How websites like this one can generate names based on prompts?

Question

I just found this site that provides AI-powered name generators for some of their generators. They can generate names based on prompts that can either keywords or descriptions (that provide more control over the outputs). While I couldn't find any information about how this site works, do they use LLMs or specialized models for this task?

Answer 1

Though the technical implementation of NameGen.com isn’t publicly disclosed, they disclosed below relevant section on your link.

For example, Diminutives, our nickname tool, creates dozens or even hundreds of nicknames based on the letters and sounds of your full name. Meanwhile, the Generative Names tool uses an algorithm to create thousands of non-existent names, perfect for that fantasy novel or sci-fi screenplay you’re writing.

We usually don't call the application chain involving LLM a simple algorithm, and LLM currently isn't targeted for use cases to generate hundred or thousands of names in one go. Also they have "Best Picked by AI" selection out of a bunch of already generated names. All these clues hint their implementation might be some proprietary fast statistical ML algorithm, not large pretrained foundation transformers. And they have additional applications of AI/LLMs for some advanced functionalities.
