LTX inference recipes

LTX-2 from Lightricks generates video with synchronized audio. FastVideo maintains both a distilled four-GPU path and a base 1088p single-GPU path.

Setup

The generated commands expect a local clone:

git clone https://github.com/hao-ai-lab/FastVideo.git
cd FastVideo

Use Configuration for supported Python and CLI settings, Optimizations for attention and memory tradeoffs, and the support matrix for the supported model and optimization surface.

Troubleshooting
  • The distilled recipe is source-configured for four GPUs; running it on fewer GPUs is unverified and may fail during distributed setup.
  • Audio-less output usually means the base checkpoint resolved instead of the distilled LTX-2 checkpoint with audio; check the loaded model ID in the logs.
  • Gated or missing checkpoints: run huggingface-cli login and confirm you accepted the model's license on Hugging Face.
Evidence status

All recipes on this page are Source-backed: their commands, model IDs, and flags were validated against the checked-in FastVideo sources listed above (static validation). No runtime GPU validation is recorded for these recipes, so GPU model fit, memory use, throughput, and runtime duration are Unknown and deliberately not claimed. Runtime buttons show only the GPU counts configured in checked-in sources.
