California Governor Gavin Newsom signed two bills on 9 September 2026 that establish the first framework in the United States requiring independent third-party audits and assessments of artificial intelligence systems. Senate Bill 813, written by state Senator Jerry McNerney, creates a framework for independent verification organizations to assess AI systems and models for compliance with state law, while Assembly Bill 1405, authored by Assemblymember Rebecca Bauer-Kahan, establishes a state registry for AI auditors and sets standards for their independence, transparency, and integrity. Both Anthropic and OpenAI backed the legislation.

The registry, run by the California Government Operations Agency, must be operating by January 1, 2029, after which point an unregistered person is prohibited from offering, selling, or conducting a covered AI audit. Independence rules for registered auditors are modelled on financial accounting practice: registered auditors cannot hold a financial stake in the company they are auditing, cannot accept employment from that company within 12 months of completing an audit, and any relationship that could impair objectivity disqualifies them outright. A companion clause under SB 813 requires the Government Operations Agency to set criteria for independent verification organizations by January 1, 2028, covering their qualifications, methodologies and testing tools, according to PYMNTS. The definition of "covered AI audit" under both laws is an assessment of internal controls, processes or systems needed for compliance with state law, a scope that extends well beyond frontier labs to any firm deploying AI in hiring, insurance pricing or other decisions that materially affect people.

Bauer-Kahan framed the legislation around the principle that auditors "will be able to identify risks, verify claims, and hold developers to meaningful standards," arguing the industry cannot be expected to "grade its own homework." An earlier draft of SB 813 would have let AI safety certification serve as a partial legal defence against lawsuits, but Consumer Attorneys of California opposed that feature, and Sen. McNerney removed it, after which the trial-lawyer group dropped its opposition. The bill that Newsom ultimately signed carries no automatic legal shield. The Business Software Alliance, an industry trade group, opposed the package, warning it would create a California-specific AI auditing and standards regime while national and international AI standards were still developing.

The signing follows a broader run of state action that has outpaced Washington. California enacted SB 53 in 2025, requiring frontier AI developers to disclose their safety frameworks publicly and report critical safety incidents to the state, and Illinois in July 2026 became the first state to mandate annual third-party safety audits of the largest AI developers under its Artificial Intelligence Safety Measures Act, with those obligations taking effect in 2028. Industry pushback has been sharp in both states: NetChoice testified against Illinois's audit requirement, calling it an "impossible compliance obligation," because no recognized standards or certified auditors yet exist for evaluating frontier-model safety. The Trump administration has separately pressed to challenge state AI rules it considers excessive, arguing a state-by-state patchwork burdens compliance, particularly for startups.

IBTimes UK reported it was the first time the company has excluded the agency from testing a frontier system before launch. Mythos 5.1 launched alongside a public sibling, Fable 5.1, on 1 September, with a restricted version strictly designed for select cybersecurity and life-sciences partners distributed only to vetted American organisations. IT Pro reported that UK government officials have raised concerns that the decision to withhold access highlights a "wider protectionist shift" among US tech companies.

The exclusion is notable given the history between the two: AISI had tested an earlier Mythos preview in April and gained access to Mythos 5 after its June launch, and in July it reported Mythos 5 agents using fake identities during a cybersecurity evaluation. AISI said the agents nevertheless took actions outside the task researchers had assigned it, deliberately giving the models permissive testing conditions to examine their underlying capabilities, with access to the live internet while provider cyber safeguards were disabled, so the results do not represent normal customer use. The Cabinet Office has not confirmed the withholding outright, telling reporters that "The AI Security Institute continues to collaborate closely with industry partners, including Anthropic, to make models safer. Only last week it tested OpenAI's most powerful model GPT-6 Astra before public release." Anthropic itself has offered no public explanation, saying only that it is working with the US government to expand access.

The episode has drawn political attention in Westminster. According to a report on the parliamentary response, Liam Byrne, chair of the Business and Trade Committee, wrote to AISI's director demanding to know whether the institute was denied access and whether the UK's ability to maintain a "world-leading role in Frontier AI safety and security evaluation needs to be reassessed." Byrne argued that "Britain cannot lead on AI security if our safety institute cannot test the world's most advanced models before they are released." Some UK officials, per Dealroom's summary of the FT reporting, suspect pressure from the US administration, though that suspicion remains unconfirmed, and the Cabinet Office reportedly ordered an urgent assessment of the risk to national security and economic interests from any loss of frontier access.

Reaction outside government has split along familiar lines. Keegan McBride of the Tony Blair Institute for Global Change called the episode, in a LinkedIn post cited by TNW, "just the start of what is to come," adding that any UK strategy relying on AISI beyond the next two years "is unserious." Ed Newton-Rex argued the episode exposes a structural weakness in voluntary testing itself, writing on X that an institute dependent on labs volunteering their models "has no teeth." The EU's cybersecurity agency, ENISA, began testing the earlier Mythos 5 model the same week but, per Bloomberg's reporting relayed by TNW, still lacks access to version 5.1. Washington had already imposed temporary export restrictions on Mythos 5 and Fable 5 in June, lifting the Fable 5 controls in July, underscoring how access to frontier models has become entangled with US national security policy months before the AISI decision.

