Yep, it's surreal.

Love this reference :)

In my current experience:

- o3 is the bestest and my go-to, but its strength comes from it combining reasoning with search - it's the one model you can count on finding things out for you instead of going off vibe and training data;

- GPT 4.5 feels the smartest, but also has tight usage limits and doesn't do search like o3 does; I use it when I need something creative done, or switch to it mid-conversation to have it reason off an already primed context;

- o4-mini / o4-mini-hard - data transformation, coding stuff that doesn't require looking things up - especially when o3 looked stuff up already, and now I just need ChatGPT to apply it into code/diagrams;

- gpt-4o - only for image generation, and begrudgingly when I run out of quota on GPT 4.5

o3 has been my default starting model for months now; most of my queries generally benefit from having a model that does autonomous reasoning+search. Agentic coding stuff, that I push to Claude Code now.

I’d also recommend basically always having search enabled. That’s eliminated major hallucinations for me.

lol yep, fully get that. And I mean I'm sure o4 will be great but the '-mini' variant is weaker. Some of it will come down to taste and what kind of thing you're working on too but personal preferences aside, from the heavy LLM users I talk to o3 and gemini 2.5 pro at the moment seem to be top if you're dialoging with them directly (vs using through an agent system).
