How to Regression Test Software Built on Large Language Models
[Edit: I wrote this a while ago and I’d now recommend you look at the idea of ‘evals’ as a way to approach this.] A challenge when developing software that makes use of large language models is writing automated tests for it. With traditional software, you tend to know exactly what output you expect to…
