Luckin Coffee Launches AI Assistant Powered by Doubao Model
Luckin Coffee has taken a significant leap into AI-powered customer service with the launch of its new AI assistant on May 26. Available through its official app and WeChat mini-program, this innovation marks version 1.0 of what the company describes as an "intelligent coffee butler."
The assistant, developed in partnership with Volcano Engine, harnesses the power of the Doubao large language model. It employs advanced intent recognition and slot extraction technologies to interpret customer preferences with remarkable accuracy. Users can now place orders through simple voice commands or text inputs, while the system automatically processes specifications like temperature and taste preferences.

Behind the scenes, Luckin has optimized the assistant for lightning-fast performance. Through prompt engineering, responses occur in milliseconds - crucial for maintaining smooth operations during peak hours. The company has built extensive real-world ordering datasets to handle complex requests efficiently.
Security hasn't been overlooked. A dedicated large language model firewall protects against dozens of potential attacks, safeguarding sensitive user data. Performance testing ensures stability even during high-traffic events like new product launches.
Perhaps most intriguing is the assistant's learning capability. It continuously refines its recommendations based on user interactions, promising increasingly personalized service over time. Could this be the future of quick-service retail?
