Frontier open-source and open-weight LLMs should be heavily regulated

Powerful model weights without control create a safety gap that policy cannot close fast enough.

Open Source and Open Weight Large Language Models (LLMs) should be banned and heavily regulated. [1]

Not because openness is “bad”, but because releasing powerful model weights without control creates a safety gap that policy and law enforcement cannot close fast enough. [2]

Graphic on open-weight LLM risk and regulation — Open-weight LLM risk

Here is the uncomfortable part: these systems can be misused at scale, both intentionally and unintentionally. [2][3]

Criminals can use them for identity theft, impersonation, blackmail, and fraud. [2]
Hackers and cybercrime groups can scale phishing, social engineering, and cyberattacks, especially when safeguards are removed from open-weight models. [2]
Dictators and state actors can use them for propaganda, censorship, and mass persuasion. [4][5]
Terrorists and violent extremists could exploit biology-related assistance that lowers barriers to harmful planning. [3][6]
Criminal networks could use chemistry-related help for illicit drug production or handling dangerous substances. [3]
Bullies can amplify harassment and targeted humiliation at scale. [2]

We already accept that high-risk capabilities are restricted.

Nuclear technology is tightly governed under the International Atomic Energy Agency (IAEA) and the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). [7]
Chemical weapons are banned under the Chemical Weapons Convention (CWC), enforced by the Organisation for the Prohibition of Chemical Weapons (OPCW). [8]
Chemical and biological precursors are controlled through export regimes like the Australia Group (AG). [9]
In everyday life, we lock up weapons and keep dangerous products away from children.

Prominent voices have warned about open release of frontier systems.

Dame Wendy Hall, United Nations adviser on Artificial Intelligence, called open sourcing Artificial General Intelligence (AGI) before regulation “really very scary”. [1]
Yoshua Bengio, Turing Award laureate, has argued that catastrophic risk justifies restricting access to the most dangerous systems. [6]
Geoffrey Hinton, AI pioneer, has warned that advanced Artificial Intelligence can be misused and requires serious regulation. [5]
The United Kingdom Artificial Intelligence Safety Institute (UK AISI) has warned that safeguards can be removed quickly from open-weight models. [2]
OpenAI has supported banning access to certain People’s Republic of China (PRC) affiliated models on national security grounds. [10]

My take: we should treat frontier open-source and open-weight LLMs like other high-consequence technologies: licensed access, controlled distribution, mandatory evaluation, and accountability.
