YC F26's Acyclic Labs open-sources infra to run 10,000-agent swarms in one session

Acyclic Labs (YC F26) launched and open-sourced infrastructure that runs 10,000 agents efficiently in a single session, claiming to cut long-running agent tasks from hours to minutes. The founders argue more agents doesn't mean faster work — today's models can't split tasks or share state without stepping on each other. The release bundles SwarmBench (benchmarking agent coordination), RL environments for training it, and a runtime for thousands of concurrent agents. Their thesis: the next leap is coordination, not smarter single models.
