Dropped from the LTX API in August 2026, so it is mainly for researchers running the open weights locally.

Kenning's take

What it does

LTX-2 is an open-source video model from Lightricks that generates video and matching sound together, at up to native 4K and 50 frames per second, in clips of around 10 seconds, on consumer graphics cards. It was announced in October 2025 and its full weights were released in January 2026. It has since been replaced by LTX-2.3 and LTX-2.5: the LTX API stopped serving LTX-2 on 15 August 2026, but the weights remain on Hugging Face.

• Synchronised audio and video generation
• Native 4K at up to 50 fps
• About 10-second clips
• Camera, depth and pose control
• LoRA training support

Who it suits. Developers and researchers who want to run or study an earlier open video model locally.
