  • What type of code should you generate with AI?
    hn-ai· 27-abr

    I (and many people) have been thinking a lot about "what are the best tasks to do using AI." My personal framework I've been using is, you should use AI to generate code when: 1. The code is easy to validate 2. It is not important that a human understands it I find that the best thing to AI generate is something on the level of a pure function (easy to validate + not necessarily important to understand implementation as long as you understand the interface). I've tried doing things like generating whole services or applications, but those often violate rule 1 - it's hard to validate an entire application behaves "correctly" when "correctly" isn't really well defined - i.e., are there memory leaks, is it secure, is it able to be monitored, etc. I'm curious of others thoughts on this topic.…
