What changed
OpenAI's managed Agents API public beta now supports computer use in addition to multi-agent delegation, tool search, tool calling and context compaction. OpenAI and Amazon also introduced Bedrock Managed Agents that adapt the core service to run with AWS resources entirely inside AWS.
Why it matters
The API can now operate graphical software and run inside another cloud control plane, increasing the importance of identity, network, screen-data and approval boundaries.
What to do
Re-run the existing disposable canary with computer use and, if relevant, Bedrock. Test one allowed action, denied external write, hostile screen content, cross-account resource, interruption, credential revocation and rollback while retaining complete traces.
Caveat
The service remains a public beta without a general-availability stability commitment. Hosted execution and AWS placement do not prove application containment, permission correctness, data residency or reliable recovery.
