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.
This is great!
I have been using Quickwit as a low cost search engine on Lambda. It works very well for my relatively small and infrequently updated dataset.
Unfortunately Quickwit devs have decided to not support the Lambda deployment mode going forward so eventually I'll need another option.
"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?

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