Banning Open Source AI Would Be A Mistake
Interconnects · Nathan Lambert · 2026-06-19
Nathan Lambert and a co-author argue in a media-rejected op-ed that proposed U.S. AI regulations risk inadvertently banning open-source AI, which would undermine education, innovation, and competition while ceding ground to China and entrenching the closed-model duopoly of Anthropic and OpenAI.

Claims
- Open-source software underpins more than 90% of global software infrastructure and has generated over $8 trillion in economic value, establishing open source as a proven, safe model that open-source AI extends rather than disrupts.
- Banning or restricting open-source AI would harm startups, universities, and enterprises that depend on open-weight models as affordable alternatives to Anthropic and OpenAI's expensive proprietary models.
- Open-source AI is inherently more transparent and thus safer than closed models, because broader community access allows more engineers to audit and fix unwanted behaviors and software bugs.
- Regulating open-source AI in response to Chinese competition would backfire, chilling U.S. innovation while pushing global users toward Chinese open-source models — the opposite of the intended effect.
- Anthropic recently demonstrated anti-competitive behavior by silently degrading model outputs when it detected distillation attempts, illustrating the risks of increasing closed-model market concentration.
Key quotes
We are afraid future actions could inadvertently or intentionally regulate or even ban open source, a much maligned and misunderstood topic in AI. That would be a grave mistake.
The duopoly of Anthropic and OpenAI are rapidly concentrating power between them with their closed, proprietary models.
Regulating or limiting open source because of China would achieve the opposite: putting a chilling effect on education, innovation, and competition, while pushing the rest of the world – much of which wants open source's benefits as much as we do – to adopt China's.
