EPISODE DESCRIPTION
Vishal Misra returns to explain his latest research on how LLMs actually work under the hood. He walks through experiments showing that transformers update their predictions in a precise, mathematically predictable way as they process new information, explains why this still doesn't mean they're conscious, and describes what's actually required for AGI: the ability to keep learning after training and the move from pattern matching to understanding cause and effect.

EPISODE SUMMARY
In this episode of a16z, featuring Vishal Misra and Erik Torenberg, Why Scale Will Not Solve AGI | Vishal Misra - The a16z Show explores LLMs do Bayesian inference, but lack plasticity and causality for AGI Misra models an LLM as an astronomically large, sparse matrix mapping every possible prompt to a probability distribution over next tokens, with training learning a compressed approximation of this matrix.
