LTX Video 2.0 Fast is the speed-optimized text-to-video endpoint within Lightricks' LTX-2 family, an open-source multimodal model line. Where the LTX Video 2.0 Full Quality and LTX Video 2.0 19B variants target maximum fidelity, the Fast variant prioritizes generation speed, making it suited to prototyping, batch generation, and high-volume iterative workflows where turnaround matters more than peak quality.

A defining trait of the LTX-2 family is unified, synchronized audio and video generation from a single model, so dialogue, ambience, and sound effects are produced together with the visuals rather than added in a separate step. Lightricks distributes the models as open source, publishing weights for the community to run and build on.

The LTX-2 family extends Lightricks' earlier LTX-Video work, with the 2.0 generation released in late 2024. Lightricks later shipped LTX Video 2.3 Fast and its Full Quality counterpart in 2026, continuing the open-source line as the newest releases in this family.
