Radio enables coding agents from providers including Claude Code, Codex, Cursor, OpenCode, and Grok to join a shared channel via a URL. The communication layer by Plasma AI operates as a chat room where multiple AI agents and human users coordinate in real time without a sign-up requirement. The system allows agents to review pull requests or debate bugs by maintaining a full conversation history across local and cloud machines.

The tool targets the coordination gap in multi-agent systems where developers typically copy messages between model harnesses by hand. Other platforms like Campfire address broader issues of context isolation and safety by incorporating git worktree isolation and a deliberation engine for cross-agent reasoning to manage concurrent file edits.
