Quick Read: Microsoft launched seven new MAI models at Build 2026, including MAI-Thinking-1, its first in-house reasoning model, and unveiled Majorana 2, a quantum chip with qubits 1,000x more reliable than the previous generation. Trump signed an executive order asking AI firms to voluntarily submit frontier models for government review up to 30 days before public release. OpenAI offered nine UK banks access to GPT-5.5 Cyber after Anthropic kept Claude Mythos restricted - Lloyds, HSBC and Nationwide among those gaining access. Nvidia unveiled the RTX Spark chip at Computex 2026, billing it as the reinvention of the personal computer.
Today's AI landscape sits at the intersection of hardware ambition, governance anxiety, and the widening gap between AI strategy and AI reality. Microsoft went big at Build 2026 with seven new models and a bet on agentic PCs. Trump signed a voluntary AI safety order that is already drawing criticism from both sides. And UK banks are navigating a two-tier cyber AI market where the most powerful tool remains out of reach.
Microsoft Build 2026: Seven new MAI models, autonomous workplace agents, and a quantum leap
Microsoft used its annual developer conference in San Francisco to announce what it called a new era of agentic computing. The headline was seven new MAI models, including MAI-Thinking-1 - its first in-house reasoning model - and an expanded agentic platform that can deploy across Microsoft 365, Teams, GitHub Copilot, and Azure Foundry with a single build.
The conference also unveiled Majorana 2, a next-generation quantum chip where qubits are now 1,000x more reliable than the previous generation and capable of maintaining quantum state for up to 20 seconds, compared to microseconds in most competing approaches. Microsoft says a commercially relevant scalable quantum computer is on track by 2029.
For UK businesses, the most immediately relevant announcement is the Microsoft Agent Platform and Windows Aion 1.0 Plan - a 14-billion parameter reasoning model that ships in-box as part of Windows, enabling AI agents to run locally. The strategic message from Build: AI alone will not change your business, but the system running it will.
Our take: Microsoft is betting that the next platform shift is not cloud or mobile but agentic operating systems - where AI runs continuously in the background, taking actions on behalf of users rather than waiting to be prompted. For UK businesses evaluating Microsoft 365 Copilot, Build signals that the pace of capability expansion is accelerating sharply. The question is no longer whether to adopt but whether internal governance can keep pace with what Microsoft is now enabling out of the box.
Trump signs voluntary AI frontier model review order - critics call it a missed opportunity
President Trump signed an executive order on Tuesday directing the US government to establish a voluntary framework under which AI developers can submit frontier models for government security review up to 30 days before public release. The order also creates an AI cybersecurity clearinghouse to identify and remediate software vulnerabilities at scale, and directs federal agencies to prioritise AI-enabled cybersecurity tools for critical infrastructure including hospitals, community banks, and local utilities.
The order explicitly states that nothing in it should be construed to create a mandatory licensing, pre-clearance, or permitting requirement for AI development or release - a line included to reassure the tech industry. But former Trump AI adviser Dean Ball immediately criticised it on X, saying the order was nearly identical to a draft Trump had previously rejected as too regulatory, and questioning what the intelligence community could meaningfully do in 30 days to make models safer.
For UK organisations, the order matters because it signals the direction of US AI governance: a voluntary, industry-cooperative model that prioritises national security rather than consumer protection or transparency. That approach is likely to widen regulatory divergence between the US and the EU, with the UK sitting somewhere in between.
Our take: Voluntary frameworks tend to formalise what leading companies were already doing, while providing no mechanism to catch those that do not comply. The order's most consequential element may not be the review window but the cybersecurity clearinghouse - a government-industry intelligence-sharing mechanism for AI-specific vulnerabilities that has no direct equivalent in the UK or EU yet. UK boards should watch whether the ICO or NCSC moves to establish something similar in response.
UK banks offered GPT-5.5 Cyber as Anthropic keeps Mythos restricted
OpenAI has offered nine major UK banks access to its GPT-5.5 Cyber model for security testing, stepping in after Anthropic continued to restrict access to its rival Claude Mythos. Lloyds Banking Group, HSBC and Nationwide are among those gaining access under the new offer. NatWest and Santander already had access under existing agreements.
The move follows Bank of England governor Andrew Bailey's warning last week that UK banks remained unable to access Mythos to test the security of their own systems. Former UK Chancellor George Osborne - now a senior executive at OpenAI - told the BBC that Bailey had not contacted him directly, and said his firm did not want to keep GPT-5.5 Cyber to itself. He confirmed it would not become universally available: "The key things with these tools is that they need to be in the hands of the right people."
