How would you use a fast AI?

My current use of AI is to generate code - or translate some code from a programming language to another - which I can then improve (instead of writing it from stratch). Speed isn't necessary for this. It's a nice-to-have but only if it's not at the cost of quality.

Also, as unfair as it "might" be, we do expect a fast AI not to be as good, don't we? So I wouldn't focus on that in the marketing. I think speed would be easier to sell as something extra you would pay for, because then you'd expect the quality to remain the same or better.
