Summary

The "State of Open Source on Hugging Face: Spring 2026" report highlights a rapidly expanding open-source AI ecosystem, with users, models, and datasets nearly doubling in 2025 to 11 million users, over 2 million models, and 500,000 datasets, reflecting a shift towards active participation and derivative artifact creation. Geographically, China has surpassed the U.S. in monthly and overall model downloads, with Chinese organizations significantly increasing their open-source contributions, while independent developers now account for 39% of all downloads. There's a strong trend towards smaller, more accessible models, which are downloaded and deployed at higher rates due to practical constraints, alongside a mean model size increase driven by quantization and Mixture-of-Experts architectures. Open source AI is increasingly linked to national sovereignty initiatives, with countries like South Korea and Switzerland investing in domestic models and infrastructure. Specialized sub-communities such as robotics and AI for science are experiencing explosive growth, with robotics datasets becoming the largest category on the Hub, underscoring open source as a foundational layer for AI development, adaptation, and deployment.

Key takeaway

The open-source AI ecosystem on Hugging Face doubled in users and models in 2025, with China emerging as the dominant force, surpassing the U.S. in model downloads (41% share) and repository growth, exemplified by DeepSeek-R1 and Alibaba's Qwen (113K+ derivatives). Smaller models (1-9B parameters) now drive adoption due to practical deployment benefits, while robotics datasets exploded 23x, underscoring open source's critical role in democratizing AI, reducing compute costs, and enabling national sovereignty.
