Antigravity IDE - Gemini Flash 3.5 is "Fast" for a "Limited Time"?

I just installed Antigravity IDE on macOS. I am seeing the Gemini 3.5 Flash models labeled as “Fast” “Limited time”. Does anyone know what specifically this refers to?

Is it saying that the model is “fast” for a limited time, or that the model itself is only available for a limited time? Or something else?

Thanks for any insight!

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.
