## Description

Recent studies in 2024 have revolutionised our understanding of large language models (LLMs). 

This talk explores three key discoveries. 

First, research shows Llama 2 models use English as their internal representation regardless of input/output language, explaining certain biases. 

Second, breakthroughs by Anthropic and OpenAI have revealed monosemantic features in Claude 3 and GPT-4, enabling better understanding and adjustment of topic-specific behaviours. 

Third, studies demonstrate why LLMs memorise outlier data, particularly unique strings and personal information, explaining instances of privacy breaches. We'll discuss implications for LLM privacy and security.

Attendees will walk away with a deeper understanding of the inner workings of LLMs, and with hints to mitigate their intrinsic limitations.
