Training and steering video models like LTX is the most viable way to align AI with real production needs, where predictability, ownership, and creative intent matter as much as visual quality"
FAQs
What is the LTX-2 API?
The LTX-2 API is a high-performance text-to-video generation interface powered by the LTX-2 model. It enables developers to generate HD and 4K video, set custom frame rates and durations, and integrate advanced AI video capabilities into production systems.
Does the LTX-2 API have a Playground for testing?
Yes. The LTX API Playground allows you to test prompts, explore resolution and FPS settings, and preview outputs before integrating the API into your stack.
What resolutions and FPS values does the LTX-2 API support?
Supported formats include:
- 1080p, 1440p, and 4K
- 25 or 50 FPS
- 6–20 second durations (depending on model: ltx-2-fast or ltx-2-pro)
This gives developers the flexibility to balance speed, fidelity, and output requirements.
Does the LTX-2 API support image-to-video generation?
Yes. The LTX API includes image-to-video functionality, allowing developers to animate static images or evolve concepts into dynamic sequences using LTX-2.
Where can I find LTX-2 API documentation?
You can access full documentation in the LTX Studio API Docs, which includes authentication details, request examples, model parameters, supported formats, and best practices for integrating the LTX-2 API into production workflows.
How much does the LTX-2 API cost?
LTX-2 API pricing varies based on usage volume, resolution, and performance tier. Current plans are available on the LTX pricing page, with custom options for enterprise or high-throughput deployments.
