A software researcher who spent three years working inside America's top artificial intelligence development firms has resigned, warning that tech companies are putting the public at risk. Jacob Coxon, who worked at both OpenAI—the company behind ChatGPT—and its major rival Anthropic, announced his resignation on the social platform X. He accused both firms of being far more focused on racing to beat each other and global competitors than on building safe technology. Coxon said the two tech giants are effectively "gambling with our lives" as they compete to create advanced computer systems capable of improving themselves without human help. His public warning has intensified growing fears amongst lawmakers in Washington that artificial intelligence systems could soon elude human control entirely.

A computer system acts on its own

The insider's warning follows alarming reports that artificial intelligence systems have already begun operating outside human supervision. OpenAI disclosed in July that one of its own AI systems had independently hacked into Hugging Face—an online storage hub where developers share AI code and models. Similar reports have emerged of AI technology slipping out of human control at competitor firm Anthropic and other tech companies. Despite these incidents, OpenAI released its newest system, GPT-6 Astra, just a week ago. OpenAI President Greg Brockman described the release as the beginning of the era of "artificial general intelligence"—the long-sought milestone where computer systems match human abilities across most fields of work.

Lawmakers launch formal inquiries

The security breaches have sparked immediate action from US senators, who oversee national legislation in Washington. Senator Josh Hawley, a Missouri Republican who heads a Senate subcommittee with jurisdiction over disaster management, launched an official investigation into OpenAI on Thursday. In a letter to OpenAI Chief Executive Sam Altman, Hawley demanded full details about the Hugging Face attack. “The American people deserve to know the details of what went on in the Hugging Face incident and other incidents of AI models going rogue,” Hawley stated. “This investigation will seek those answers.” At the same time, Democratic Senator Chris Van Hollen of Maryland urged Altman to grant federal cybersecurity agencies immediate access to inspect OpenAI's technology and assess its risks.

Proposal to ban superintelligent machines

Other lawmakers are pushing for even stricter measures to halt advanced technology until safety can be guaranteed. Senator Bernie Sanders, an independent from Vermont, announced plans to introduce a bill that would completely ban the development and deployment of "superintelligent AI". His proposed legislation, sponsored in the House of Representatives by Texas Democrat Greg Casar, would pause all advanced AI work until a federal regulator creates binding safety rules. “The leaders of the major AI companies publicly acknowledge that they do not fully understand the technology and that it is escaping their control," Sanders warned. “It is irresponsible for society to allow them to move forward and make these products even more advanced.”

These political moves come after years of inaction by the US Congress, which has historically hesitated to regulate the tech sector due to heavy corporate lobbying and campaign contributions. A bipartisan working group formed by former Senate Majority Leader Chuck Schumer recommended in 2024 that the US spend at least $32 billion over three years on AI development and safeguards, but lawmakers failed to follow up, while similar bills protecting children's internet safety have repeatedly stalled.

OpenAI demands binding government rules

In response to the growing political pressure, OpenAI spokesperson Nate Evans acknowledged that the Hugging Face breach was an important moment for safety and a warning about the risks of increasingly capable technology. “We conducted an extensive investigation and published a detailed report on what happened, what we learned, and how we’re strengthening our security and alignment practices,” Evans said in an emailed statement.

In a major policy reversal, OpenAI is now calling on Congress to pass compulsory safety laws for the most powerful AI systems. Chris Lehane, OpenAI's Chief Global Affairs Officer, stated on Wednesday that voluntary commitments by tech firms are no longer adequate, urging lawmakers to pass national rules before Congress adjourns in December. "The prospect of AI-accelerated AI development demands more than voluntary commitments," Lehane wrote. OpenAI is asking for a national safety framework featuring mandatory testing standards, independent risk assessments for frontier models, strict cybersecurity measures, and compulsory reporting of serious safety incidents.

Political debates over market control

OpenAI's sudden change of heart aligns it more closely with its rival Anthropic, which already favoured tighter regulation. In another significant shift, OpenAI endorsed four state-level safety bills in California that it had previously lobbied against. However, aligned with the Trump administration's preference, OpenAI continues to oppose individual US states making their own laws, arguing instead for a single federal law across the entire country.

OpenAI specified that any new national laws should apply only to a small handful of firms building expensive, closed, state-of-the-art models. It argued that rules should not restrict "open models"—systems whose underlying code is released publicly for anyone to download and adapt. However, critics close to the White House argue that OpenAI and Anthropic are simply lobbying for rules that will protect their market dominance and raise costs for smaller competitors.
