World Models

“World model” is the most elastic label on this beat. RCTV’s May 21 flagship set the adjudication frame — what a lab claims a model does versus what it has shown doing — and the June 8 roundup caught NVIDIA, Runway and Luma reaching for the term in one week with very different evidence behind it. By September 2026 the label covered Runway’s interface-generating Solaris, its video-generating GWM Worlds 2, and World Labs’ camera-controlled Atlas inside four days. Pieces here read the claim against the artifact. See the AI Video Stack for the current state of each vendor.
