I have tested it and I have got back “template” or “boilerplate” code. Not bad at all.
For example, i asked “simple Erlang nif in rust for elixir” and GPT4 gave me an answer that I need Rust, rustler, create a rustler module with mix, (simple) Rust code, an Elixir module and iex code to test. All with links and code, easily to be copied.
So overall not bad and much better than GPT-3.5.
Atm it is not a “danger” for developers: Architecture, special requirements etc. is still with us. But as a first code example within a minute (with ChatGPT plus) it is a good help. And easier than to go through several links in Github and blogs.
