Claude Sonnet 5.5 Lands on AWS GovCloud for Government Teams

AWS GovCloud (US) now has Claude Sonnet 5.5, the smarter and faster version of Anthropic's mid-tier model that crushes coding tasks and knowledge work while keeping your data locked down in AWS infrastructure. If you're already running Sonnet, this is a solid upgrade—better performance, lower costs per task, and all the compliance goodness you need for government work.
