LTX-2.5 Fast is the speed-optimized variant of LTX-2.5, Lightricks' latest video generation model. It turns a text prompt into video up to 4K, in landscape, portrait or square, at cinematic frame rates, with an AI-generated audio track that matches the scene.
LTX-2.5 improves every stage of generation: a diffusion video decoder for higher pixel quality, finer detail in texture, faces and typography, stronger prompt adherence, and native multi-shot scenes. A single generation can produce several connected shots that keep character, scene, lighting, visual style and voice consistent across cuts.
