Can you elaborate on what you mean that o3 pro is a GT? In particular I don't understand how to reconcile what you're saying that o3 pro is in some way fundamentally different from o3 (albeit based on o3) with this tweet:

> As o3-pro uses the same underlying model as o3, full safety details can be found in the o3 system card.

Yeah, I totally get the confusion here. Unfortunately I can't give the recipe behind our models, so there's going to be some irreducible blurriness here, but the following statements are all true:

- o3 pro is based on o3

- o3 pro uses the same underlying model as o3

- o3 pro is similar to o3, but is a distinct thing that's smarter and slower

- o3 pro is not o3 with longer reasoning

In my analogy, o3 pro vs o3 is more than just an input parameter (e.g., not just the accelerator input) but less than a full difference in model (e.g., Ford Mustang vs F150). It's in between, kind of like car trim with the same body but a stronger engine. Imperfect analogy, and I apologize if this doesn't feel like it adds any clarity. At the end of the day, it doesn't really matter how it works - what matters is if people find it worth using.
