Seems obvious to me that the quality of the models is not improving since GPT-4. The departures I’m guessing are a problem talent has with ‘founder mode’, Altman’s choice of fast pace, this absence of model improvement with these new releases, and the relative temptation of personal profit outside of OpenAI’s not-for-profit business model. People think they can do better in control themselves. I suspect they are all under siege with juicy offers of funding and opportunities. Whether or not they will do better is another story. My money is on Altman, I think he is right on the dumpster rocket idea, but it’s very difficult to see that when you’re a rocket scientist.
