Lawmakers Propose Ban Artificial Superintelligence Act to Halt Advanced AI Development
Senator Bernie Sanders and Representative Greg Casar introduced the Ban Artificial Superintelligence Act in early September 2026, seeking to prohibit the development of AI systems that exceed human-level intelligence across most domains. The bill comes days after OpenAI released GPT-6 Astra, its most capable model to date.
Senator Bernie Sanders and Representative Greg Casar introduced the Ban Artificial Superintelligence Act in early September 2026, seeking to prohibit the development of AI systems that exceed human-level intelligence across most domains.
The bill comes days after OpenAI released GPT-6 Astra, its most capable model to date. Astra was the first AI model to reach a "Critical" cybersecurity capability threshold under OpenAI's own safety framework, meaning it can independently identify and exploit vulnerabilities in hardened computer systems.
The proposed legislation would pause certain categories of advanced AI research and prohibit the development of systems that meet the definition of artificial superintelligence. The bill does not define a specific technical threshold but directs federal agencies to establish one.
Supporters of the bill argue that the pace of AI development has outrun the ability of governments and institutions to assess the risks. They point to the rapid progression from GPT-4 to GPT-6 Astra in just a few years as evidence that the technology is advancing faster than expected.
Opponents, including many AI researchers and technology companies, say the bill is too broad and would put the United States at a competitive disadvantage relative to China and other countries that are not slowing their AI programs.
OpenAI, which released Astra on September 3, 2026, implemented several safety measures alongside the launch. The public version of the model is designed to refuse requests to generate exploit code, and enterprise access is disabled by default.
The bill faces an uncertain path in Congress. Similar proposals to regulate advanced AI have stalled in previous sessions, and the technology industry has significant lobbying resources to oppose restrictions.
The debate over AI regulation has intensified in 2026 as models have become more capable and autonomous AI agents have begun to appear in commercial products.
