LTX-2.5 under scrutiny: CTO Yaron Inger on whether open-weights video models really understand the world
kimmonismus · x · 2026-09-02
kimmonismus and Peter sit down with LTX co-founder and CTO Yaron Inger to stress-test the claims around LTX-2.5, the company's new open-weights video and world model:
- Video companies now claim their models "understand the world" rather than just generate clips — this interview probes what that actually means;
- Whether the model's physics are good enough for robotics, and what native multi-shot generation truly remembers across cuts;
- Whether speed benchmarks are fair, and what creators can expect on affordable hardware;
- How LTX plans to build a business when weights are freely downloadable.
Framed not as a product demo but as a discussion of whether AI video becomes genuine infrastructure for filmmaking, simulation, and physical AI.
