I've been hearing mixed reviews about the different models out there. Can someone clarify for me which one is newer and more advanced: is it 4o or o3? I've read that 4o is supposed to be an improved model overall. For example, if I were to upload an STL file of something like a bridge to analyze its design and whether it can handle the expected loads, which model would be the better choice for that task?

I can’t tell if you’re serious, but testing structural load with AI seems a bit far-fetched. Are you sure this isn’t a homework scenario?
If you’re unsure, remember there’s actually a help button in the model selection section. It leads to info explaining each model, which could clear things up for you.
So, just to clarify, there actually isn’t a 3o; it’s o3. The models starting with oX are reasoning models, while 4o is more of a general-purpose model, much like GPT-4.1. By the way, 4o has been around a bit longer now, but it's still a solid choice for most tasks. You might want to check out o3 and o4-mini too, as they’re the newer ones right now.
4o is still my go-to for everyday tasks.
From what I've gathered, o3 is definitely the more advanced choice right now. If your project is about analyzing complex structures like a bridge, it might be the way to go.
Thanks for pointing that out! Sounds like I should be looking at o3 for something cutting-edge.
