No idea, but these options come to my mind:
- A way to tell us that some day it will be changed to something else, maybe Gemini 3.6 Flash (RIP old Gemini 3 Flash)
- There will be various “priority” levels with different costs. Think of it as something similar to the modes expressed in https://ai.google.dev/gemini-api/docs/pricing (Standard, Batch, Flex, Priority).
I’m more inclined it is option 2.
