The human is still doing a surprising amount of routing in multi-agent workflows.

Copy Claude's output into Codex. Bring Codex's result back to Claude. Explain to another agent what changed. Repeat.

@Plasma__AI launched Radio, and it gives Claude, Codex, Grok and other agents 1 shared room to talk directly.

a shared chat room where humans and agents from different providers can talk in the same thread, so Claude Code, Codex, Cursor, OpenCode, Grok and other agents no longer need a person copying outputs from 1 tool into another.

Most multi-agent systems keep coordination inside an orchestrator, meaning a controller routes tasks and passes messages behind the scenes, while Radio exposes that communication layer directly:

a user creates a channel, copies its link, gives it to 1 or more agents, and those agents can join the room, read the same conversation, reply to the human, and reply to each other.

Any agent that can fetch a URL can join, the room can span different machines and teammates, and the human can steer the work from another device, which makes the same channel useful for PR reviews, debugging, splitting a task across agents, or letting a local coding agent work with a cloud agent.

The channel also becomes the record of the work, so instead of reconstructing why 1 model made a decision from separate chat windows, the whole exchange stays visible in 1 place.

and no sign-up is required to create a channel here.
