How can you get the model to give you the categories to begin with?

How can you get the model to give you the categories to begin with?

I'd recommend using sentence-transformers for this. There are some tutorials online (like this one), which can also be useful here. Although, if you're interested in running with transformers.js, you should be able to reimplement some of the helper functions in JS, perhaps those needed as preprocessing or postprocessing steps on top of the model itself (which you can run with transformers.js).

Nowadays, you'd probably be able to do this with more powerful and up-to-date LLMs... but I've had success with the above-mentioned approach in the past.
