The significant price movement follows the company's official open-source release of its trillion-parameter large language model, LongCat-2.0, on July 6th.

The LongCat-2.0 model boasts a total of 1.6 trillion parameters, with an average activation of approximately 48 billion. Its architecture incorporates LongCat sparse attention and N-gram Embedding, which enhances the efficiency of long-context processing and token-level representation capabilities. Furthermore, the integration of dynamic activation has significantly strengthened its performance in code comprehension, generation, and execution.

Separately, Moore Threads has announced the successful adaptation of this model to its AI training and inference integrated full-feature GPU computing card, the MTT S5000, along with its MUSA software stack.

This adaptation process covered the entire deployment pipeline, including model loading, inference engine startup, optimization of key operators, deployment verification, and accuracy validation. The completion of this work enables LongCat-2.0 to achieve stable and efficient inference performance on the MTT S5000 hardware platform.
