LTX-2.5 is now available in ComfyUI
Blog post from Comfy
LTX-2.5, LTX’s latest open video-generation model, is available in ComfyUI at launch and is designed to run quickly on consumer GPUs while offering downloadable weights and fine-tuning support. The release introduces Diffusion Fidelity Rendering, which assigns more computation to visually complex scenes through structured latent generation, adaptive keyframes, and a pixel-diffusion rendering stage, alongside a new diffusion video decoder intended to improve faces, text, and fast-motion detail. It also supports native multi-shot video generation that maintains continuity across cuts, a custom Gemma 4 12B text encoder for longer and more detailed prompts, a lightweight prompt enhancer, and an experimental feature that automatically predicts clip duration. LTX-2.5 retains native 4K output, synchronized audio and video, and frame rates up to 50fps, and is offered as open-weight development and distilled models as well as hosted Fast and Pro Partner Node variants with differing resolution, duration, and frame-rate limits. Users can access it by updating ComfyUI or using Comfy Cloud, downloading the model weights, and loading supplied text-to-video, image-to-video, or related workflow templates.
