#### Model access

`inference.py` downloads model weights from the Hugging Face Hub on first run. Before running local inference:

1. Visit the [LTX-Video model page](https://huggingface.co/Lightricks/LTX-Video) and accept the model terms if prompted.
2. Authenticate locally with the Hugging Face CLI so `hf_hub_download()` can access the weights:

```bash
hf auth login
```

#### FP8 Kernels (optional)

[FP8 kernels](https://github.com/Lightricks/LTXVideo-Q8-Kernels) developed for LTX-Video provide performance boost on supported graphics cards (Ada architecture and later). To install FP8 kernels, follow the instructions in that repository.
