QUERY FAN-OUT TECHNIQUE IN AI MODE: NEW DETAILS FROM GOOGLE

Summary from the TLDR AI newsletter

Google's query fan-out technique, available in AI Mode, Deep Search, and some AI Overview experiences, makes multiple background searches based on an initial question. It uses a large language model to interpret queries and 'fan out' to multiple related searches, including on topics the user never explicitly mentioned. The responses are then combined into a single response with links.
