LTX exposes its capabilities through a REST API supporting video generation, world simulation, and multimodal outputs. Developers can integrate LTX's proprietary models (LTX-2.5, LTX-2.3, LTX-2, LTXV) or route requests to partner models (Veo 3.1, FLUX.2 Pro, Kling, Seedance, GPT Image, Nano Banana 2) through the same interface.
Integration touchpoints:
- ComfyUI — node-based workflow integration for visual pipeline builders
- HuggingFace — model weights and inference endpoints available on the Hub
- Fal — serverless GPU inference via the Fal platform
- ElevenLabs — audio generation pairing for video+audio pipelines
Self-hosting: Model weights are openly available, allowing deployment on private or on-premises infrastructure. Fine-tuning via LoRA is supported for adapting models to specific domains (robotics, medical imaging, gaming assets, etc.).
Output formats: HDR video, alpha-channel video (for compositing), and standard video formats are supported via Diffusion Fidelity Rendering.
Licensing: Free commercial use is available for organizations under $10M ARR. Enterprise licensing is available for larger organizations.
