Lightricks’ 22B open-weights video model (August 2026): 10-second 720p image-to-video in seconds on datacentre GPUs, 4K HDR, native multishot, runs quantised on a 24–32 GB card. No built-in filter; NSFW LoRAs from LTX-2.3 carry over.

LTX-2.5 is Lightricks’ open-weights video world model, released 11 August 2026 with weights on Hugging Face under a permissive licence (free below $10M ARR) and day-one ComfyUI support. It is a 22B diffusion transformer with a Gemma 4 12B text encoder, a new diffusion video decoder for sharper faces and motion, native multishot generation and up to 4K HDR output. Because the weights are open there is no vendor filter, and community NSFW LoRAs trained for LTX-2.3 run on 2.5 without changes.
