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 pioneering trillion-parameter model. This release marks a significant milestone as the industry's first model to complete its entire training and inference lifecycle on a domestic computing cluster consisting of 50,000 cards. LongCat-2.0 features a total of 1.6 trillion parameters with a dynamic activation range between 33B and 56B, averaging 48B. Built from scratch, the model natively supports an ultra-long context window of 1 million tokens. Its architecture is specifically designed to optimize Agentic Coding tasks, aiming to provide high efficiency and stability in code understanding, generation, and execution. This development highlights a major step forward for domestic hardware capabilities in supporting massive-scale artificial intelligence models.
