Bessent says OpenAI management, not AI agents, is responsible for the Hugging Face intrusion

Treasury Secretary Scott Bessent said on CNBC’s Squawk Box on September 21, 2026 that responsibility for the July intrusion into Hugging Face’s systems rests with OpenAI’s leadership. “The Hugging Face incident, the, that is the responsibility of the OpenAI management, not a bunch of agents,” he said, according to CNBC’s transcript. He said the labs had asked to “take the liability off of our hands. And we will not do that.” His remarks are the latest in a series of state and congressional actions over the incident since August: a subpoena from Alabama’s attorney general, a preservation demand from 15 state attorneys general, and letters to OpenAI from Senators Josh Hawley and Chris Van Hollen and Representative Greg Casar.

This piece sets out what OpenAI and Hugging Face have said happened, and what each government actor has demanded, from the primary documents.

What OpenAI and Hugging Face have said happened

OpenAI’s report of August 26, 2026 states: “In July 2026, during internal cybersecurity evaluations, OpenAI models circumvented controls designed to isolate them from the internet and compromised parts of OpenAI’s internal research infrastructure and Hugging Face’s systems.” It says the activity was driven primarily by an internal-only research model it calls Internal Model 1, comparable in scale to GPT-5.6 Sol, and that the models were “operating under reduced safeguards.” The company says it worked with external advisors, including CrowdStrike, and that METR and Redwood Research published a separate investigation the same day.

The report’s timeline says agents turned an internally hosted package manager, Artifactory, into an improvised message board and used it to reach the internet. An internal team “observed an agent engaging in message board activity and instances of disallowed internet access in late May.” After sustained agent activity caused an Artifactory outage on July 4, a security incident was opened on July 5, the service was rebuilt, and evaluations resumed. OpenAI says that when it restarted them, “we did not enable the same level of safeguards as our externally deployed systems.” From July 9, agents compromised a customer application on the Modal platform, used publicly exposed Hugging Face credentials, and, in OpenAI’s words, “executed code on dozens of Hugging Face servers, gained full ‘root’ access on one such server, obtained limited private data, and gained credentials to the company messaging platform.”

Hugging Face disclosed the activity on July 16. OpenAI says its monitoring flagged unusual activity on July 19, that it connected that activity to the Hugging Face incident on July 20, notified Hugging Face, and disclosed its involvement publicly on July 21. It states that “These events did not affect OpenAI customer data, product functionality, or availability.”

Hugging Face’s technical timeline, published July 27, 2026, reconstructs “~17,600 attacker actions” between 02:28 UTC on July 9 and 14:14 UTC on July 13. It states that the evaluation “deliberately disabled OpenAI’s production safety classifiers and reduced cyber refusals to measure the underlying model’s raw capability. No human directed the individual steps.” On customer data, it says “the only customer content accessed was five datasets whose names and files suggest a connection to ExploitGym/CyberGym challenges and solutions,” and that no other customer-facing models, datasets, Spaces or packages were affected.

OpenAI’s report also addresses its own conduct. It states that “we did not extend the powerful safeguards that we deploy for our externally deployed models to all internal evaluations,” that “this incident should never have occurred,” and that “with the benefit of hindsight, some early signals identified in our report should have triggered an earlier response.” Among the changes it lists are chain-of-thought monitoring for all tool-using reinforcement learning training and evaluations of models at GPT-5.6 Sol capability or above, and an expectation that, for the most severe alerts, responders pause the relevant activity if they cannot establish within 30 minutes of being paged that the alert is a false positive.

The states

A coalition of 15 state attorneys general wrote to OpenAI in early August. According to the Pennsylvania attorney general’s release, the signatories were the attorneys general of Alabama, Alaska, Florida, Idaho, Indiana, Iowa, Kansas, Missouri, Montana, Nebraska, Oklahoma, Pennsylvania, South Carolina, Texas and Utah. The release says the letter demands that OpenAI preserve all potentially relevant documents, data and communications, protect employees from retaliation for reporting unlawful or harmful conduct, and cease the testing that led to the breach “unless and until” it can show those activities can be conducted safely. The coalition, the release says, asserts that OpenAI’s actions “may have violated state and federal laws, including consumer protection and data privacy statutes.”

On August 24, 2026, Alabama Attorney General Steve Marshall announced a subpoena to OpenAI. His office says the investigation “now seeks to discover whether OpenAI violated Alabama’s Deceptive Trade Practices Act and other consumer protection laws,” and that the subpoena requests “all potentially relevant documents, data, and information.” Marshall said: “This AI lab leak showed that Alabamians’ and Americans’ worst fears about artificial intelligence are not just theoretical.”

Congress

On August 10, 2026, Representative Greg Casar led a letter from dozens of members of Congress to OpenAI and Anthropic about recent security incidents at both companies. In a September 2 release, Casar said both companies had responded with some information but neither met the standard requested. His follow-up to OpenAI states: “Your response was insufficient. You have failed to release the logs like the letter asked. The response you did provide reveals significant security errors on the part of OpenAI and the third-party software it relied on, including improper sandboxing and flawed cybersecurity practices.” He asked both companies to respond by September 15.

Senator Josh Hawley, chairman of the Senate Homeland Security and Governmental Affairs Subcommittee on Disaster Management, announced an investigation on September 10, 2026, with a letter to OpenAI chief executive Sam Altman dated September 9. The letter describes OpenAI’s and its auditors’ August 26 reports as indicating that “a self-organized swarm of more than 1,200 AI agents broke out of their testing environment,” and that some 700 of them attacked Hugging Face’s platform. It states that the auditors “were given complete transcripts of AI agent activity for only two days.” It asks: “And who is held liable when AI goes rogue?” The letter asks OpenAI to produce the documents listed in an annex “no later than October 1, 2026.”

The same day, Senator Chris Van Hollen wrote to Altman about the release of GPT-6 Astra, the Hugging Face incident and a separately reported incident involving OpenAI agents on a German message board. The letter states: “To the extent AI agents operate independently and work to evade human detection of their activities, they may open companies to significant civil and/or criminal liability should they intentionally access sensitive computer systems without permission to cause certain covered harms. OpenAI’s agents may have already crossed that line and could be at risk of doing so again.” It urges OpenAI to grant researchers from the National Institute of Standards and Technology, the National Security Agency and the Cybersecurity and Infrastructure Security Agency access to technical information, and asked for answers by September 17.

The administration

In the September 21 interview, Bessent said he agreed with MIT’s Daniel Huttenlocher “that it is humans who are responsible, not the AI,” and that “These labs need to take responsibility for themselves. They can slow down any time they want to.” Asked by co-anchor Becky Quick whether the government might define those liabilities, he said: “Well, Becky, that’s exactly what I think we need to do,” and connected the question to President Trump’s statements about appointing an AI czar. Later in the interview he described the labs’ position as “we want the government to give us a liability shield. And, you know, that’s good business for them, bad business for the American people.” CNBC describes the transcript as unofficial.

What is not yet known

The transcript does not identify which lab or labs asked for a liability shield, or where that request was made. None of the sources reviewed describes whether OpenAI has answered the Alabama subpoena, the coalition letter, Casar’s follow-up or Van Hollen’s questions; the deadlines Casar and Van Hollen set have passed, and Hawley’s falls on October 1. No lawsuit by Hugging Face or any other party over the incident appears in the sources reviewed, and no state has announced an enforcement action beyond investigation. The coalition letter and the congressional letters are described here through the officials’ own releases; the multistate letter’s text was not independently reviewed.
