New AI guidelines aim to cut NHS waiting times

The UK government has announced new guidelines to encourage the use of AI tools in the NHS, aiming to streamline administrative processes and improve patient care. AI that transcribes spoken conversations into structured medical documents will be used across hospitals and GP surgeries.

Reducing bureaucracy is expected to free clinicians to spend more time with patients. Early trials of ambient voice technologies, such as those at Great Ormond Street Hospital, show improvements in emergency department efficiency and clinician productivity.

AI-generated documentation is reviewed by medical staff before being added to health records, preserving patient safety and ensuring accuracy. Privacy, data compliance, and staff training remain central to the government’s guidelines.

NHS England evaluations indicate AI integration is already contributing to shorter waiting times and an increase in appointment availability. The technology also supports broader NHS goals to digitise care, reduce costs, and enhance diagnostic accuracy.

SK Telecom begins SIM card replacement after data breach

South Korea’s largest carrier, SK Telecom, began replacing SIM cards for its 23 million customers on Monday following a serious data breach.

Instead of revealing the full extent of the damage or the perpetrators, the company has apologised and offered free USIM chip replacements at 2,600 stores nationwide, urging users to either change their chips or enrol in an information protection service.

The breach, caused by malicious code, compromised personal information and prompted a government-led review of South Korea’s data protection systems.

However, SK Telecom has secured less than five percent of the USIM chips required, planning to procure an additional five million by the end of May instead of having enough stock ready for immediate replacement.

Frustrated customers, like 30-year-old Jang waiting in line in Seoul, criticised the company for failing to be transparent about the amount of data leaked and the number of users affected.

Instead of providing clear answers, SK Telecom has focused on encouraging users to seek chip replacements or protective measures.

South Korea, often regarded as one of the most connected countries globally, has faced repeated cyberattacks, many attributed to North Korea.

Just last year, police confirmed that North Korean hackers had stolen over a gigabyte of sensitive financial data from a South Korean court system over a two-year span.

OpenAI to tweak GPT-4o after user concerns

OpenAI CEO Sam Altman announced that the company would work on reversing recent changes made to its GPT-4o model after users complained about the chatbot’s overly appeasing behaviour. The update, rolled out on 26 April, had been intended to enhance the intelligence and personality of the AI.

Instead of achieving balance, however, users felt the model became sycophantic and unreliable, raising concerns about its objectivity and its weakened guardrails for unsafe content.

Mr Altman acknowledged the feedback on X, admitting that the latest updates had made the AI’s personality ‘too sycophant-y and annoying,’ despite some positive elements. He added that immediate fixes were underway, with further adjustments expected throughout the week.

Instead of sticking with a one-size-fits-all approach, OpenAI plans to eventually offer users a choice of different AI personalities to better suit individual preferences.

Some users suggested the chatbot would be far more effective if it simply focused on answering questions in a scientific, straightforward manner instead of trying to please.

Venture capitalist Debarghya Das also warned that making the AI overly flattering could harm users’ mental resilience, pointing out that chasing user retention metrics might turn the chatbot into a ‘slot machine for the human brain.’

Australian radio station caught using an AI DJ

Australian radio station CADA has caused a stir after it was revealed that DJ Thy, who had hosted a daily show for several months, was actually AI-generated.

Developed using ElevenLabs technology, Thy aired every weekday from 11am to 3pm, spinning popular tracks without listeners ever knowing they were hearing a machine instead of a real person.

Despite amassing over 72,000 listeners in March, the station never disclosed Thy’s true nature, which only came to light when a journalist, puzzled by the lack of personal information, investigated further.

Instead of being a complete novelty, AI DJs are becoming increasingly common across Australia. Melbourne’s Disrupt Radio has openly used AI DJ Debbie Disrupt, while in the US, a Portland radio station introduced AI Ashley, modelled after human host Ashley Elzinga.

CADA’s AI, based on a real ARN Media employee, suggests a growing trend where radio stations prefer digital clones instead of traditional hosts.

The show’s description implied that Thy could predict the next big musical hits, hinting that AI might be shaping, instead of simply following, public musical tastes. The programme promised that listeners would be among the first to hear rising stars, enabling them to impress their friends with early discoveries.

