OpenAI’s Model Lineup Is Confusing, Anyone Else Lost?

I’m a little confused about when to use which model in the ChatGPT interface. Currently, we have ChatGPT 4o, 4o mini, o1, and o3 mini.
When would o1 be a better choice than o3 mini?
What kind of prompts make 4o "overkill" compared to 4o mini?
Does 4o always outperform o3 mini or o1, or are there cases where the smaller models do just as well?
Should people be prompting reasoning models differently than 4o?
As a consumer-facing product, none of this feels intuitive. Is anyone else finding this whole model lineup needlessly complicated?
