Have you asked what the process and effort looks like to onboard OpenAI as a vendor? Ask questions to decompose the system to understand the system. Be curious, it will guide you to understanding.
I really was just curious about any interesting gotchas anyone else has run into. Historically, Microsoft is a balance between "this is great because it's already here, we just need to turn on a button to enable it" and the quality or reliability being not what we expected, to put it mildly. That and onboarding is a headache for external tools, but is often a tiny fraction of long-term maintenance so isn't necessarily the highest-weighted issue.