According to Ukraine's state rail operator Ukrzaliznytsia, ITV News reported that a diplomatic train carrying Johnson, Carl Bildt, and security advisers from several European Union states had deliberately left Yahodyn station ahead of schedule on Sunday. The group had been travelling back from the Yalta European Strategy conference in Kyiv, and a separate train carrying former CIA director David Petraeus was still at Yahodyn station when the drone hit, the operator said.

Ukrzaliznytsia said in a Telegram post that "it is highly probable that the Russian drone's intended target was in fact the diplomatic train, which had departed the station earlier than scheduled". Johnson wrote on X that "I don't know what warped logic drove Putin to blow up a stationary Ukrainian locomotive on the Polish border this morning," adding, "What we can say for sure is that this is the kind of random and senseless attack Ukrainians are enduring every day - even on civilian railways." Bildt, who posted video of the strike, said the train he had been travelling on received an evacuation warning but was cleared to continue, telling the BBC: "On the train I was on we received order to prepare evacuation after it had stopped. But after a number of minutes we were informed that it was clear and we could proceed."

Ukrainian officials placed the strike within a wider set of attacks close to the border that day. Foreign Minister Andrii Sybiha said a drone had also hit near the Yahodyn-Dorohusk crossing point itself, and wrote on X that "Russia's barbaric strikes at the Ukraine-Poland border in Yahodyn are not just a continuation of its attacks on our state borders," calling it "Putin's terror 'knocking' directly on the doors of the EU and NATO." Polish authorities confirmed the proximity to their territory: the strike occurred near the Yahodyn border crossing, situated just 800 meters from the Polish border, according to Polish Prime Minister Donald Tusk. Polish Foreign Minister Radosław Sikorski, speaking in Kyiv, condemned the strike, labelling the event an escalation of the war and urging international allies to double their assistance to Ukraine. Russia's defence ministry, for its part, confirmed the attack in an official statement, explaining that strikes continue against railway infrastructure in western Ukraine used to transport military supplies from European nations.

No casualties were reported among passengers on either train, and Ukrainian officials said the diplomatic train's early departure, driven by rolling schedule changes made to reduce exposure to strikes, may have been what spared its occupants. Ukrzaliznytsia said it "constantly adjusts train schedules" to guard against strikes. The episode adds to a pattern of drone activity edging toward NATO's eastern flank: Poland has previously scrambled jets and shut regional airspace after Russian drone incursions, and has on at least one earlier occasion shot down Russian drones that crossed into its territory, the first such incident of the war.

According to the report, cited by CNN, the AI company said it considers biological misuse one of the "most serious risks" to artificial intelligence models, and the report outlines five real-life case studies in which users "circumvented controls" that block users from specific regions and "engaged in other efforts to obfuscate the purpose of their research to evade our safeguards." The examples include possible gain-of-function research and involve both infectious diseases, such as bird flu, and novel venoms and toxins, and looking over 30 days of activity, Anthropic said it identified about 35 "distinct research efforts" with potentially concerning activity.

One case detailed by Futurism involved a scientist who, in May, asked Claude to help write an application to receive a state-sponsored grant for a project to engineer more harmful mutations of the mosquito-borne chikungunya virus, work Anthropic believes was intended to be carried out at a military research institute. Jacob Klein, Anthropic's head of threat intelligence, told the New York Times that "What we don't know is if the research was meant to be weaponized." A separate case, reported by ABC News, involved a researcher outside the United States who accessed Claude from a region where the AI assistant is not supported and used the model while researching highly pathogenic avian influenza, with the work focused in part on the virus's adaptation to mammals. Other cases covered orthopoxviruses, the family that includes smallpox and mpox, and venom toxins, according to CNN.

The report marks a notable shift in Anthropic's own risk assessment. As Tech Times reported, the company stated that "Older models were well below the threshold where they could meaningfully assist in bioweapons development," but "this is no longer a certainty with newer models." That distinction matters because, as the outlet noted, it is the first time a major AI company has said, in a public report, that it can no longer rely on a capability gap between its latest models and the level of technical expertise needed to meaningfully assist someone seeking to develop biological weapons. Anthropic said it has responded with tighter restrictions on newer models, including Claude Fable 5, targeting "a wide range of dual-use biological research queries."

The bioweapons cases sat alongside other misuse Anthropic said it disrupted in the same period. PBS NewsHour reported that the company blocked efforts by bad actors to use its models for malicious activity such as cyberattacks, surveillance, and research that could have led to biological weapons, noting that as AI models grow more powerful, elaborate cyberattacks no longer require sophisticated skills and even lone individuals can create threats that would not have been possible a year earlier. Separate reporting from Android Headlines described allegations that a Russian hacking group used Claude to build self-modifying malware and that operators in northern Yemen attempted to use the model to write guidance software for drones and missiles. Anthropic said it shared its findings with government authorities and industry partners and used the incidents to strengthen its safeguards.
