LTX
Video generation API billed per second of output, with no request fees
LTX is the video generation API from Lightricks, built on the LTX-2 model family.
Endpoints cover text-to-video, image-to-video and audio-to-video, plus a retake endpoint that regenerates only part of an existing clip. Each model comes in a Fast variant for iteration and a Pro variant for higher fidelity.
Billing is per second of generated output, determined by duration, resolution and model, with no request or per-asset charges. LTX-2.5 Fast runs $0.09 per second at 720p, $0.13 at 1080p, $0.19 at 1440p and $0.30 at 4K; LTX-2.5 Pro is $0.12 at 720p and $0.17 at 1080p. The LTX-2 model weights are published on GitHub, though the hosted API is a commercial product.
