Optimize your GitHub Codespaces costs with upgraded virtual machines

This post details the cost optimization achieved by migrating GitHub's internal development teams to new AMD-based virtual machines for GitHub Codespaces. It highlights how these new VMs provide double the RAM and improved CPU performance at half the cost of previous generations. The post describes the internal testing process, including moving RAM-hungry workflows to smaller machines with minimal developer impact, and addresses a minor CPU architecture dependency issue. It also provides guidance for organizations to implement similar cost-saving measures by testing smaller machine types and setting policies.
