Our team compiled data from independent sources and our own interal research study to prepare this report sharing a variety of generative AI statistics, including market share, use case trends, and commercial usage by industry. Since different sources used different methodologies for some of their calculations, our model leveraged a weighted average of all sources, weighted based on each source’s age, credibility, and generally reported accuracy. Additionally, we applied this weighted model to the last 12 months to create a picture of last year’s generative engine optimization statistics and utilization trends.
