Meituan Launches LongCat-2.0: A Trillion-Parameter Model Trained on 50,000-Card Domestic Computing Clusters
Meituan's technology team has officially announced the release of LongCat-2.0, a groundbreaking trillion-parameter large language model. This release marks a significant milestone as the industry's first model of this scale—boasting 1.6 trillion total parameters—to complete its entire training and inference lifecycle on a domestic computing cluster featuring 50,000 cards. LongCat-2.0 was pre-trained from scratch and features native support for an ultra-long context window of 1 million tokens. Specifically engineered for "Agentic Coding" tasks, the model is designed to enhance efficiency and stability in code understanding, generation, and execution. With an average activation of approximately 48B parameters and a dynamic range of 33B to 56B, LongCat-2.0 represents a major leap in domestic AI infrastructure and specialized software engineering capabilities.
