Coral AI Labs, working alongside researchers at multiple universities, published a paper on July 30 introducing AgentRadio, an asynchronous message-passing layer that lets AI agents communicate between execution steps without pausing their primary workflows. The coordination gap in multi-agent systemsMost multi-agent AI architectures force agents to communicate at rigid checkpoints, like the end of a phase or during synchronized rounds. Four coordinating agents using a less powerful model outperformed a single agent using a stronger one. Open source and broader infrastructureCoral AI Labs released AgentRadio as open-source software under the Coral-Protocol organization on GitHub. The release fits into a broader ecosystem the organization is building, including CoralOS, a system designed for orchestrating AI agents at scale.
