Meituan has unveiled LongCat-2.5, a 1.6 trillion parameter AI model trained entirely on Chinese-manufactured chips with limited memory per card. The model utilizes a novel distributed training architecture to manage its massive parameter count across numerous GPUs, employing techniques like parameter splitting and expert parallelism within supernodes. LongCat-2.5 also incorporates 4-bit precision for weights and activations, significantly boosting inference speed and reducing computational load, with reported performance competitive with models like Claude Opus 4.8 and 5.
