It's a little amusing to me that we ended up in a loop of (i) write bullet points, (ii) ask AI to expand bullet points into a long text, (iii) reader gets long text, (iv) reader uses AI to condense the long text into bullet points

I’d say it moves “all the complexity” to the backend if it were defining one REST endpoint for each page the client loads. With GraphQL, each resolver is individually much simpler logic, and there’s no effort to do the stitching.

So basically frontend+backend effort with GraphQL is much smaller than frontend+backend with REST

Ask HN: How are you testing your LLM prompts?

luccasiau — Sun, 02 Apr 2023 19:14:42 +0000

How do you make sure changing your prompts will work well? How do you ensure it doesn't break anything that is already working?

Changing prompts in small ways can lead to loads of unpredictable behaviors. And that's even more concerning as we build larger apps on something like LangChain, that requires the output to be very rigid.

My instinct would be to run a unit test-suite for every prompt change. Is there some already-existing framework for those? Or otherwise, how are you testing your changes?

Blog post I wrote when I was excited about Succession. It turned out surprisingly reminiscent of Twitter's current situation.
