Anthropic AI ban enters its second week

Anthropic's Fable 5 and Mythos 5 have been switched off for foreign users for eight days. The promise of restoration 'within days' has not been kept.

Key takeaway

Washington switched off a major AI firm's models on security grounds while its identically-flawed rival stayed on sale.

Anthropic's Fable 5 and Mythos 5 models have now been suspended for roughly eight days, after Commerce Secretary Howard Lutnick ordered the company to bar foreign nationals from access on 12 June. Anthropic is a US AI developer; the two models power its consumer and frontier products. The promise that service would return "within days" has not been kept. Senior Anthropic staff met Department of Commerce officials in Washington this week to negotiate, House members publicly demanded answers on 18 June, and President Trump, at the G7 summit of advanced economies, said the talks were "going fine"⁠1.

Lutnick's letter cited the risk of military-intelligence use by China and Russia. Axios reported a different sequence: relations ruptured after Anthropic refused to let the US military use its models for domestic surveillance and fully autonomous weapons, and the government then placed the company on a national-security blacklist⁠2. Anthropic counters that OpenAI's GPT-5.5 carries the identical jailbreak vulnerability and remains on public sale. A security action that hits one lab and spares its rival, after that lab funded a pro-regulation campaign, reads to critics as political retaliation rather than threat mitigation. Lutnick's office maintains the same export-control rule would apply to any vendor carrying the vulnerability.

The rupture went transatlantic. The G7 summit at Evian, held 15 to 17 June, failed to reverse the controls⁠3. European governments arrived unsettled that a model they had deployed could be turned off worldwide by one letter, with no appeal and no notice to customers. Brussels has folded the episode into its European Technological Sovereignty Package, presented on 3 June, which bundles a chips programme with a Cloud and AI Development Act meant to wean the bloc off US infrastructure. A UK exemption was sought at Evian and refused.

Deep Analysis

In plain English

Anthropic makes two powerful AI models called Fable 5 and Mythos 5. On 12 June, the US government ordered Anthropic to stop letting people outside the US use them. The suspension has now lasted more than a week. Axios reported that the real reason is a falling-out: the US government wanted to use Anthropic's AI for domestic surveillance and to control autonomous weapons, and Anthropic refused. The government then put Anthropic on a national-security blacklist. Anthropic has pointed out that a rival product, OpenAI's GPT-5.5, has the same security flaw the government cited; and GPT-5.5 is still available. The G7 leaders met in France and could not agree on a way to reverse the US controls.

Deep Analysis
Root Causes

The Anthropic suspension reflects two underlying structural tensions that predate this specific action.

First, the 2018 Export Administration Regulations (EAR) give the Commerce Department broad authority to restrict technology transfers to foreign nationals without defining AI-specific thresholds. Commerce's application of EAR to a software-as-a-service model; where the 'transfer' is API access, not physical export; is legally novel and untested in federal court. The government is using a regulatory framework designed for hardware and encryption to control AI model access.

Second, the Anthropic case makes visible a structural conflict between the national-security state's demand for exclusive control over frontier AI capabilities and the commercial model of frontier AI firms, which depends on broad access (including international researchers and enterprise customers) to generate the revenue that funds further model development. These two interests cannot both be satisfied simultaneously.

What could happen next?
  • Precedent

    A sustained suspension of a major US frontier AI model on national-security grounds would establish that the US executive can effectively nationalise AI access as a geopolitical tool, prompting European governments to accelerate sovereign AI model development.

    Medium term · Assessed
  • Risk

    If courts reject Commerce's EAR application to SaaS API access, the legal basis for AI export controls collapses, leaving the government with no standing mechanism to enforce similar restrictions on future refusals.

    Short term · Reported
  • Consequence

    Anthropic's identification of GPT-5.5's identical jailbreak as a public counter-argument establishes an asymmetry precedent: competitors who maintain government relationships are not subject to the same access restrictions regardless of their security posture.

Different Perspectives
Russia
Russia
Russia vetoed the same renewal on 17 September, arguing that Britain, France and Germany never validly triggered the snapback that reimposed the pre-2015 UN resolutions. No panel was ever seated under that mandate, so the UN list decays fastest for states that screen against it rather than against the American one.
China
China
China vetoed renewal of the UN sanctions monitoring mandate on 17 September, arguing that Resolution 2231 terminated on 18 October 2025 and that the Security Council should drop Iran's nuclear file altogether. On that reading there is nothing to monitor, so the sanctions survive and their enforcement does not.
Iraq
Iraq
Baghdad saw the last American counter-Islamic State troops leave its territory on 30 September, completing a timetable it agreed with Washington in September 2024. Iraqi airspace deconfliction passes to Baghdad, which still has an open inquiry into the Maysan drone launches that has named nobody.
Pakistan
Pakistan
Treasury names Waseem Pasha Tajammal of Rawalpindi as the Cavalier group's chairman and places one of the designated incorporations in Islamabad. QatarEnergy separately told Pakistan that liquefied natural gas cargo cancellations would run through November, so Islamabad carries an enforcement question and a supply gap at once.
Turkey
Turkey
Treasury named a Cavalier Dynamics company incorporated in Istanbul among the ten nodes it designated on 29 September, and Ankara has published no response. Turkey imported a record 120,000 barrels a day of Indian diesel in August, cutting Russia's share of its diesel imports to 20 per cent.
India
India
Suraj Yadav, a wiper from Uttar Pradesh, was killed aboard the Cape Dao on 23 September, and 19 of the ship's 20 Indian crew were taken off alive. India's September imports ran at 575,000 barrels a day from Iraq and 566,000 from Saudi Arabia, back to pre-conflict rates.
