Chinese AI Giant StepFun's Step-2-16k Model Crowned King of Chinese LLMs, Achieving Global Recognition
November 19, 2024 – In a landmark achievement for China's artificial intelligence sector, StepFun's latest language model, Step-2-16k, has emerged as the top-performing large language model (LLM) in China, according to the recent evaluations released by LiveBench. This cutting-edge model not only surpasses domestic competitors but also ranks fifth globally, closely trailing behind renowned international models like OpenAI's o1-mini-2024-09-12, GPT-4o-2024-08-06, and Gemini-1.5-pro-002.
What Happened
On November 19, LiveBench, a premier LLM evaluation benchmark co-founded by Turing Award laureate Yann LeCun, Meta's Chief AI Scientist, and institutions such as Abacus.AI and New York University, published its latest assessment results for large language models. The evaluation encompassed a comprehensive range of metrics, including mathematics, reasoning, programming, language understanding, instruction following, and data analysis.
StepFun's proprietary trillion-parameter language model, Step-2, particularly its Step-2-16k variant, achieved the highest technical performance among Chinese foundational models. This accomplishment places Step-2-16k as the only Chinese LLM to break into the top ten globally, securing the fifth position. Competing Chinese models from Tongyi Qianwen and DeepSeek also made notable entries on the leaderboard.
The Step-2-16k model is part of StepFun's Step series, which includes models like step-1-8k and step-1-32k, distinguished by their context lengths in tokens. The Step-2 series, featuring a Mixture of Experts (MoE) architecture with over a trillion parameters, is designed to enhance performance across various tasks such as text generation, logical reasoning, and mathematical problem-solving.
