Description
LTX-2 AI is an online AI video generation service built around the LTX-2 open-source model, which is released under the Apache 2.0 license. Users describe a video in natural language or upload a reference image, and the platform generates 4K-capable video at up to 50 FPS with native audio synchronization, including dialogue, ambient sounds, and background music matched to the visuals.

The workflow is three steps: describe the video or upload an image, let the AI generate a 4K video with synchronized audio, then download it in multiple formats or integrate via the API. Because LTX-2 is open-source, the model can also be run locally, deployed on cloud infrastructure, integrated with ComfyUI, or fine-tuned with LoRA adapters. Generated videos work across YouTube, TikTok, Instagram, and other platforms without extra conversion.
The service is credit-based, with a free tier offering starter and daily check-in credits and 15-day temporary storage. Paid plans (Basic 1,000 credits, Pro 2,000 credits, Max 5,000 credits) add priority processing, permanent asset storage while subscribed, a commercial license, and access to the platform's full model library. Failed generations refund their credits automatically. The operator states it is an independent service with no affiliation to LTX Group or Lightricks.
