I love the pencil-sketch style of your finding. Really cool.
I am using OpenAI GPT3 with a single (but long) prompt, explaining how to come up with the names that I think would be interesting.
Honestly, people who just about "prompt engineering" are pretty on point. It requires a bit of experimentation, but in this case I didn't have to do any fine tuning of the model itself, just the prompt.
I might come up with an array of different prompts to alter results, depends on user preferences.
