Meituan Launches LongCat-2.0: A Trillion-Parameter Model Trained on a 50,000-Card Domestic Computing Cluster
Meituan's technology team has officially unveiled LongCat-2.0, a groundbreaking trillion-parameter model that marks a significant milestone in AI development. As the industry's first model of this scale to complete its entire training and inference lifecycle on a domestic computing cluster of 50,000 cards, LongCat-2.0 features 1.6 trillion total parameters with a dynamic activation range. Pre-trained from scratch, the model natively supports a 1M long context window. Its architecture is specifically engineered to excel in Agentic Coding tasks, focusing on the efficient and stable understanding, generation, and execution of code. This release highlights the growing capability of domestic infrastructure to support massive-scale AI workloads and specialized coding applications.
