LLM beliefs are geometric objects, study finds

Researchers have developed a new method to understand how large language models like Llama-3.2 encode and update their internal beliefs. The study reveals that these beliefs are represented as curved manifolds in the model's representation space, evolving as new information is processed through prompts. The findings suggest that traditional linear methods for intervening in these representations can cause unintended side effects, and propose geometry-aware techniques to maintain the integrity of the belief structures.
