NanoGPT now offers access to Step-2-16k, making us one of the few services providing easy access to this powerful model. Created by Chinese AGI startup StepFun, Step-2-16k has emerged as China's top-performing LLM and ranks an impressive 5th globally on LiveBench, trailing only behind models from OpenAI and Anthropic.

Summary

• Powerful Performance: Ranks 5th globally on LiveBench, leading all Chinese LLMs
• Advanced Architecture: Built on trillion-parameter MoE architecture with 16k context window
• Specialized Strengths: Exceptional at instruction following (86.57 score) and reasoning tasks
• Cost-Effective: Cheaper than the other top models, for enterprise-grade AI capabilities

Step-2-16k is the flagship model from StepFun, a Shanghai-based AGI startup that has quietly emerged as one of China's most formidable players in the LLM space. Unlike competitors who focus heavily on marketing, StepFun has taken a research-first approach, resulting in a model that delivers exceptional real-world performance.

The model's name reflects its 16,000 token context window which is long enough for most queries. Built using a Mixture of Experts (MoE) architecture with over a trillion parameters, Step-2-16k represents a significant advancement in efficient, large-scale language models.

According to LiveBench, an LLM evaluation benchmark co-founded by Turing Award laureate Yann LeCun, Step-2-16k demonstrates remarkable capabilities across various metrics. It particularly excels in instruction following with a score of 86.57, meaning it's able to understand and execute complex user requests with high accuracy.

Step-2-16k is difficult to access outside of China, so we're very excited to make it available to everyone through NanoGPT.
