The long-running debate over how artificial intelligence (AI) should develop has now turned into a major fight in Silicon Valley. Tech companies are now publicly divided over whether powerful AI models should remain closed or open for everyone to use. The differences were mainly between the two groups. A set includes open artificial intelligence and Anthropic, while the other includes Microsoft, Nvidia, Meta, IBM, Palantir and a host of AI startups.
OpenAI and Anthropic believe that some advanced artificial intelligence models are too dangerous to be freely used. They argue that these powerful models should be tightly controlled because they can pose security risks. Microsoft, Nvidia, and many other technology companies believe that artificial intelligence should remain open source. They said open source AI could allow more people to improve the technology, build new businesses and check models for security flaws, The New York Times reported.
Why big tech companies are divided on artificial intelligence
Microsoft CEO Satya Nadella also supports open source AI, calling it “critical to a healthy AI ecosystem.” According to the New York Times, he signed an industry letter supporting open source artificial intelligence along with Jensen Huang and executives from Meta, IBM and Palantir.
Now, the divide extends beyond Silicon Valley, with both sides taking their arguments to Washington. Meanwhile, OpenAI and Anthropic have been quietly lobbying the U.S. government. The companies have warned Washington about Chinese open source projects, five people familiar with the matter said artificial intelligence model. Treasury Secretary Scott Bessant and President Donald Trump’s science and technology adviser Michael Kratsios have both been involved in discussions about protecting U.S. artificial intelligence technology.
How China is catching up in artificial intelligence
The main reason behind this battle is China’s rapid progress in the field of artificial intelligence. Chinese companies are quickly catching up with U.S. artificial intelligence companies through open source development. Two Chinese AI startups—Z.ai and Moonshot AI—recently released artificial intelligence models that are reportedly comparable to those from Anthropic and other U.S. companies. The releases have added to concerns within the U.S. artificial intelligence industry.

U.S. officials are currently examining possible actions against Chinese companies. However, the U.S. government has not yet decided to completely ban Chinese artificial intelligence models. Instead, officials are considering individual Chinese models as national security cases. Backers, including Microsoft and Nvidia, believe open source AI can speed innovation while allowing more researchers to discover security flaws.
Why OpenAI wants stricter AI rules
China has embraced open source AI more actively than the United States. Last year, DeepSeek released an open source model that rivaled leading U.S. systems, while companies like Z.ai and Moonshot AI continue to close the gap. Chinese President Xi Jinping has also made open-source AI part of China’s global strategy.
People familiar with internal discussions say OpenAI and Anthropic are worried they are losing their long-held leadership position. Both companies have lobbied Washington for tighter controls, arguing that artificial intelligence models created through illegal distillation pose a national security risk.
What this AI war means for the future
At the same time, nearly 200 Silicon Valley start-ups owned by Xiaozhong Science and Technology Association Urge the Trump administration not to restrict China’s open source artificial intelligence. Now, more technology leaders are openly joining the open source camp.
Support for open source artificial intelligence continues to grow in Silicon Valley. Elon Musk, Mark Zuckerberg and Google CEO Sundar Pichai join Jen-Hsun Huang and Satya Nadella in supporting open models, arguing they are critical to innovation and competition.
The battle over China’s AI has turned the longstanding debate over open versus closed AI into one of Silicon Valley’s biggest battles, with implications for innovation, national security and the future balance of power between China and the United States.
