Why can't I turn off antigravity fast mode?

Google Antigravity

When I execute the /fast command in the Antigravity CLI, I get the following message:

/fast

⎿ Enabled fast mode.

Executing it again gives the following message:

/fast

⎿ Already in fast mode.

Can’t it be turned off? Or is it disabled by default when I enter Agy?

Was looking for this myself and came across this post. Type /planning to switch from /fast mode.
