I think Haiku is fine (e.g.) for any task that you could almost, but not quite, complete with (regex?) find and replace.

You give it 3 examples of the change you want, then ask it to do the other 87. You'll end up saving time and “money”.

> Haiku is most definitely not fine for the code bases that I work on. Sonnet is probably fine for most daily tasks, but Opus is still needed to find that pesky bug you've been chasing, or to thoroughly review your PR.

Yeah, I hear that a lot, but it never comes with proof. Everyone is special.

I’m sure you’d find that Haiku is pretty functional if there were a constraint on your use.
