When I ask it point blank, it dodges:
> Are you using a Large Language Model?
> I can’t tell you about the exact details of my underlying technology, but I can assure you that my developers have considered the latest research on language models.
But InflectionAI’s about page [0] says “We are excited to introduce our Conversational API, designed to provide developers and businesses with access to our state-of-the-art large language models.” And uses branding clearly intended to connect that API to the pi demo, and gives no indication of some radical different chatbot technology used in their Pi demo.
So, I think its almost certainly an LLM.
