>Technical principles of T1
- Innovative architecture design: Hunyuan T1 follows the innovative architecture of Hunyuan Turbo S, adoptingHybrid-Mamba-Transformer fusion mode. It is the industry's first lossless application of a hybrid Mamba architecture to an ultra-large reasoning model. By optimizing the traditional Transformer structure, the architecture reduces computational complexity and KV-Cache memory usage, significantly lowering training and inference costs.
- Efficient long text processing capability: Hunyuan T1 shows unique advantages in the field of ultra-long text reasoning. The hybrid Mamba architecture is specially optimized for long-sequence processing and can effectively solve the common problems of context loss and long-distance information dependency in long-text reasoning. Under a similar number of activated parameters, decoding speed is increased to twice the original.
