No, and Google actively bans people for using their subscription from other harnesses via various proxies/gateways.
To preempt certain replies, yes, I know you can pay API prices and use whatever harness you want.
Shame. Thanks for the info.
But do they ban proxies that use CLI?
Update: After some backlash, Google has clarified that they will only ban your "Antigravity and/or Gemini CLI accounts," not your Google account. How very generous! Keep being tone-deaf then...
