AWS’s latest weekly rollout added Anthropic’s Claude Sonnet 5 on AWS and made Amazon WorkSpaces for AI agents generally available, expanding tools for coding, agent workflows and desktop app access.

OpenSearch also introduced a log-analytics engine with up to 4x better price-performance on AWS benchmarks, and SageMaker AI said container image caching can cut generative AI inference scale-out time by up to half.
AWS paired the launches with lifecycle changes dated June 30, moving several services to maintenance from July 30, 2026, including Amazon Kendra, Amazon Q Business and multiple SageMaker AI features.
The roundup underscores AWS’s current push to add AI and developer automation features while pruning older products and features across its cloud portfolio.
