# LTXV Open Weights — what it permits, and which models carry it

1 of the 24 models in the AI Token Router catalogue is published under LTXV Open Weights: LTX-2.5. Whether your use is permitted is set by the licence document, which has to be read.

LTXV Open Weights is Lightricks' own licence rather than a standard open-source text, so what it permits is set by that document alone; what can be stated without reading it is that it allows third-party hosting, which is the condition for a model appearing in this catalogue at all.

Commercial use: **Read the text** — A publisher's own licence. It permits third-party hosting, which is why the model is catalogued at all; every other term is in the document.

## Permits

- Third-party hosting — the condition for a model appearing in this catalogue at all, since closed-weight models are never resold here

## Requires

- Read Lightricks' licence text before you ship
- Treat any acceptable-use policy it incorporates as part of the licence

## Restricts

- Not stated here. User thresholds, attribution requirements, derivative-naming rules, territorial limits and acceptable-use terms are all common in licences of this kind; whether LTXV Open Weights carries any of them is a question only its text answers

## Models under LTXV Open Weights

**Availability:** 7 of the 24 catalogued models are callable today. The rest are listed at their intended rate but no configured upstream serves them, so a request naming one returns `no available channel`. Every table below marks which is which.

| Model | Publisher | Exact licence string | Callable | Document |
| --- | --- | --- | --- | --- |

## Questions

### Can I use LTXV Open Weights models commercially?

That is set by Lightricks' licence document rather than by anything inferable from its name, so we will not answer it from the name. What can be stated is that it allows third-party hosting, which is the condition for a model appearing in this catalogue at all — closed-weight models are never resold here. This is a reference, not legal advice. It exists so you can arrive at your own counsel with a sharper question than whether you are allowed to use the model.

### What does LTXV Open Weights require me to do?

Read Lightricks' licence text before you ship. Treat any acceptable-use policy it incorporates as part of the licence. Nothing beyond that list is stated here, because nothing beyond it follows from what the catalogue records — the licence name.

### Which models under LTXV Open Weights can I call today?

None yet. The one LTXV Open Weights model in this catalogue is listed at an intended rate but not served by any configured upstream, so a request naming one returns no available channel. 7 of the 24 catalogued models are callable right now.

This is a reference, not legal advice. It exists so you can arrive at your own counsel with a sharper question than whether you are allowed to use the model.
