Under the Hood: How OGX Enforces Guardrails Inside the Agentic Loop
· 10 min read
AI agents that call tools, search documents, and reason over multiple turns are powerful, but they also need boundaries. A model that can execute a web search or query your internal knowledge base should not be free to produce harmful content along the way.
OGX implements guardrails as a first-class feature of the Responses API.

This post explains exactly how that works, why the design choices matter, and how to use it in practice.
