What I’ve learned about writing AI apps so far

By Chris Coyier on

Some plain-language baby-bear porridge writing from Laurie Voss: Is what you’re doing taking a large amount of text and asking the LLM to convert it into a smaller amount of text? Then it’s probably going to be great at it. If you’re asking it to convert into a roughly equal amount of text it will […]

API Testing Clients

By Chris Coyier on

I was just working on a POST API at work. You POST some data to a URL endpoint, you expect a response. Buckle up, that’s the job sometimes. Happy path responses, error responses, handling incomplete or bad data, etc. You can just rawdog a web browser for this kind of work, building some kind of […]
