No idea. First, any fine tuning rules out botpress and voiceflow - botpress is hardcoded to some models, voieceflow too , none supports custom models. Second, that would require significant preparation - do you even HAVE enough data? It owuld require an investigration what you MEAN by "typically respond" - maybe it is possible, using a 16k GPT 3.5 model, to get away with a good database and a large prompt defining the style of answer you give. I have worked with that in the past - it works, until it does not anymore, then it is down to prepare a LOT of data (thousands of conversations) for the AI to naturally get the style and STILL use likely embeddings to handle the knowledge part. The first is a 4 digit budget, the later can easily reach 5 digits - the training being the smaller problem, data preparation and validation being the main one. Note that Bottpress itself is self-limiting here- the way they use knowledge base does not allow for anything more complex, I think they are hardcoded AT THE MOMENT to the small gpt3.5 model, that gives them VERY little headroom for complex prompts. Just as note - that one has 4000 tokens, I work on full Ai agents bsides, and here 4000 token is the input limit for the personality and profdession section.
