Some of the world’s largest technology companies have come together to send a strong message to U.S. lawmakers: open-source artificial intelligence should remain open.
The coalition, which includes Nvidia, Microsoft, Meta, IBM, AMD, Dell Technologies and several other major players in the AI industry, has signed an open letter urging the U.S. government not to introduce sweeping restrictions on open AI models. The companies argue that open-source AI is one of the biggest drivers of innovation, competition and economic growth, and that limiting access could slow America’s progress in one of the world’s most important technologies.
The letter comes at a time when governments around the world are debating how AI should be regulated. As artificial intelligence becomes more powerful and capable of performing increasingly complex tasks, concerns about safety, cybersecurity, misinformation and national security have prompted calls for stricter oversight. However, the companies behind the letter believe regulations should be carefully targeted rather than broad enough to discourage innovation.
Open-source AI refers to artificial intelligence models whose core software or “weights” are made publicly available. This allows developers, researchers, businesses and universities to study how the models work, improve them and build new applications without relying entirely on one company.
This approach has helped accelerate AI development over the past few years. Thousands of developers around the world have used open AI models to create chatbots, coding assistants, medical research tools, educational platforms, language translators and business applications.
Supporters say open-source AI encourages collaboration because anyone can contribute improvements, identify weaknesses and develop new ideas.
By contrast, closed AI models are controlled entirely by the companies that build them. Users can access these systems through online services, but they cannot inspect or modify the underlying technology.
The companies behind the letter believe open AI provides several important advantages.
First, it increases competition. Smaller startups can build AI products without spending billions of dollars creating models from scratch. This reduces the dominance of a few large companies and encourages innovation across the industry.
Second, businesses benefit from greater flexibility. Instead of depending on a single AI provider, organisations can customise open models for their own needs while keeping sensitive information within their own systems.
Third, researchers believe openness actually strengthens security. Since thousands of experts can examine open models, flaws and vulnerabilities can often be identified and fixed more quickly than in closed systems where only the developer has access.
The coalition argues that transparency leads to stronger and more reliable AI over time.
Despite these benefits, governments remain concerned about the risks associated with advanced AI.
Powerful models could potentially be used to launch cyberattacks, generate convincing misinformation, assist criminals or create harmful automated systems if they fall into the wrong hands.
Some policymakers have proposed requiring advanced AI systems to include emergency shutdown mechanisms, sometimes referred to as “kill switches,” while others have suggested placing tighter controls on the release of highly capable open-source models.
The companies acknowledge these concerns but argue that banning or heavily restricting open AI would not eliminate the risks.
Instead, they believe bad actors would simply move their activities elsewhere, while legitimate researchers and businesses would face unnecessary obstacles.
Another major issue influencing the debate is international competition.
The United States is engaged in an increasingly intense race with China to become the global leader in artificial intelligence.
Technology executives argue that keeping AI development open allows American universities, startups and companies to innovate more quickly and maintain a competitive edge.
They warn that excessive regulation could unintentionally slow U.S. progress while competitors in other countries continue developing advanced AI technologies with fewer restrictions.
The coalition also supports stronger enforcement against intellectual property theft and the illegal use of American technology by foreign organisations rather than imposing blanket restrictions on all developers.
Rather than opposing regulation entirely, the companies are calling for balanced rules.
They support laws that punish the misuse of AI, improve cybersecurity, protect intellectual property and ensure developers build responsible systems.
However, they believe regulations should focus on preventing harmful behaviour instead of restricting access to open technology itself.
According to the letter, innovation and safety should work together rather than being treated as competing goals.
The debate over open-source AI is expected to play a major role in shaping the future of artificial intelligence.
As governments introduce new AI policies, they must decide how to balance innovation, national security, economic growth and public safety.
For Nvidia, Microsoft and the other companies behind the letter, the answer is clear: open-source AI has been one of the biggest reasons for the rapid progress seen in recent years, and preserving that openness will help ensure that AI continues to benefit businesses, researchers and society as a whole.
The decisions made over the coming months could influence not only the future of the AI industry in the United States but also the global direction of artificial intelligence development for years to come.
