Runtime for Startups now speaks of startup hours
The machine time is 10,000 startup hours, each an hour of a 2 vCPU, 4 GB sandbox. Storage kept free each month and the at-once limits are what Runtime for Startups includes; the amounts and terms are unchanged. GET /v1/usage now names its fields startupIncluded and startupLimits, with the same shapes. The old fields pot and potLimits still work for 30 days after this change ships, with a warning. See included usage.
Sign up with Google in one click, and start a sandbox from Home
"Start free, no card" opens Google sign-in at once, with no human check to wait for (a sign-in by email link still has one), and a new account's Home opens on a sandbox you start with one click, then the prompt to paste into your agent.
