LTX 2

Turn a text prompt into 4K video with synced audio using LTX 2, an open-source AI video generator released under the MIT License.

The MIT License means you can read the code, modify it and build it into your own products.

LTX 2 is also built API-first, so developers can call it from their own apps and run batch jobs rather than clicking through a web editor.

Output is described as native 4K, with 10-bit color and 60 FPS, and all export formats are supported.

Audio and video are generated in sync, which saves a separate dubbing or sound pass.

Documentation is available, and the project leans on its community for support.

A free tier exists and does not ask for a credit card, so you can test the quality before committing any engineering time.

Image-to-video is still marked as coming soon, so for now the text-to-video route is the one to plan around.

Claims like speed and production readiness are the maker's own, so check them on your own footage.
