Ltx 2
LTX-2 is the first DiT-based audio-video foundation model that contains all core capabilities of modern video generation in one model: synchronized audio and video, high fidelity, multiple performance modes, production-ready outputs, API access, and open access. Install the dependencies. The natten extra is the fastest backend for the diffusion video VAE below, and is Linux + CUDA only -- on Windows and macOS it is skipped automatically and decoding falls back to a Triton or eager implementation, so the same command works everywhere (see neighborhood attention backends) That is roughly 66 GiB. The CLI keeps the repository's folder layout under --local-dir, which is why the paths below include diffusionmodels/, vae/ and so on.
