Google says Genie 3 world models start to break down after about a minute

Mar 11th 2026

At GDC, Google DeepMind showed that Genie 3 builds reactive frame-by-frame virtual worlds that remain consistent for about a minute, and stressed the tech is aimed at AGI and agent training rather than replacing traditional video games.

  • Genie 3 world models lose consistency after roughly one minute due to memory limits.
  • Earlier versions of the model could only stay consistent for a few seconds.
  • Genie 3 generates one frame at a time, acting more like a prompt-driven video than a persistent 3D game world.
  • DeepMind says the system is not meant to replace traditional games but could enable new game experiences while the team focuses on AGI and training agents.
  • Google also showcased SIMA 2, an agent that can play games, and observers warn the technology could face IP scrutiny and has already affected game industry stock prices.
