Considering that it’s a language task, LLMs exist, and the cost, it’s a reasonable assumption. It’d be pretty silly to analyse a bag of words when you have tools you can use with minimal work with much better results. Even sillier to spend over $200 for something that can be run on a decade old machine in a few hours.
Did you see something that said it was an LLM?
Edit: Indeed it’s an LLM. They published the model here: https://huggingface.co/reglab-rrc/mistral-rrc
