Kfir Aberman (Decart AI): Real-Time World Models & Lucy

Decart founding member and US officer Kfir Aberman traces the company from CUDA-kernel optimization startup to real-time video models — Oasis, and now Lucy — explaining the viral demos where users paint slime, fire, and hair changes onto live video. He shares company details (~100 people across Israel, San Francisco, and New York; $300M raised at a ~$4B valuation), defines world models as systems that imitate the physical world so robots can be trained on real physics, and argues the industry's biggest battle is now making models cheaper, which ties back to Decart's optimization stack.
