Atuin AI sounds like a useful addition. The page suggests they're probably using hosted models:

  We use the latest frontier models, which already do a good job of generating commands using well-known binaries and CLIs. On top of that, we integrate a dataset powered by man pages and command outputs to ensure you get the correct command first.

This is great, but does it mean we'll need to log in somehow? It doesn't seem reasonable to expect the project maintainers to pay for the tokens.

EDIT: I was unaware of Atuin's 'hub' which does things like sync your shell history across computers. I think they use the same sign-in as they already use for that: https://hub.atuin.sh/register
