ChatGPT has achieved tremendous success and is already transforming the daily routines of many professionals across various industries.

While countless articles highlight the "30 must-know commands," few delve into the actual workings of the technology behind ChatGPT. To understand it, it's essential to grasp three key concepts:

- Embeddings: These represent words and phrases numerically, allowing large language models like GPT to process natural language.
- Transformers: The core component of large language models. Using the attention mechanism, they can focus on semantically related words even when they appear distant from one another.
- RLHF (Reinforcement Learning with Human Feedback): This technique is employed to train models on extensive datasets of questions and answers with minimal human supervision.

In this talk, Emanuele Fabbiani from xtream will provide a concise yet thorough introduction to embeddings, transformers, and RLHF. He'll describe the technology powering ChatGPT, enabling the audience to harness the tool to its fullest potential.
