This week, UK prime minister Rishi Sunak is hosting a group of 100 representatives from the worlds of business and politics to discuss the potential and pitfalls of artificial intelligence. The AI Safety Summit, held at Bletchley Park, UK, begins on 1 November and aims to come up with a set of global principles with which to develop and deploy "frontier AI models" – the terminology favoured by Sunak and key figures in the AI industry for powerful models that don't yet exist, but may be built very soon. While the Bletchley Park event is the focal point, there is a wider week of fringe events being held in the UK, alongside a raft of UK government announcements on AI. Here are the latest developments. The global community has decided that the week of the UK summit is a ripe time to announce their own AI developments.

The executive order comes just days before Harris is expected to promote the United States' vision for AI regulation at Britain's AI Summit, a two-day event that will gather leaders from around the world to talk about how to respond to the most risky applications of the technology. The executive order signals that the Biden administration is taking a different approach than the United Kingdom, which to date has signaled a light-touch posture toward AI companies and is focusing its summit on long-term threats of AI, including the possibility that the technology overpowers humans.

Some of Britain's biggest retailers, including Tesco, John Lewis and Sainsbury's, have been urged to pull out of a new policing strategy amid warnings it risks wrongly criminalising people of colour, women and LGBTQ people. A coalition of 14 human rights groups has written to the main retailers – also including Marks & Spencer, the Co-op, Next, Boots and Primark – saying that their participation in a new government-backed scheme that relies heavily on facial recognition technology to combat shoplifting will "amplify existing inequalities in the criminal justice system". The letter, from Liberty, Amnesty International and Big Brother Watch, among others, questions the unchecked rollout of a technology that has provoked fierce criticism over its impact on privacy and human rights at a time when the European Union is seeking to ban the technology in public spaces through proposed legislation. "Facial recognition technology notoriously misidentifies people of colour, women and LGBTQ people, meaning that already marginalised groups are more likely to be subject to an invasive stop by police, or at increased risk of physical surveillance, monitoring and harassment by workers in your stores," the letter states.Its authors also express dismay that the move will "reverse steps" that big retailers introduced during the Black Lives Matter movement, including high-profile commitments to be champions of diversity, equality and inclusion. Meanwhile, concerns over the broadening use of facial recognition technology have further intensified after the emergence of details of a police watchlist used to justify the contentious decision to use biometric surveillance at July's Formula One British Grand Prix at Silverstone.

Earlier this month, a woman in San Francisco was hit by a car while crossing the street. Had the story ended there, it would have been just another one of the small tragedies that occur on America's roads, where roughly 100 people die every day. She was hit again, this time by a robotaxi from the start-up Cruise. The car braked, coming to a stop with her pinned underneath. Then it started driving again, dragging the woman along with it for an agonizing 20 more feet.

Amazon's virtual shelves already feature books written by artificial intelligence. One startup believes that even titles written by humans would benefit from some AI, in the form of an accompanying chatbot primed to talk about a book's contents. YouAI, a startup that offers tools for building AI apps, recently developed an app it calls Book AI, which promises to "turn any book into an AI." It spins up a chatbot that knows everything about the book and can talk about it endlessly--like a bespectacled Terminator that just dropped in on your book club meeting. Dmitry Shapiro, YouAI's CEO, says he's talking with a number of publishers large and small about creating chatbots to accompany new releases.

Prof Carissa Veliz, associate professor in philosophy, Institute of Ethics in AI, at the University of Oxford, said unlike the EU the UK had so far been "notoriously averse to regulating AI, so it is interesting for Sunak to say that the UK is particularly well-suited to lead the efforts of ensuring the safety of AI".

A vulnerability in Open AI's ChatGPT – now fixed – could have been used by malicious actors Researchers manipulated ChatGPT and five other commercial AI tools to create malicious code that could leak sensitive information from online databases, delete critical data or disrupt database cloud services in a first-of-its-kind demonstration. The work has already led the companies responsible for some of the AI tools – including Baidu and OpenAI – to implement changes to prevent malicious users from taking advantage of the vulnerabilities. "It's the very first study to demonstrate that vulnerabilities of large language models in general can be exploited as an attack path to online commercial applications," says Xutan Peng, who co-led the study while at the University of Sheffield in the UK. Peng and his colleagues looked at six AI services that can translate human questions into the SQL programming language, which is commonly used to query computer databases. "Text-to-SQL" systems that rely on AI have become increasingly popular – even standalone AI chatbots, such as OpenAI's ChatGPT, can generate SQL code that can be plugged into such databases.

The spread of misinformation is a massive problem online, and generative AI is only helping boost the creation of inauthentic or real-but-repurposed media. Even in the pre-generative-AI era, an image surfaced through a quick Google search might have been used out of context or attached to a less-than-reliable website. Google believes it has at least one solution for this problem. In Google image search results, users will start seeing an information box called "About this image." It rolls out today in the US (and initially only in English).

The United States state of California has suspended testing of Cruise self-driving cars developed by General Motors (GM), citing safety concerns after a series of accidents and mishaps. California's Department of Motor Vehicles (DMV) announced on Tuesday that it had suspended the deployment of GM self-driving vehicles and driverless testing permits, the latest regulatory agency to express concerns over their safety. "When there is an unreasonable risk to public safety, the DMV can immediately suspend or revoke permits," the department said in response to an inquiry from the news outlet AFP. Self-driving cars have been met with mixed reactions from the public, some of whom see them as an exciting technological development while others view them as a nuisance or a hazard. The suspension follows a series of accidents involving Cruise vehicles and marks a serious setback for GM's efforts to break into the autonomous vehicle industry.

Microsoft on Tuesday reported strong sales in its latest quarter, showing that its corporate customers have been shaking off jitters about spending heavily in the uncertain economy. The results also showed early signs that the company's investments in generative artificial intelligence were beginning to bolster sales, most notably reversing what had been slowing growth of the company's important cloud computing product. The company had $56.5 billion in sales in the three months that ended in September, up 13 percent from a year earlier. Profit hit $22.3 billion, up 27 percent. The results beat analyst expectations and Microsoft's own estimates.
