For programming, sure. There are oodles of tasks that you can defer to AI for that aren't nearly as picky though.

For example, suppose you have a list of questions in a CSV, and you just want to categorize them by the "type" of question (e.g. technical, bureaucratic, procedural, a mixture, etc). You could have Fable do it, and it will work, but it probably won't work significantly better than Haiku, or even one of the cheaper Qwen or Deepseek models.

A lot of my AI usage does boil down to that. I use Opus for most of the actual tasks involving writing code, but for more mechanical and less complicated stuff I prefer the speed and the lower usage of my tokens and defer to Sonnet or Haiku.
