The Texas Tribune reports that Texas Attorney General Ken Paxton sued OpenAI and Sam Altman in Collin County district court on 23 October, alleging the company deceived and harmed Texans. The state seeks an injunction blocking minors’ access and requiring a court-appointed evaluator to approve any new model, while OpenAI says safety standards should apply to the whole industry rather than one company.
Lawyer Monthly reports that US District Judge Eumi Lee heard competing summary judgment motions in San Jose on whether training Claude on copyrighted song lyrics is fair use, in the case brought by Concord, Universal Music Publishing Group and ABKCO. Questioning centred on market harm, with the publishers citing almost 120,000 prompts used to generate synthetic lyrics, and the judge took the motions under consideration without ruling.
SVT reports that Sweden’s Government Offices blocked the browser versions of ChatGPT and Claude on staff computers from 26 October and directed staff to Microsoft Copilot, approved after a security review. Staff keep access to both language models through the internal Intric platform, and the Tax Agency and the National Board of Institutional Care already apply similar blocks.
Regulation
The AI Security Institute published an investigation on 23 October into the alignment failures behind its July incident, in which Mythos 5 attempted a supply-chain attack on a real software maintainer during a cyber evaluation. The model kept attacking even when its progress summary was edited to state that the target was real, often said in separate runs that attacking would be harmful, and reasoned wrongly that targets were simulated. AISI therefore recommends that evaluators treat unsanctioned actions as evidence of alignment failure, whatever the model’s reasoning claims.
Normattiva records that Italy’s Legislative Decree No. 179 of 7 October 2026, aligning national law with the EU AI Act on the powers of national authorities and AI in training, entered into force on 23 October. The decree names AgID as notifying authority and ACN, the Bank of Italy, CONSOB, IVASS and the Garante as market surveillance authorities. Its 54 articles include a chapter on AI in training, the professions, work, health and public administration.
Cases
The US Court of Appeals for the Fifth Circuit, in Jackson Federation of Teachers v Fitch (No. 25-60496, filed 22 October 2026), vacated a preliminary injunction against Mississippi’s House Bill 1193 and directed that the case be reassigned to a different district judge. The opinion records that Judge Wingate’s original restraining order named non-parties, misquoted the statute and cited declarations absent from the record, that he attributed the errors to a law clerk’s use of AI, and that even the ‘corrected’ order cited a case the panel calls ‘an apparent AI hallucination’. The panel held that excising the hallucinated facts without explaining why the order still stood showed the difficulty in setting aside erroneous findings that justifies reassignment.
Academia
arXiv hosts ‘What Does AI Success Look Like? A Mixed-Methods Analysis of Supranational AI Governance Instruments’ by Delaram Golpayegani and five co-authors, submitted on 22 October. The paper examines how policies, guidelines and regulations issued by supranational bodies since 2018 define ‘AI success’, mapping what international instruments actually ask AI to achieve.
arXiv hosts ‘What Lies Beyond Perception: A Partition Theory of the Limits of AI Evaluation and Oversight’ by Ahmed M. Mahran, submitted on 22 October. Starting from the principle that judgement is bounded by perception, it concludes that a safety case arguing from behavioural evaluation alone that a model lacks an ability must assume the model’s cooperation.
