中国开源大模型2025年夏季超越美国，生态优势持续扩大。
The ATOM Report: Measuring the Open Language Model Ecosystem
- 基于下载量、衍生模型和推理市场份额等多维度评估
- 2025年夏季起中国模型超越美国模型并持续拉大差距
- 适合关注AI生态格局变化的研究者与政策制定者
本文对领先的开源语言模型生态系统进行了全面的采用情况分析，聚焦于约1500个主流开源模型，包括阿里巴巴的通义千问（Qwen）、深度求索（DeepSeek）及元公司的Llama等，这些模型是研究人员、创业者和政策制定者的重要基础。通过综合分析Hugging Face下载量、模型衍生数量、推理市场占有率及性能指标，揭示出一个明确趋势：自2025年夏季起，中国模型在整体生态中超越其美国同行，并进一步扩大领先优势。
原文摘要 · Abstract (English)
We present a comprehensive adoption snapshot of the leading open language models and who is building them, focusing on the ~1.5K mainline open models from the likes of Alibaba's Qwen, DeepSeek, Meta's Llama, that are the foundation of an ecosystem crucial to researchers, entrepreneurs, and policy advisors. We document a clear trend where Chinese models overtook their counterparts built in the U.S. in the summer of 2025 and subsequently widened the gap over their western counterparts. We study a mix of Hugging Face downloads and model derivatives, inference market share, performance metrics and more to make a comprehensive picture of the ecosystem.
