The current balance of power in open models

Open-weight models, such as Meta’s Llama and Alibaba’s Qwen, provide public access to model weights, while true open-source models additionally release training data and code. Chinese companies currently lead in open-weight model downloads and performance benchmarks, with models like GLM-5.3 and Kimi K3 significantly outperforming top American counterparts on the Artificial Analysis Intelligence Index.
