What is PanGu-α?

PanGu-α is developed with the MindSpore framework and is powered by an impressive configuration of 2048 Ascend 910 AI processors during its training phase. This training leverages a sophisticated parallelism approach through MindSpore Auto-parallel, utilizing five distinct dimensions of parallelism: data parallelism, operation-level model parallelism, pipeline model parallelism, optimizer model parallelism, and rematerialization, to efficiently allocate tasks among the 2048 processors. To enhance the model's generalization capabilities, we compiled an extensive dataset of 1.1TB of high-quality Chinese language information from various domains for pretraining purposes. We rigorously test PanGu-α's generation capabilities across a variety of scenarios, including text summarization, question answering, and dialogue generation. Moreover, we analyze the impact of different model scales on few-shot performance across a broad spectrum of Chinese NLP tasks. Our experimental findings underscore the remarkable performance of PanGu-α, illustrating its proficiency in managing a wide range of tasks, even in few-shot or zero-shot situations, thereby demonstrating its versatility and durability. This thorough assessment not only highlights the strengths of PanGu-α but also emphasizes its promising applications in practical settings. Ultimately, the results suggest that PanGu-α could significantly advance the field of natural language processing.

What is PanGu-Σ?

Recent advancements in natural language processing, understanding, and generation have largely stemmed from the evolution of large language models. This study introduces a system that utilizes Ascend 910 AI processors alongside the MindSpore framework to train a language model that surpasses one trillion parameters, achieving a total of 1.085 trillion, designated as PanGu-{\Sigma}. This model builds upon the foundation laid by PanGu-{\alpha} by transforming the traditional dense Transformer architecture into a sparse configuration via a technique called Random Routed Experts (RRE). By leveraging an extensive dataset comprising 329 billion tokens, the model was successfully trained with a method known as Expert Computation and Storage Separation (ECSS), which led to an impressive 6.3-fold increase in training throughput through the application of heterogeneous computing. Experimental results revealed that PanGu-{\Sigma} sets a new standard in zero-shot learning for various downstream tasks in Chinese NLP, highlighting its significant potential for progressing the field. This breakthrough not only represents a considerable enhancement in the capabilities of language models but also underscores the importance of creative training methodologies and structural innovations in shaping future developments. As such, this research paves the way for further exploration into improving language model efficiency and effectiveness.
