AI Fundamentals

To understand the risks that artificial intelligence poses and to learn what measures we can take to mitigate them, it is essential to understand the technology itself: how it works, how it is used, and where its strengths and weaknesses lie.

Summary

To understand the risks that artificial intelligence (AI) poses and to learn what measures we can take to mitigate them, it is essential to understand the technology itself: how it works, how it is used, and where its strengths and weaknesses lie. We describe key concepts in machine learning (ML), the approach that powers most modern AI systems, with a particular focus on the technologies that power Large Language Models such as OpenAI's GPT-4 or Google's Gemini. We introduce the phenomenon of scaling laws, where AI systems' performance improves predictably as the amounts of data and computation used during their training are increased, and consider what this implies for future AI progress.
