We wanted to share a quick update on one notable change we are making to the new Bing based on feedback from you all.
As we mentioned recently, very long chat sessions can confuse the underlying chat model in the new Bing. To address these issues, we have implemented some changes to help focus the chat sessions.
Starting today, the chat experience will be capped at 50 chat turns per day and 5 chat turns per session. A turn is a conversation exchange which contains both a user question and a reply from Bing.
Our data has shown that the vast majority of people find the answers they’re looking for within 5 turns and that only ~1% of chat conversations have 50+ messages. After a chat session hits 5 turns, people will be prompted to start a new topic. At the end of each chat session, context needs to be cleared so the model won’t get confused. Just click on the broom icon to the left of the search box for a fresh start. As we continue to get feedback, we will explore expanding the caps on chat sessions.
Thank you for all your feedback to date and please continue to send us your thoughts on the changes we are making to the product.
