Lewis Tunstall announced on X that the recording of his CERN lecture on training large language models is now online. The Hugging Face research engineer included access to the slides from the event and recommended watching the video at double speed due to his speaking pace. Tunstall focuses on LLM post-training, MLOps, and open-source tools in his role. The CERN presentation materials have been made available following the talk for those interested in the session content.