Anthropic says it is urgently working to expand Mythos access, and believes its capabilities sit in a tier above GPT-5.5 Cyber - a claim the UK AI Security Institute's independent testing found "a similar level of performance" on the tasks it set. Anthropic initially opened Mythos to 42 companies, mostly US tech firms.
Our take: The UK banking sector is now caught between two competing access regimes for the most capable cyber AI tools, with the most powerful (Mythos) still unavailable and the alternative (GPT-5.5 Cyber) being positioned as a stopgap. For UK financial sector CISOs, this is a live procurement and risk management question today. The Bank of England's very public pressure campaign is unusual - and may accelerate Anthropic's ongoing UK expansion talks.
Nvidia unveils RTX Spark chip: Jensen Huang calls it the reinvention of the computer
Nvidia CEO Jensen Huang unveiled the RTX Spark at Computex 2026 in Taipei - a new laptop chip designed to run powerful AI agents directly on Windows PCs without requiring cloud connectivity. Huang described the announcement as the "reinvention of the computer", positioning locally-running AI agents as the next fundamental shift in personal computing.
The announcement directly echoed comments from Qualcomm CEO Cristiano Amon, who also spoke at Computex and framed 2026 as the turning point for agentic AI on personal devices. Both companies are betting that the shift from cloud-dependent AI to on-device AI agents will define the next PC upgrade cycle.
Microsoft's simultaneous Build announcement of Aion 1.0 Plan - a 14-billion parameter model shipping in-box with Windows - signals close alignment between the two companies on direction of travel. For enterprise IT teams managing Windows fleets, this means AI agents running locally on employee devices will become a default feature of the OS within the next major release cycle.
Our take: On-device AI agents shift the risk surface in a way that matters to UK businesses. When AI runs locally rather than in the cloud, it bypasses some of the data sovereignty and residency controls that compliance teams have built for cloud deployments. IT and security leaders should start thinking now about what policy governs an AI agent that has direct access to a local file system, browser, email, and calendar - with no network hop to audit.
Deloitte UK appoints its first Chief AI Officer
Deloitte UK has appointed Hayley McKelvey as its first chief AI officer, adding the role to its UK executive team. McKelvey previously served as chief AI officer for Deloitte's UK tax and legal practices and brings more than 20 years of digital transformation experience across client services and internal operations.
Her brief spans both client-facing AI deployment and internal operations - a dual mandate that reflects the growing recognition that professional services firms cannot credibly advise clients on AI transformation while running their own operations on legacy processes.
The appointment forms part of a broader series of strategic hires at Deloitte UK's executive level, encompassing technology, AI, and risk functions.
Our take: The creation of a dedicated Chief AI Officer role at Deloitte UK's top level is a signal rather than just an HR story. It tells the market that AI governance and AI strategy are now board-level concerns, not something that can be delegated to a digital transformation team. UK businesses without a clear AI owner at the executive level should take note - advisers and clients alike are getting their houses in order.
UK firms burning money on confused AI rollouts as staff are kept in the dark
Analysis published this week finds that many UK organisations are deploying AI without being able to articulate why - producing wasted spend, disengaged employees, and AI projects that quietly fail to deliver. Consultants report sitting with leadership teams where the chief executive, sales head, and marketing lead each give a different answer when asked what the company's reason for using AI actually is.
The pattern is worsening under external pressure. Accenture reportedly told staff that senior promotions would require regular AI tool use, while KPMG built a dashboard to check whether US employees hit a 75% usage target. Culture Amp research found nine in ten HR professionals expect to increase generative AI use - while a third say no one at their company actually owns AI strategy.
The public sector shows the same strain. A survey of civil servants found fewer than a third had been consulted on AI rollout, with change being done to workers rather than with them. Separately, an Amex European Business Barometer of 500 UK senior decision-makers found 92% are using AI or planning to within two years, but 71% believe long-term success requires combining AI with human insight - a tension that muddled rollout strategies make harder to resolve.
Our take: The gap between AI adoption rates and AI value creation is the defining business problem of 2026. The businesses pulling ahead are not the ones with the most AI tools - they are the ones that started with a specific business problem and worked backwards to the tool. If your leadership team cannot give a consistent answer to why you are using AI, that is a strategy problem. It cannot be solved by adding more tools or tracking usage metrics.
