AISystem is an open course about AI systems and the full low-level technology stack behind AI, including AI chips, AI compilers, inference systems, and training frameworks. The course is also known as AI System (AISys). Newer large-model material is maintained separately in the AIFoundation project.

The README highlights goals such as understanding the complete computer-system architecture behind AI through practical problems and case studies, learning system design across the AI lifecycle, and exploring research that combines modern systems architecture with AI. It also introduces mainstream frameworks, platforms, and tools used to build AI systems.
