Claude Sonnet 4.6 improves on coding, computer use, long-context reasoning, agent planning, and knowledge work. The Managed Agents public beta is particularly significant - it offers a fully managed harness for running Claude as an autonomous agent with secure sandboxing, built-in tools, and server-sent event streaming.
The ant CLI is a new command-line client for faster API interaction and versioning of API resources in YAML files. Claude for Word completed Microsoft Office integration across Word, Excel, and PowerPoint. Claude Cowork is now generally available on macOS and Windows.
Founder Takeaway
Managed Agents in public beta means you can now ship autonomous Claude agents without building your own sandboxing and orchestration infrastructure.
