- Robotics & Physical AI: Generate synthetic training data and world-simulation environments for robotics perception and planning pipelines using self-hosted LTX models fine-tuned via LoRA.
- Real-time video generation: Leverage Diffusion Fidelity Rendering for latency-sensitive applications such as interactive media, live previsualization, or game engine integration.
- Compositing pipelines: Use HDR and alpha-channel video outputs to feed directly into VFX and post-production workflows.
- Multi-model API orchestration: Route generation tasks across LTX-native and partner models (Veo 3.1, FLUX.2 Pro, Kling, etc.) through a single API for A/B testing or task-specific model selection.
- ComfyUI workflow automation: Build node-based generation pipelines combining video, image, and audio models without custom API code.
- Domain-specific fine-tuning: Apply LoRA training on proprietary datasets for medical imaging simulation, gaming asset generation, or branded creative production.
- On-premises deployment: Self-host model weights for air-gapped or data-sensitive environments; free commercial licensing available under $10M ARR.
