World Models Unstacked: The Patchwork Simulators Redefining AI Agency

Forget monolithic miracles. AI's world models are gritty stacks of hacks, each patching a failure that scaling alone couldn't fix. This is the blueprint.

⚡ Key Takeaways

  • World models stack techniques: tokenize, predict dynamics, generate counterfactuals, optimize policies inside sims.
  • Compression via discrete latents unlocks long-horizon reasoning without compute explosion.
  • Mirrors video game engines—AI's catching up to 90s sim tech for agency.
