LLMs Create Custom Worlds, But Can't See What They Build
Source: X
Andrej Karpathy identifies an asymmetry in large language models: they're advancing toward generative world-building (simulating entire environments, narratives, systems on demand) while remaining blind to their own outputs. This gap means LLMs can't validate coherence, catch contradictions, or audit whether generated content matches user intent without external verification tools—a constraint for applications requiring reliable, self-correcting systems. The bottleneck isn't generation anymore. It's closing the feedback loop so models can perceive, evaluate, and iteratively improve what they produce.
