If you do the same thing with Claude, it will tell you it's ChatGPT. The models are all being trained on each other's output, giving them a bit of an identity crisis.

One report is an anecdote, but I wouldn't be surprised if we heard more of this. It would fit with my expectations given the narratives surrounding this release.

I'm not sure what you're suggesting here, but the local versions you can download and run kind of show it's its own thing. I think it was trained on some synthetic data from OpenAI and have also seen reports of it identifying itself as GPT4-o too.
