LTX is made by Lightricks, the company behind Facetune and Videoleap. The weights are open, so people run it locally too. On NeuralBox it runs in the browser.
LTX 2.3 Fast renders 6 to 20 seconds in 2-second steps, with a 10-second cap in 1440p and 4K. LTX 2.3 Pro renders 6 to 10 seconds and can add sound.
