Large Language Models, Open Source, and the State of the Art

China’s AI models have undergone a remarkable evolution over the past two years. What was still considered a „catch-up game“ against Western models in 2023 has turned, by 2025/2026, into a field where Chinese models compete on equal footing in many areas — or, measured by price-performance ratio, are even ahead. This section analyzes the models, their capabilities, and the technological trends behind them.

Five Technological Trends Shaping China’s AI Models

1. Efficiency as a Design Principle

Perhaps the most significant contribution of Chinese AI research lies not in raw performance but in efficiency. DeepSeek’s R1 demonstrated that state-of-the-art results are possible with significantly fewer computing resources. This approach is no accident — it’s a response to US export restrictions that limit access to Nvidia’s high-end GPUs.#

The result: Chinese labs have developed training techniques that optimize resources — from Mixture-of-Experts architectures to innovative reinforcement learning methods. What began as necessity is now a competitive advantage: Chinese models often cost a fraction of their Western alternatives to use.

2. Open Weight as Ecosystem Strategy

hinese companies dominate the open-source model landscape. Alibaba’s Qwen family has more cumulative downloads on Hugging Face than Meta’s Llama. According to an MIT study, Chinese open-source models now surpass US models in total download volume.

The reasons are multifaceted. Open-weight models accelerate adoption, build developer communities, and set de facto standards. For companies like Alibaba, the open model family serves as an entry point into the commercial ecosystem — developers who use Qwen eventually end up on Alibaba Cloud.

For the global developer community, this means: access to near-frontier AI has never been broader or more affordable.

3. Multimodality and Video Generation

Chinese labs are among the leading players in multimodal AI. ByteDance’s Seedance 2.0 produces the viral AI videos currently dominating social media. Moonshot’s Kimi K2.5 combines text, image, and video in a single model. Alibaba’s Qwen3-Max-Thinking reportedly processes all modalities.

The focus on video is no coincidence: China’s internet is more video-centric than its Western counterpart (Douyin/TikTok, Bilibili, Kuaishou). AI-generated video content meets a massive, receptive audience.

4. Reasoning and Agentic AI

ith DeepSeek’s R1, China achieved one of the first globally recognized breakthroughs in „reasoning“ — models that think through complex problems step by step. All major labs are now working on reasoning capabilities.

The next step: agentic AI. Models that don’t just answer but autonomously execute tasks. This trend is particularly advanced in China because the super-app culture (WeChat, Alipay) provides a natural environment for AI agents. Alibaba’s Qwen can already process purchases, order food, and book travel — all within a single conversation.

5. Multilingualism and Cultural Adaptation

Chinese models are increasingly optimized for multilingual applications. Given China’s linguistic diversity (Mandarin, Cantonese, dozens of dialects and minority languages), Chinese labs have experience with linguistic complexity. This competence is now being transferred to international markets.

At the same time, this is an area that warrants critical observation: Chinese models are subject to content requirements under Chinese regulation. How this affects their use in non-Chinese contexts is one of the central questions we regularly examine in this section.
