Sharing AI chatbot accounts can degrade performance as the AI is trained on diverse and potentially conflicting data from multiple users. This can lead to confused outputs and a less effective user experience, according to users who have experienced this issue.
“So, a lot of the people I interviewed are about 21, 22, you know, college students on a budget, don't really want to pay for premium chatbots themselves. So, a lot of them decided to share the wealth with their friends who are also studying with them.”
“So, not everyone is studying the same thing at college. So, one person I spoke with, she's a nursing student and her roommate does education studies. And so, when the nursing student was trying to come up with some exam style questions to practice with the chatbot, it would kind of draw on information from her roommate's studies.”
“And then as the chatbot is trained on all the different data over time, it kind of learns from that and starts just kind of getting confused. You know, your brain can only process so many things at one time, the same goes for like an algorithm. So it just kind of all gets mixed up and creates some really bizarre outputs.”
