Anthropic adds dynamic workflows to Claude Managed Agents, up to 1,000 agents
Anthropic announced on October 9 that Claude Managed Agents now supports dynamic workflows, entering public beta: a lead agent writes a plan, distributes subtasks to sub-agents and merges their results, with up to 1,000 agents launched per execution (the documentation lists 64 concurrent threads and notes that limit may change). In an internal test, Anthropic hid 70 bugs in a 116,000-line codebase and said a single agent caught 14 to 27 per run while the dynamic workflow consistently found 66; the company also warns the workflows burn a lot of tokens and recommends starting small. Developers enable it by setting the multiagent type to "multiagent_20261001", or get started with "/claude-api managed-agents-onboard" in Claude Code. A Chinese report says Claude Code Projects also widened its beta to waitlisted Pro and Max users around the same time.
Multi-agent orchestration is becoming a productized platform feature, but whether the gains justify the token cost still needs testing on your own workloads.
