AgentRadio Research Enables Mid-Task Communication, Boosting Long-Horizon Task Resolution
import_jmr · x · 2026-08-21
A new study on long-horizon multi-agent systems (MAS) proposes AgentRadio, a mechanism allowing agents to communicate asynchronously during task execution, not just at phase boundaries. Experiments on a long-horizon code-comprehension benchmark show that four agents with mid-task communication (full AgentRadio) fully resolved 62.1% of tasks, significantly higher than single agents (32.3%) and four agents sharing only between phases (51.6%). However, this mid-course coordination increases API costs, with average spending rising from about $3 to roughly $19 per task.
