Anthropic Launches Claude Managed Agents Cloud Service, Cutting Enterprise Agent Development from Months to Weeks

Anthropic introduced Claude Managed Agents, a new cloud service that accelerates AI agent development by managing infrastructure and offering features including agent-to-agent task delegation and automated prompt refinement. The service reduces production-grade agent creation time from months to weeks, with early adopters including Notion, Rakuten, and Asana. A separate update to Claude 3.7 Sonnet also improved reliability and latency for tool use and function calling, reducing tool call error rates and adding parallel tool invocation support — changes live in both the Anthropic API and Amazon Bedrock with no model version change required. Developers on Hacker News reported 40-60% latency reductions in multi-step agentic pipelines during early testing of the parallel tool calling update.
