This workshop introduces AI Infrastructure and Services at CSCS, the Swiss National Supercomputing Centre, and the Swiss AI Factory Antenna, HEARTS. In particular, this workshop considers AI infrastructure as an end-to-end system rather than a collection of isolated stages. It connects large-scale pre-training with reinforcement learning, model adaptation, evaluation, deployment, and specialized inference services that translate computational scale into daily impact.

- Jonathan Coles, on the engineering challenges of pre-training large models

- Elia Palme, on the fine-tuning approaches on HPC

- Dino Conciatore, on the inference for science services

- Sebastian Keller, on using coding agents for scientific computing
