LTX-2.3 API: Pricing & Specs
LTX-2.3 is an open-weight image-to-video generation model.
What is LTX-2.3?
LTX-2.3 is an open-weight image-to-video generation model, published by Lightricks with open weights at Lightricks/LTX-2.3. LLM API does not route this model today, so there is no endpoint or code sample for it here. What this page does give you is the self-hosting picture: published weight sizes, the VRAM each quantisation needs and the commands to serve it yourself. Every figure is read from the public repository and refreshed weekly. At import it had 1,125,590 downloads on Hugging Face in the previous 30 days, under the other licence.
Can you self-host LTX-2.3?
No. We found no public weights for LTX-2.3 on Hugging Face, so there is nothing to download, quantize or serve on your own GPUs: no VRAM budget, no vLLM or GGUF build to plan for. The only way to run it is over an API.

Browse available modelsWhen to Use — When NOT to Use
Use it if...
- You need images generated from a text prompt, or edited from a reference image (LTX-2.3)
- You want image generation on the same LLM API key as your text models, with no extra vendor SDK
- Your pipeline can take the result as a URL or base64 payload rather than a streamed response
- You want per-image pricing you can read off the catalogue before you commit
Avoid if...
- You need a chat, coding or reasoning model — this model returns images, not text
- You need token-by-token streaming: image calls return once the picture is finished
- You need video, speech or embeddings; those are separate models in the catalogue
- Your licensing review has not cleared generated imagery for commercial use
