Short, succinct and no AI in sight.

"Abstract The Paxos algorithm, when presented in plain English, is very simple."

include a SUMMARIUM in Latin and ΣΥΝΟΨΙΣ in Greek, for that real Scholar effect.

Some titles stick. "Attention is all you need". "SSA is functional programming". Plus more people see the title than read the abstract. Only one I got to name myself was "Shared Memory Remote Procedure Calls" which I now realise is in exactly the same theme of given the title, you don't need the abstract or the contents.

IMO the most memorable papers contain some unexpected simplification: a complicated problem turns out to reduce to something much simpler [0], perhaps for a counterintuitive reason [1].

So a memorable abstract should advertise that the paper contains some cute little trick. This may not help you actually publish though
