## AI overview

GitHub describes how upgraded AMD-based Codespaces virtual machines provide more RAM and improved CPU performance, allowing development teams to use smaller machines at lower cost. Internal trials found that some teams could cut CPU counts in half while retaining the same RAM, with little developer impact and approximately 50% savings. A CPU architecture dependent build process required a simple QEMU configuration change.
