Open Model Landscape in Summer 2026 Shows Rapid Growth and Shifting Development Strategies
Key points
- Hugging Face models grew to 2.96 million, datasets to 1 million in 2026.
- Chinese labs released larger open models than American labs in most of 2026.
- Hardware vendors AMD and NVIDIA are top contributors of new open models.
- Quantization allows large models to be runnable quickly by the community.
Rapid Expansion of Open Models and Datasets
The Hugging Face platform experienced substantial growth in its open model and dataset repositories during 2026. The number of public model repositories increased from 2.43 million to 2.96 million, while datasets expanded from 711,000 to 1 million. Spaces also grew from 1.00 million to 1.44 million, indicating a general expansion of the open-source AI ecosystem.
Dominance of Large Models from Chinese Labs
In 2026, Chinese laboratories frequently released larger and more performant open models compared to their American counterparts. The largest open models from Chinese labs ranged from 754 billion to 2.78 trillion parameters monthly, while American labs generally stayed under 130 billion parameters, with exceptions like NVIDIA's Nemotron 3 Ultra at 561 billion parameters. This shift indicates a change in development strategy, with some Chinese labs skipping the traditional progression from smaller to larger models.
Strategic Approaches to Model Size
Some Chinese labs, such as Moonshot, MiniMax, Xiaomi, and Z.ai, primarily publish models larger than 70 billion parameters, making them difficult for individual developers to run locally. In contrast, companies like Tencent and Alibaba Qwen offer a full spectrum of model sizes, from under 1 billion parameters upwards. The ability of the community to quickly quantize large models has made it less necessary for labs to release smaller versions to ensure accessibility, turning model size into a statement of intent rather than a limitation of capability.
Hardware Vendors Drive Open Model Contributions
Hardware manufacturers AMD and NVIDIA emerged as the leading contributors of new open models in 2026, each releasing over 200 new model repositories. This strategy reflects a realization that providing open models optimized for their hardware can serve as a method to increase chip sales. LiquidAI ranked third in contributions with approximately 100 new repositories.
