What I was meaning was that ChatGPT is not a foundation model since it's been fine-tuned. Although the definition in the link is sufficiently broad you could choose to include it. I can't tell from the OpenAI docs whether it's possible to access GPT-4 without the ChatGPT fine-tuning. If so, that'd make this result more meaningful. Otherwise, I just don't think you can draw any great conclusions from this.
