, images, or video as input and generates clips ranging from 5 to 9 seconds, extendable up to 30 seconds, at resolutions up to 1080p with optional 4K upscaling. Ray 2 supports multiple aspect ratios including 16:9, 9:16, 1:1, and 21:9, and includes keyframe control so users can define start frames, end frames, or both for precise scene direction. A speed-optimized variant called Ray 2 Flash delivers comparable visual quality in roughly one-third the render time, making it suitable for rapid iteration. The model is available through Luma AI's own platform and via Amazon Bedrock, where AWS serves as the exclusive cloud provider for fully managed access. It is used across industries including advertising, entertainment, architecture, fashion, film, and music production.

Capabilities

What Ray 2 supports

VID

Text-to-Video

Generates video clips from natural language text prompts. Outputs range from 5 to 9 seconds and can be extended up to 30 seconds.

IMG

Image-to-Video

Animates a provided image into a video clip, using the image as a visual starting point. Accepts image URLs as direct input.

AI

Keyframe Control

Allows users to specify start frames, end frames, or both to direct scene composition and transitions. Provides precise control over how a video begins and ends.

AI

High-Resolution Output

Renders video at up to 1080p natively with optional 4K upscaling. Supports aspect ratios of 16:9, 9:16, 1:1, and 21:9.

AI

Ray 2 Flash Variant

A speed-optimized version of Ray 2 that produces comparable visual quality in approximately one-third the standard render time. Designed for rapid prototyping and iterative workflows.

AI

Multi-Modal Input

Accepts text prompts, static images, and existing video clips as inputs within a single workflow. Enables flexible creative pipelines across different source material types.

API

Cloud API Access

Available through Amazon Bedrock as a fully managed API, with AWS serving as the exclusive cloud provider. No infrastructure setup is required to call the model.
