Deep Dive: Meituan’s Journey in Elevating AI Performance and Scalability


Realizing the integral role of AI in the modern internet market, Meituan built a robust AI team dedicated to infusing its operations with AI-driven solutions. From site selection to marketing, the company leveraged AI for better decision-making and customer experience. The primary tool of choice was TensorFlow, Google’s open-source deep learning framework. Known for its versatility and scalability, TensorFlow was employed for model training and distributed computing.


To address the burgeoning challenges, Meituan opted for re-architecting its infrastructure and optimizing its software. Partnering with Intel, Meituan integrated Intel® Xeon® Scalable processors into its TensorFlow system. These processors, known for their AI acceleration capabilities, became a crucial part of Meituan’s server clusters. Meituan underwent multiple stages of optimization, from boosting throughput for unit computing power to enhancing distributed computing. Techniques included employing Intel’s Advanced Vector Extensions and parallelization technology, optimizing load balancing, and enhancing communication mechanisms.


Through the combined optimizations, Meituan witnessed substantial improvements in system performance. They achieved near-linear acceleration for models with hundreds of billions of parameters, enabling a full year of sample data training in just one day. The TensorFlow-based Recommendation System also became more cost-effective and efficient. Furthermore, the optimizations made the system more user-friendly, leading to its adoption across multiple Meituan businesses, such as food delivery, ad platform, and community group buying.

Challenges and Barriers

Meituan’s rapid growth came with its own set of challenges. With the increasing scale and complexity of AI models, performance bottlenecks in TensorFlow became evident. Large-scale applications revealed issues with the official version of TensorFlow, such as memory resource wastage and scalability concerns. The rising total cost of ownership (TCO) also posed a significant challenge. Balancing the need for better performance with TCO considerations was a complex problem that Meituan had to address.

Future Outlook

Intel’s commitment to advancing AI technology, in tandem with partners like Meituan, paints a promising picture for the future. With a focus on delivering more accurate, personalized services to end-users, Intel aims to drive the AI industry’s development further, making the technology more accessible and cost-effective. As for Meituan, its mission remains steadfast: to help people lead better lives. With continuous investments in R&D and a commitment to digital transformation, Meituan is poised for even greater successes in the AI-driven digital age.
