Hi there and welcome to the Community, @NRV_Wayfinder 
Many thanks for sharing your point with us!
Yep, I see you’ve already discussed this question with my colleague Victoria. Her response and the comment by @Paul_D get to the heart of the issue.
The assistant’s performance is directly tied to its training (Instruction and Knowledge Base). As Paul’s example shows, a well-crafted instruction set can effectively prevent the model from giving irrelevant answers.
So, the current version of the AI assistant is already capable of the high accuracy, providing your files or knowledge base are comprehensive and free of inconsistencies. Here are some basic tips to make sure your instructions are well-structured and concise - Basic Tips For Your AI Chatbot Instruction
If you encounter any incorrect answers, please share the files you’ve uploaded along with the question asked, the wrong response you received, and the correct answer.
As you’ve already noted, errors can happen since it’s a bot. However, you can reduce them by refining your instructions, providing more detailed information, and correcting any mistakes as they arise
