Different AI search tools may return different answers for the same or similar searches. This difference in results is expected. It occurs because each large language model (LLM) uses a different approach to find results and
generate answers that match your search.

## Overview of how LLMs create responses {#aisearch-differences__section_zcr_zfz_ygc}

Large Language Models don't retrieve answers from a single source. Instead, they generate responses by predicting the next most likely word, one at a time, based on patterns they've learned from the data they were trained on.  
Because of that, several factors can make the answers vary each time. The factors include:

* Probability
* Multiple good answers
* Context sensitivity
* LLM variation
{#aisearch-differences__ul_pxw_4pg_zgc}

Answer generation involves probability, context, and variation. Therefore, responses to the same question can differ slightly each time it is asked, and from provider to provider.
