OpenAI's Shift from Openness to Proprietary Models

Matt Bornstein reflects on the early days of AI, where open-source models were the norm, citing OpenAI as an example that has since become less open. He contrasts this with the current landscape where many companies are adopting open-source solutions for their AI development.

Open source was the norm for AI models earlier on, right? I mean, we literally have this company called OpenAI, which, you know, it's become a little bit a joke, it's not as open as it once was, or not nearly as open as it once was.

The close source vendors won't give you the access to do this.
