Whichever the default free model is right now- I stopped paying for it when Gemini 2.5 came out in Google's AI lab.

4o, o4? I'm certain it wasn't 3.5

Sigh. This is a point in favor of not allowing free access to ChatGPT at all given that people are getting mad at GPT-4o-mini which is complete garbage for anything remotely complex... and garbage for most other things, too.

Just give 5 free queries of 4o/o3 or whatever and call it good.

If you're logged in, 4o, if you're not logged int, 4o-mini. Both don't score well on the benchmark!

This gets at the UX issue with AI right now. How's a normie supposed to know and understand this nuance?

Or a non-normie. Even while logged in, I had no idea what ChatGPT model it was using, since it doesn't label it. All the label says is "great for everyday tasks".

And as a non-normie, I obviously didn't take its analysis seriously, and compared it to Grok and Gemini 2.5. The latter was the best.

Might be worth trying again with Gemini 2.5. The reasoning models like that one are much better at health questions.

Gemini 2.5 in AI Studio gave by far the best analysis

I can’t believe you’re getting downvoted for answering the question about the next-token-predictor model you can’t recall using.

What is happening?
