OpenAI reports coordinated model-distillation campaign

On September 30, OpenAI disclosed that it had disrupted a July campaign to extract its models’ protected reasoning through coordinated prompts. The company said a core cluster involved individuals associated with Moonshot AI, while acknowledging uncertainty about whether all observed operators belonged to one group. OpenAI reported banning or restricting accounts, strengthening controls, and sharing findings with industry and government partners. It characterized the activity as a violation of its terms of service; its public account did not establish independent proof of the attribution. [1][2]

Senators introduce bipartisan data-center grid-cost proposal

On September 30, Senators Shelley Moore Capito, Mike Lee, Sheldon Whitehouse and Martin Heinrich introduced the proposed Bipartisan American Affordability and Jobs Act of 2026. The bill would require data centers to pay all associated transmission costs while changing federal permitting and environmental-review procedures for energy infrastructure. The sponsors say the cost provision is intended to prevent grid expenses driven by growing data-center demand from being passed to other customers. The proposal awaits congressional action.[3][4][5]

Newsom vetoes AI clinical-judgment protection bill

On September 30, California Governor Gavin Newsom vetoed AB 2575, a proposed measure that would have protected health-care workers who overrode unsafe AI recommendations when exercising clinical judgment. The California Nurses Association, which backed the bill, criticized the veto and said it would seek similar protections again. The governor's same-day legislative update also lists vetoes of AB 2656, concerning notice when AI performs public employees' work, and SB 903, concerning mental-health professionals and AI. These measures remain unenacted.[6][7]

Connecticut AI law provisions take effect

On October 1, provisions of Connecticut’s Public Act 26-15 took effect, including protections for employees who report frontier-model risks and a framework covering employment decision technology. The main employment-tool information and notice duties apply to tools deployed on or after October 1, 2027. A narrower AI-subscription disclosure rule in Public Act 26-100, § 46, also took effect today after that act repealed Public Act 26-15’s original subscription section. Covered providers of subscription-based generative image, audio or video AI systems with more than one million monthly users must disclose key terms and obtain written consumer acceptance. Companion-chatbot requirements are scheduled for January 2027.[8][9][10]

Senate hearing examines liability for AI-agent attacks

At a September 30 Senate Homeland Security subcommittee hearing, Senator Josh Hawley called for liability rules addressing cyberattacks by AI agents. According to Roll Call, he described planned legislation that would make technology companies liable for reckless agent design and users liable for reckless deployment, and clarify how hacking penalties apply when agents are used to commit crimes. Witnesses discussed existing Federal Trade Commission and tort-law remedies alongside possible new requirements. On October 1, Hawley and Senator Chris Murphy jointly announced the proposed AI Agent Accountability Act. Their announcement says it would extend criminal and civil liability under the Computer Fraud and Abuse Act to AI-agent operators and developers in specified hacking circumstances and permit federal and state attorneys general to seek injunctions. The senators described planned legislation; an introduced bill and final text have not been verified.[11][12]

Court dismisses Chegg and Penske AI Overviews antitrust suits

On September 30, U.S. District Judge Amit P. Mehta granted Google's motions to dismiss antitrust suits brought by Chegg and Penske Media Corporation over AI Overviews. The court held that the publishers had not plausibly alleged an agreement exchanging their content for Google search referrals, rejected Penske's claim that AI Overviews was a separate tied product, and found defects in the remaining antitrust theories. It declined supplemental jurisdiction over their California unjust-enrichment claims. The Penske dismissal is without prejudice and is a final, appealable order.[13][14]

In submissions to an Australian parliamentary AI inquiry reported October 1, Anthropic urged conditional permission for AI developers to train on copyrighted works through an opt-out approach after the government ruled out a broad text-and-data-mining exemption. Public broadcasters ABC and SBS opposed weaker copyright protections and urged rules requiring AI services to compensate news publishers. These are stakeholder proposals in the inquiry, which is due to report in November.[15][16]

Khanna asks AI firms about attempted model-weight access

In letters dated September 30 and reported October 1, Representative Ro Khanna asked OpenAI, Anthropic, Google, Meta and SpaceXAI for information about known attempts by China or other hostile actors to obtain their AI model weights without authorization and about safeguards against such access. Reuters reviewed the letters and interviewed Khanna. The request adds congressional scrutiny of frontier-model security; it is an information request, and Reuters reported few known cases of model-weight theft.[19]
