Your response and the person you responded to were discussing copilot vs chatgpt. Both may "hallucinate". Copilot is more useful (to the GP and to me) - it's domain specific and well integrated, despite occasionally producing pure crap.
I also pay for copilot and don't for chatGPT.
>ChatGPT craze has wore off for me, because of constant hallucinations when you ask for something slightly more esoterical. And I can't justify paying 20$ for GPT-4 to have more convincing hallucinations
Integration has nothing to do with hallucinations.
