We have 4o and o4 (and hilariously, a 4o-mini and an o4-mini), so maybe we should anticipate whatever creates the most naming chaos possible.

This must have been what the Microsoft investment was for: "use our product naming guidelines"

Please don't forget about o4-mini-high.

It may be GPT-4.55 as well. I find it really funny to explain someone non technical versioning of LLM models of different companies.

4.1 coming after 4.5 is plain mockery
