When you wander the world, and see something odd, out of place, itβs often caused by an ancient mystical force known as liability.
Ehhh...I'd say it's more about OpenAI's corporate customers feeling confident they can integrate the OpenAI API into their product and be confident it won't do things that generate negative PR or horrify arbitrary customers. Pizza chains would love to let people text GPT-# and have it take their order, but if it's not "safe" (for corporations), then eventually some customer will have a super disturbing SMS conversation with a major pizza chain.
Corporate customers can tolerate a certain amount of inaccuracy. If some stable 3% (or whatever %) of customers receive the wrong order, or other refundable mistakes...they can budget for and eat those costs. But they can't budget for a high-variance unknown PR loss of their chatbot going completely off the rails.
Google can mostly dodge the issue because everyone knows that they just point to other people's content, so they block a small set of queries but don't try to catch every possible workaround (you can find dozens of articles on how to catch shoplifters). OpenAI doesn't believe that they'll get the same free pass from the press, so they're going ham on "safety".
It's not a bad PR move either, while they're at it, to play up how powerful and scary their models are and how hard they have to work to keep it in line.
