Monday's AI news is dominated by two threads: the US export ban on Anthropic's top models grinding into its fourth day, and a quietly brutal reckoning for the consulting industry over AI it can't quite control. Here's what actually matters this morning, checked and put in context.

The Anthropic ban rolls on

Three days after the US Commerce Department ordered Anthropic to suspend its newest models — Claude Fable 5 and Mythos 5 — for every foreign national worldwide, the models are still dark for everyone, and Anthropic says it is "working to restore access." The fallout has turned into a sovereignty argument across Europe and a behind-the-scenes story about who pushed for the crackdown.

A neat illustration of how blunt the ban is: as a foreign national, even Rishi Sunak — the former UK prime minister who became a paid senior adviser to Anthropic last October — would, on the face of it, be barred from using the very models he advises on. (That's commentary on the ban's breadth, not a reported incident — but it captures the absurdity of a worldwide-by-nationality rule.)

OpenAI launches a Partner Network

OpenAI today unveiled the OpenAI Partner Network, a $150 million push to build an ecosystem of consultancies, systems integrators and tech partners to deploy its AI inside large organisations. It comes in three tiers, includes a pilot "Forward Deployed Experts" programme, and sets a target of 300,000 certified consultants by the end of 2026.

The timing is pointed. OpenAI is betting big on consultants to roll out enterprise AI in the same week the consulting industry is being publicly embarrassed by it.

The consulting reckoning

That embarrassment is real and growing. KPMG pulled a flagship report on agentic AI after UBS, the NHS, Swiss Federal Railways and Transport for London told the Financial Times its claims about them were fabricated — AI detector GPTZero reportedly found only 5 of 45 citations pointed to real, intact sources. It follows EY pulling a report last month and Deloitte's refund to the Australian government last year.

On the regulatory side, the UK's Financial Reporting Council has already flagged that the Big Four aren't adequately monitoring how AI and automation affect audit quality, and issued dedicated AI-in-audit guidance earlier this year — so regulators are circling the problem, even if the KPMG embarrassment is what's made it visible.

Rio's "homegrown" model looks like a merge

In a smaller but telling story, Rio de Janeiro's city government released a model, Rio 3.5, claiming benchmark wins over Alibaba's Qwen 3.7. Researchers quickly found it was built as a merge of existing models — its configuration lists a Qwen model as its base. To its credit, Rio's tech arm has now acknowledged the merge, said an unfinished version was uploaded by mistake, and apologised. It's a useful reminder to treat "our model beats X" benchmark claims with scepticism — but a much fairer story than a straight gotcha. (More on this shortly.)

The shape of the day

No major new model launches landed overnight — the genuinely-new beats are OpenAI's partner push and the consulting story, against the steady backdrop of the Anthropic ban. We'll update as Monday develops.
