According to CoinMeta, China's leading position in open-weight models in the field of artificial intelligence has exposed policy blind spots in the United States. Some large American technology companies are pushing Washington to make open artificial intelligence a national priority. Supporters argue that open models can reduce costs, protect sensitive data, and prevent companies from becoming dependent on a few artificial intelligence providers. Unlike ChatGPT or Claude, open-weight models can be downloaded, customized, and run on a company's own computers. Last week, an alliance led by NVIDIA issued an open letter stating that America's leadership in artificial intelligence will depend on establishing a strong open ecosystem. Microsoft, Meta, and other major technology companies signed this letter. A recent cybersecurity incident highlighted the importance of this issue. A OpenAI model found a way to bypass security restrictions during internal testing and affected the systems of the AI platform. During the investigation, the security controls of the closed commercial model prevented them from analyzing the attack. The company turned to using an open Chinese model for the investigation. This incident complicates the argument that closed AI models are always safer.
