PanGu-Σ vs. ERNIE 5.1

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.

ERNIE 5.1 is Baidu’s advanced large language model platform designed to deliver high-level reasoning, autonomous agent behavior, creative intelligence, and enterprise-scale AI performance while dramatically improving parameter efficiency and training cost optimization. Developed as the next evolution of the ERNIE model family, ERNIE 5.1 inherits the foundational capabilities of ERNIE 5.0 while reducing total parameters and active parameters to create a more efficient and scalable AI system capable of flagship-level intelligence. The model performs strongly across global AI leaderboards and benchmark evaluations for reasoning, world knowledge, mathematical problem solving, search capabilities, and agentic workflows, placing it among the top-performing AI systems internationally. ERNIE 5.1 introduces a disaggregated fully asynchronous reinforcement learning infrastructure that separates training, inference, reward systems, and agent loops to improve scalability, stability, resource utilization, and long-horizon task optimization. The platform also includes FP8 low-precision optimization, elastic resource scheduling, and reinforcement learning consistency improvements that reduce latency and improve overall model efficiency. Baidu developed a multi-stage reinforcement learning training pipeline centered on expert model specialization and on-policy distillation, enabling ERNIE 5.1 to combine capabilities in reasoning, coding, conversational AI, creative writing, and agentic tasks without performance degradation between domains. ERNIE 5.1 demonstrates advanced creative generation capabilities with strong contextual awareness, emotional understanding, narrative pacing, and stylistic adaptability that support storytelling, professional writing, and AI-assisted creative production.
