# Microsoft open-sources Agensh, a leaderless harness for up to 1,024 agents

*2026-10-25 · Source: [MarkTechPost](https://www.marktechpost.com/2026/10/24/microsoft-agensh-multi-agent-harness-1024-agents/)*

Microsoft Research released Agensh, a multi-agent harness with no central orchestrator. Self-organizing workers share a Git repo, chat and a findings board, and it scaled from 1 to 1,024 agents on ProgramBench under a 6-hour budget.

**Why it matters:** It tests the opposite design to central orchestration, with coordination emerging through shared artifacts. Together with Anthropic's single-agent advice, it shows the field has not settled how agent work should be structured at scale.

**Topics:** agents, open source
