“OpenAI Updates Its Model Spec” by Zvi
The Model Spec is potentially OpenAI's most important document. It outlines what they aspire for the model to do, and how it should think. I’ve already covered a previous version in depth, so my strategy this time is to look at the diff. I had a Google Doc created for this purpose, and will be working from there. A bunch of things get moved around or reworded, often piecemeal. There are a lot of line edits, most of which are improvements. I’m focusing on what looks new and important. My main new critique is that many of the new examples do not carve reality at its joints, instead having overdetermined answers, and fail to teach the model or reader what the Spec wants them to do in actually difficult cases. Overall I see the new Model Spec as philosophically and practically similar to the old Model Spec. That is not a terrible place to be, as the old Model Spec was a solid document with many strong details. It also means this is a highly ‘optional’ post for those who do not have cause to dig into such weeds. Table of Contents Five Values.
