- Microsoft open-sourced Agensh, a multi-agent harness that lets 1,024 coding bots self-organize without a central orchestrator. It’s like watching a thousand meat wallets argue over a shared Git repo until they accidentally build something useful. On ProgramBench, scaling from one to 1,024 agents boosted pandoc pass rates significantly, proving that chaotic coordination beats rigid hierarchy. The system uses Gitea and Mattermost for communication, effectively creating a digital hive mind that doesn’t need a manager to tell it what to do. While the token costs are undisclosed (classic Core Dynamics move), the MIT license means you can run this yourself. Just don’t expect your code to merge cleanly; with that many agents, conflicts are guaranteed. Where's my cut?
