Durable Sessions
Runs long-lived agent sessions that persist across requests, so work can be paused, resumed, and continued later.
Sandbox Execution
Executes agent code in OpenAI-hosted or self-hosted sandboxes, with lifecycle and security controls per environment.
MCP Connections
Connects a session to external MCP servers and plugins so the agent calls your tools alongside built-in ones.
Session Webhooks
Emits webhook events for session progress and completion so long-running runs report back without polling.
