Overview
Public Gemini 4 versions
Confirmed
Not confirmed
Google has indicated that Gemini 4 is not yet a full multi-variant family in public release. In practical terms, that means there is no broadly available Gemini 4 Pro, Flash, or Nano equivalent you can use today; the public Gemini 4 offering is currently centered on Argon.
If by “released” you mean the first announcement/limited rollout, the date is September 30, 2026.
If you mean when most users and developers could actually start using it, the date is October 13, 2026.
