Ask HN: "My GPT"s

Have you created "My GPT" instances (https://openai.com/blog/introducing-gpts)?

Please show them! And tell us how you customized them (for example showing the instructions under "Edit GPT").

I have just started to dabble in it, with mixed results.

But I find it really remarkable. First, the split screen with "talking to the GPT model and customizing it" on the left and "previewing how it would answer questions" on the right just feels like programming with words. Like the right side is a debugger with variable watch window.

Second, ChatGPT has started giving me two answers side by side and asking me which one I prefer.
