… end quote. In the first week post-release, Homes.ai is having a huge impact on user engagement. Site visitors that hit the AI mode are on the site for 16 minutes, 50 seconds, as opposed to four minutes, 24 seconds for non-users. AI users do nearly four times as many searches, favorite seven times as many properties, look at four times as many properties, and submit seven times as many email leads. This transformative home search experience is powered by Microsoft Azure OpenAI Advanced AI Models, integrated with several other large and small models, including some models from AWS, as well as our own proprietary AI model. Using multiple models gives us tremendous flexibility and keeps token costs down. Using dynamic example injection, queries that originally consumed 2,000 tokens have been optimized to just 20 tokens. Unlike other AI implementations, Homes AI data remains entirely within the homes.com proprietary ecosystem and is never used to train or refine external AI models, giving us a real advantage as we build out the best-in-class real estate AI. While we're launching the capability of Homes.com, we plan to deploy it to Apartments.com, CoStar, LoopNet, Land, Biz by …

If you normalize these portals' financials from their home countries to the U.S. on a GDP basis, they would be generating $4 to $21 billion in revenue in the U.S. and $1.5 to $11 billion of EBITDA in the U.S., which is orders of magnitude more than anyone has ever generated in the United States. We believe we can generate $4.75 billion of revenue and $2.85 billion of EBITDA with Homes.com inside the next 13 years. Apartments.com has a very similar business model to Homes.com, and grew revenue initially at a measured pace, but now over 13 years has reached $1.2 billion of revenue run …
