Quick answer
LTX is Lightricks' family of video models. LTX-2 (announced October 2025, fully open-sourced in January 2026) generates synchronised audio and video; LTX-2.3 (March 2026) added a redesigned VAE and native portrait up to 1080×1920; LTX-2.5 (August 2026) added multi-shot with a consistent character and voice. The full model needs an 80 GB+ GPU to run locally. In Kenerate's studio you can run LTX 2.5 (5–20 s, up to 4K, start and end frames), LTX 2.3 (5–20 s, up to 1080p, extend) and LTX 2 — no GPU. The clips here are real LTX 2.3 outputs.
