WeChat has opened its AI ecosystem to developers, with Didi as a first partner integrating its ride-hailing services into the WeChat AI Agent. Users can now book rides via natural language commands like "Call a Didi to the airport," enabling one-click car calling without switching apps. Initial services include regular, premium, and discounted cars, with more like Didi Hitch to follow. This collaboration demonstrates the feasibility of migrating complex services to AI Agents, signaling a shift toward native large-model interactions.
