All I saw were attempts to reproduce some chatgpt output.
If you want to add a new class, to update an existing one, it requires training a new model. Sometimes this is ok and sometimes it's not. This is why we generally prefer a hybrid approach where some classes are using traditional models (BERT based) while others are determined by the LLM.
What I'd like to see more of is systematic comparison between chatgpt and classic models. I was hoping to see a bit of this in this article and was disappointed.
We're working on putting together a better comparison specifically along the lines of accuracy between the LLMs (chatgpt, bard, falcon) and also traditional models. Hope that one hits the spot for you! Are their specific metrics you think might be interesting? We were primarily looking at f1/accuracy for this task, but also attempting to see what types of classes they work well in using semantic similarity.
