   Coral AI Labs and academic collaborators introduce AgentRadio for asynchronous coordination among coding agents

   Researchers from Coral AI Labs and several universities presented AgentRadio, an asynchronous message-passing layer that lets multiple coding agents communicate during execution without pausing their primary work. In tests on the SWE-Atlas QnA benchmark, a four-agent setup using AgentRadio improved long-horizon codebase question accuracy over single-agent baselines and outperformed a single Claude Code agent running Claude Opus 4.8. The team also said the ideas are being adapted into a commercial product called Coral Code.
