CoStar’s Apartments.com expanded its integration with OpenAI’s ChatGPT alongside the launch of GPT-6 Astra, enabling in-chat rental search and leasing actions.
Users can access live unit availability, pricing, fees, rich media, messaging, tour requests, and bookings without leaving ChatGPT.
Apartments.com reported nearly 40% growth in referral traffic from ChatGPT since the app launched in early August.
OpenAI featured Apartments.com in a GPT-6 Astra apartment-hunting demo, positioning the integration as a driver of higher-intent leads for advertisers.
