Yelp shares rose 2% Thursday after the company integrated OpenAI's GPT-Live-1 into Yelp Host, its voice AI solution for restaurants, and Hatch, its AI communication platform for service businesses. The tools are among the first solutions to deploy the model, whose full-duplex voice architecture supports natural pauses, interruptions and overlapping speech. GPT-Live-1 acts as the front-end voice layer, detecting caller tone and responding in nearly any language. Yelp Host has handled more than 1 million restaurant calls since launching in October 2025, while Hatch manages tens of millions of leads across voice, text, email and web, representing billions of dollars in customer-attributed value annually. Yelp said initial production testing improved call handling and reduced transfers.
