LTX-2.5

Video and audio come out of LTX-2.5 together: Lightricks' 22B parameter generator produces footage with synchronized sound from text, image, or video conditioning, and its multishot mode holds character identity and visual style stable across consecutive scenes. The 2026 release ships as a full trainable transformer plus a faster distilled variant, with int8 and NVFP4 quantizations, a choice of two VAEs trading quality against speed, and FP8 casting with CPU offload for constrained GPUs; generation runs at 24 fps in clips of up to 121 frames or more per pass. Official workflow templates land in ComfyUI on day one, which has made the LTX line a staple of the open video community, and the stack expects Python 3.12, CUDA 12.7, and PyTorch 2.7. Weights are distributed under the LTX-2 Community License Agreement: commercial use is free for organizations under 10 million dollars in annual revenue, with paid licensing above that line, so hobbyists and small studios run it without cost while large companies negotiate terms.
