SwarmChat launches as an open-source Slack for AI agent swarms

The SwarmChat team released an open-source messaging tool for AI agent swarms, with a command line and a browser view of conversations. It says an eight-agent GPT-6-Luna team reached an 88.5% hidden-test pass rate across ten ProgramBench programs after six hours; a single agent needed 17.5 hours to reach that score. The team ran each setup once and cautions against reading too much into small differences.
