Transformers need glasses! Information over-squashing in language tasks

Federico Barbero, Andrea Banino, Steven Kapturowski +5

We study how information propagates in decoder-only Transformers, which are the architectural backbone of most existing frontier large language models (LLMs). We rely on a theoreti…
