LTX, the open world model company spun out of Lightricks, today released LTX-2.5, the newest version of its open-weights video and “world” model and it arrives natively integrated into ComfyUI, the node-based workflow tool that has become the de facto prototyping environment for open generative media, through a strategic day-one launch partnership between the two companies.
The model is available now as open weights on Hugging Face, inside ComfyUI, and through the LTX API for teams that want managed generation. It is free to use for organizations under $10 million in annual recurring revenue; larger companies negotiate a license. LTX says its models have passed 33 million downloads, making the LTX family the most-used “open world” model line on the market.
Ahead of the launch, VentureBeat spoke exclusively with LTX co-founder and CEO Zeev Farbman and ComfyUI co-founder and CEO Yoland Yan about the release, the partnership, and why both companies are betting that open weights — not closed APIs — will win the video and world model market.
“We’re trying to maintain the same efficiency and the inference speed that we’re known for, but constantly pushing the quality up,” Farbman said. “We are introducing many cool things in this release: multi-shot support, a diffusion decoder for better quality, new conditioning modes, better support for autoregressive models that are critical for real-time use cases and robotics.”
