What is Hunyuan-Large
Hunyuan-Large is a large Mixture-of-Experts (MoE) model launched by Tencent, with 389 billion total parameters and 52 billion activated parameters, making it the largest open-source MoE model by parameter scale in the industry. Based on the Transformer architecture, it supports text sequence inputs of up to 256K, significantly enhancing the processing capability for long-text tasks. Hunyuan-Large performs excellently across 9 major capability dimensions, including long-context processing, Chinese and English natural language processing, code generation, and mathematical operations, surpassing mainstream open-source models such as Llama3 and Mixtral. Hunyuan-Large is trained with high-quality synthetic data, and through synthetic data augmentation training, it can learn richer representations and better generalize to unseen data. The model adopts Grouped Query Attention (GQA) and Cross-Layer Attention (CLA) strategies, reducing the memory footprint and computational overhead of the KV cache and improving inference throughput.
