"128MB default with up to 3008MB max. You can submit a support ticket to get 10GB RAM, but I was too lazy to argue with AWS support."

Was this written before wide availability of 10g memory lambdas?

Surprisingly, 3GB is a real practical RAM limit for aws lambdas in 2025: you can only have more than that if you submit a support ticket. But it's not really mentioned anywhere in the docs.

The default Lambda quota for all accounts is 10240 MB. I've never seen it below that (in recent memory, at least), even on fresh accounts not connected to a big org.

I know I routinely use 10gb of RAM for my account that's never talked to support for the related CPU allocation.

Is what you're talking about a new thing? Or respectfully, are you just wrong?

They probably have never requested service limit increase to unlock all of AWS.

If they had, they would know that it involves many weeks of arguing with support, of course

Justifications upon justifications, man, so glad I no longer run infra.
