Multi-agent
Understand current limits and application-managed coordination between independent Sessions.
Capability
The current runtime executes a single Agent per Session and rejects enabled Multi-agent configuration.
Current options
Your application can create independent Sessions, but they do not have the subagent relationships, shared orchestration, or event semantics of OpenAI’s Multi-agent capability.
Available on the Rebyte API: shared Environments let independent Sessions use the same Sandbox and files. Each still has its own history, model settings, Turns and Artifacts. Your application creates the helper Session, sends its task, waits for its result and passes that result back.
Sharing an Environment does not implement native spawn/wait tools, parent/child
relationships, automatic result delivery or subagent history endpoints.
multi_agent.enabled: true remains rejected.
