NVIDIA CEO Jensen Huang, in his latest interview with foreign media, publicly endorsed Chinese open-source AI large models in a rare move. He said bluntly: these Chinese large models are excellent, and excellent open-source large models should be used — excellent open-source AI large models greatly benefit the entire industry. This is the first time the head of NVIDIA has, in the context of US-China AI competition, backed Chinese open-source models at such a high profile. Multiple foreign media follow-up reads: behind Huang's words is the fact that Chinese vendors — represented by DeepSeek, Qwen, Kimi, Zhipu, ByteDance Doubao — concentrated in 2025–2026 in shipping 2T-parameter MoE flagships, long-context and multimodal versions, and consistently occupied the top of the Hugging Face open-source leaderboards. Open source means global developers can reproduce, distill, and deploy at low cost; Chinese vendors used this to push the performance/cost curve down as a whole, directly breaking the old narrative that Chinese AI is two-to-three generations behind the US. From a technical angle, Chinese open-source models have already formed three main lines: first, MoE architectures that push cost down to the extreme — Qwen3 and DeepSeek V3 have walked the 2T-total / 100B-active sparse-activation path; second, deep fusion of long context and multimodality — Kimi, Zhipu GLM etc. have made million-token context + visual understanding a default capability; third, inference-side engineering optimization — focusing on KV cache, quantization, and speculative decoding, pushing the open-source flagship API price down to a fraction of the closed-source flagship. Huang's statement is essentially an admission of one fact: open-source model iteration speed has caught up to, and in some niches surpassed, closed source, and GPU vendors need to support both ecosystems at the hardware level, while pitting open-source and closed-source as opposing narratives no longer fits the industry's interest. The next thing to watch isn't who wins or loses, but whether Chinese open-source models can continue to deliver breakthroughs in multimodal world models and AI Agent infrastructure — that's NVIDIA's most-watched next growth curve.
