In itself, the OpenAI-backed Bot has a lot of information. The goal of the GPT is to first specialize its knowledge.
In Natural Language you can tell it, “I want you to be an HTML expert”.
Now, the bot already knows that it is an HTML expert, the problem is that although it has the instruction, it surely does not know how to give that information, whether it is for novice, intermediate or expert users.
This is where we have to specify how to give that information, and we must be as detailed as possible. Now, you can give your own knowledge base in a PDF file that talks about the specific topic, but you must be very clear on how to provide that information, and at this point you should also tell him what he should not do, because if you ask him for a food recipe, even if he is an expert in HTML he will give you the food recipe, that is where you should tell him that he will not give more information unless it is HTML.
The learning of the bot is not by us, it is by OpenAI that specifies that in each interaction with the users it learns not on the basis of knowledge, but on the basis of natural language, because its knowledge base of training is taken from the Internet. So remember, your job is to specialize him in a particular topic by telling him what to do, telling him what not to do.
Now, you can tell him, you are an expert in HTML, and your knowledge base is the HTML.pdf file.
