# LTX-Video — hosted API access

This repository is **not the model weights** — it documents running **LTX-Video** through a
hosted API on **[apimodels.app](https://apimodels.app)**, a multi-model gateway where one key and one
OpenAI-compatible endpoint reach 110+ image, video, audio and language models.

- Original model & weights: **https://huggingface.co/Lightricks/LTX-2.3**
- Authors: Lightricks
- License: LTX-Video Open Weights License (commercial use permitted under a revenue cap)

Independent hosted-API integration. Not affiliated with or endorsed by the authors; does not
redistribute their weights. All credit for the model is theirs.

## What it does
