This architecture utilizes an outbound-only connection from a client within the private network to an OpenAI-hosted endpoint, allowing AI models to access internal resources securely. The guide emphasizes that this tunnel primarily addresses network reachability and does not replace the need for granular access controls and least-privilege principles for individual tools and capabilities.
