What LTX-Video is

LTX-Video Model Card This model card focuses on the model associated with the LTX-Video model, codebase available here. LTX-Video is the first DiT-based video generation model capable of generating high-quality videos in real-time. It produces 30 FPS videos at a 1216×704 resolution faster than they can be watched. Trained on a large-scale dataset of diverse videos, the model generates high-resolution videos with realistic and varied content. Image-to-video examples Models & Workflows Model Details - Developed by: Lightricks - Model type: Diffusion-based image-to-video generation model - Language(s): English Usage Direct use You can use the model for purposes under the license: - 2B version 0.9: license - 2B version 0.9.1 license - 2B version 0.9.5 license - 2B version 0.9.6-dev license - 2B version 0.9.6-distilled license - 13B version 0.9.7-dev license - 13B version 0.9.7-dev-fp8 license - 13B version 0.9.7-distilled license - 13B version 0.9.7-distilled-fp8 license - 13B version 0.9.7-distilled-lora128 license - 13B version 0.9.7-ICLoRA Depth license - 13B version 0.9.7-ICLoRA Pose license - 13B version 0.9.7-ICLoRA Canny license - Temporal upscaler version 0.9.7 license - Spatial upscaler version 0.9.7 license - 13B version 0.9.8-dev license - 13B version 0.9.8-dev-fp8 license - 13B version 0.9.8-distilled license - 13B version 0.9.8-distilled-fp8 license - 2B version 0.9.8-distilled license - 2B version 0.9.8-distilled-fp8 license - 13B version 0.9.8-ICLoRA detailer license - Temporal upscaler version 0.9.8 license - Spatial upscaler version 0.9.8 license General tips: The model works on resolutions that are divisible by 32 and number of frames that are divisible by 8 + 1 (e.g. 257). In case the resolution or number of frames are not divisible by 32 or 8 + 1, the input will be padded with -1 and then cropped to the desired resolution and number of frames. The model works best on resolutions under 720 x 1280 and number of frames below 257. Prompts should be in English. The more elaborate the better. Good prompt looks like The turquoise waves crash against the dark, jagged rocks of the shore, sending white foam spraying into the air. The scene is dominated by

Sizes & precisions

Open weights ship in several sizes and precisions. One page, all the variants — pick the one that fits your GPU. VRAM figures are estimates from model size.

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys ltx-video for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (ltx-video below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/videos/generations \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"ltx-video","prompt":"a drone shot over a forest"}'
