From AI video to real-world simulation: LTX goes independent

LTX spins out of Lightricks as an independent company led by Zeev Farbman, focusing on open physical world simulation models like its native 4K LTX-2.

LTX is spinning out of Lightricks to become an independent company, fully focused on open world models. The studio, previously known for its video generation models, is redefining itself around open foundation models designed to simulate physical reality: how objects move, how forces interact, how a scene evolves.

The pitch follows the ongoing shift in AI. After LLMs became the reasoning engines for software, LTX sees world models as the future general-purpose engine for simulating reality, equipped with an understanding of physics. The target applications are broad: cinema and VFX, video games, warehouse robotics that rehearse trajectories in a simulated factory, autonomous vehicles replaying scenarios too dangerous to stage in real life, or buildings tested against an earthquake before the first shovel breaks ground.

The choice of openness distinguishes the company, where most of the sector builds closed systems: it wants to let its customers run, fine-tune, and extend its models on their own hardware, including at the edge. On the product front, the publisher claims for its LTX-2 model native 4K output, synchronized audio and video, and up to 50 fps, for about one-eighth the cost and one-tenth the rendering time of comparable models.

Organizationally, LTX remains led by its co-founder and CEO Zeev Farbman and its founding team. Lightricks continues its consumer applications, including Facetune, under the direction of Asaf Porat, the new General Manager. A dedicated program for physical AI developers accompanies the opening.
