Slides for My CEA-EDF-INRIA 2026 LLM Tutorials

I am giving two tutorials at the CEA-EDF-INRIA Computer Science School 2026, as part of the program on LLMs, software engineering, and formal methods. The slides are available here: Monday, 15:00-18:00 - Data Cleaning and Pretraining: download the slides Tuesday, 15:00-18:00 - LLMs and AI Safety: download the slides Monday: Data Cleaning and Pretraining This session follows the life of a model before it is “ready”: collecting data at scale, cleaning and filtering it, building diverse training mixtures, and using self-supervised learning for pretraining. We will also look at why source code is such a useful data modality for strengthening logical reasoning and structured problem solving in LLMs.
