LTX-2.5 Fast
Lightricks' fast video model — synchronized audio, first-to-last-frame control, and clips up to 20 seconds, at resolutions up to 4K.
LTX-2.5 Fast is a cloud video-generation model built by Lightricks. It produces short video clips from a text prompt, a starting image, or by interpolating between a first and last frame. Clips run up to 20s at 4k with a synchronized audio track. It also supports a selectable frame rate. It runs through Replicate and Runware using your own API key, from about $0.03 per second of output.
