LTX releases open-weights LTX-2.5 video world model with robotics checkpoint

LTX-2.5 is available as open weights on Hugging Face, with native ComfyUI support and an LTX API option for managed deployment.
LTX rebuilt the generation pipeline with native multishot generation to keep characters, scenes, and voices consistent across cuts in a generated sequence.
The model uses a custom Gemma 4 language backbone and prompt enhancer for multi-subject prompts, plus a diffusion video decoder intended to reduce artifacts in high-motion video.
Diffusion Fidelity Rendering builds motion in an 8x temporally compressed latent space while allocating higher-fidelity keyframes according to scene complexity and available compute.
LTX-2.5 includes a pretrained physical AI and robotics checkpoint for domain fine-tuning, and LTX worked with Nvidia to reduce local-inference memory use on RTX GPUs and DGX Spark systems.
