Which, from a naming standpoint, doesn't make any sense

It’s still bad versioning and will confuse people.

But it still starts with “Gemini”. It would be better if they called it Gemini Omni 4, 4.1 etc. Otherwise call it just Omni 1.2 and drop the Gemini prefix.

But it's not version 4 of Gemini Omni. It's version 1.2 of Gemini Omni. 4 is for normal Gemini.
