Hi guys, I am trying to understand if it's possible to use Botpress to create a custom GPT. All I want is to train my own GPT on a specific knowledge base and let it answer questions when the user asks them. The flow makes everything very "robotic" and has less flow than platforms like Chatbase or CustomGPT.AI. I want to use Botpress though, thanks to it's strong API integrations. Any idea how to get what I want?
