Claude multiagent workflows support up to 1,000 agents per run
Overview
Anthropic's ClaudeDevs account says Claude can now orchestrate multiagent workflows of up to 1,000 agents per run.
According to the announcement, users configure an agent with the multiagent type multiagent_20261001 and ask Claude to run a workflow, with Claude writing the plan and handling orchestration.
A separate ClaudeDevs post says dynamic workflows for Claude Managed Agents are now in public beta. In this design, a lead agent writes a plan that runs across many agents in phases and combines their results at the end. Testing Catalog, which reports the public beta expansion, describes the same setup and links a ClaudeDevs video. The posts describe the feature as built for demanding workloads but do not report any performance results.
