Create a Prediction
Send a POST request to create a new prediction. This will return a prediction ID that you'll use to check the result. The request should include your model inputs and API key.
Get Prediction Result
Poll the prediction endpoint with the prediction ID until the result is ready. The API uses long-polling, so you'll need to repeatedly check until you receive a success status.
Overview
The model "LTX-2" is developed by Lightricks, a pioneer in AI-driven content creation. It is not specifically an "image-to-video" model but rather a comprehensive AI video foundation model that integrates synchronized audio and video generation. LTX-2 is built on the DiT (Denoising Diffusion Transformer) architecture and offers extensive creative control with features like multi-keyframe conditioning, 3D camera logic, and LoRA fine-tuning. It supports various inputs, including text-to-video and image-to-video generation, making it versatile for different creative needs.
LTX-2 is unique because it provides a complete open-source solution for generating high-fidelity video with intrinsically linked audio, allowing for professional-grade video production at a lower cost and with greater efficiency. It can deliver native 4K resolution at up to 50 frames per second and supports sequences up to 10 seconds long. The model's open-source nature encourages collaboration and innovation within the AI community.
LTX-2's capabilities are designed to democratize video production, making it accessible to independent creators and enterprise teams alike. It runs efficiently on consumer-grade GPUs, reducing the need for extensive traditional resources and empowering users to produce professional-grade videos without enterprise infrastructure.