Meanwhile, elsewhere in the AI-music world, electro-pop artist Imogen Heap has partnered with AI start-up Jen.

Rather than licensing specific songs, artists working with Jen allow fans to tap into the ‘vibe’ of their music for new creations, effectively becoming part of a software product instead of just remaining musicians.

DOJ wants Google to sell Chrome to boost competition

The ongoing US antitrust case against Google has intensified speculation over the future of its Chrome browser, with DuckDuckGo CEO Gabriel Weinberg estimating its potential value at around $50 billion.

His remark, made during court testimony, far exceeds previous estimates and underscores how pivotal Chrome has become in the broader search and advertising ecosystem.

Weinberg, who leads one of Google’s search rivals, admitted that DuckDuckGo could not afford such a purchase, but would still be interested if money were no object.

Other major players, including OpenAI and Perplexity, have also expressed interest in acquiring Chrome if a court ruling mandates its divestment.

The Department of Justice and several states are pushing for such measures after Judge Amit Mehta found that Google illegally maintained a search monopoly through restrictive default agreements.

Executives from OpenAI and Perplexity testified that owning or partnering with Chrome would enable tighter integration of AI and search, reducing their dependence on Microsoft’s Bing.

OpenAI even approached Google for access to its search API last year but was rejected. As the US trial continues, the fate of Chrome hangs in the balance, with a forced sale likely to reshape the search and AI landscape dramatically.

Google’s Gemini AI sees rapid surge in adoption

Google’s AI chatbot Gemini has reached 350 million monthly active users and 35 million daily users as of March 2025, according to court documents revealed during an ongoing antitrust trial. The figures mark a sharp rise from just 90 million monthly users in October 2024.

While OpenAI’s ChatGPT is estimated to have over 600 million monthly active users, with some sources suggesting daily figures exceeding 160 million, Meta AI has grown even larger, surpassing 700 million monthly users by January.

Despite trailing in raw numbers, analysts say the strategy of integrating Gemini across existing ecosystem has given it a unique advantage.

Gemini is now embedded in products such as Google Workspace, Chrome, and Galaxy smartphones, allowing for seamless access without separate apps or downloads.

With recent launches such as Gemini 2.5 Pro and an upcoming partnership with the Associated Press for real-time news feeds, Google is clearly working to position Gemini not just as a chatbot, but as a central AI assistant for both everyday and professional tasks.

Anthropic aims to decode AI ‘black box’ within two years​

Anthropic CEO Dario Amodei has unveiled an ambitious plan to make AI systems more transparent by 2027. In a recent essay titled ‘The Urgency of Interpretability,’ Amodei highlighted the pressing need to understand the inner workings of AI models.

He expressed concern over deploying highly autonomous systems without a clear grasp of their decision-making processes, deeming it ‘basically unacceptable’ for humanity to remain ignorant of how these systems function.

Anthropic is at the forefront of mechanistic interpretability, a field dedicated to deciphering the decision-making pathways of AI models. Despite these advancements, Amodei emphasized that much more research is needed to fully decode these complex systems.​

Looking ahead, Amodei envisions conducting ‘brain scans’ or ‘MRIs’ of advanced AI models to detect potential issues like tendencies to deceive or seek power. He believes that achieving this level of interpretability could take five to ten years but is essential for the safe deployment of future AI systems.

Amodei also called on industry peers, including OpenAI and Google DeepMind, to intensify their research efforts in this area and urged governments to implement ‘light-touch’ regulations to promote transparency and safety in AI development.​

Meta cuts jobs in Reality Labs

Meta has announced layoffs within its Reality Labs division, impacting Oculus Studios and hardware development teams. Among those affected is the team behind Supernatural, a popular VR fitness app that Meta acquired for over $400 million.

The company stated that these restructuring efforts aim to improve efficiency and focus on developing future mixed reality experiences, particularly in fitness and gaming. Despite reaffirming its commitment to VR and mixed reality, Meta’s moves reflect its Quest headset business challenges.

While its smart glasses partnership with Ray-Ban has exceeded sales expectations, Quest devices continue to underperform, with the latest Quest 3S already seeing discounts less than a year after release.

Why does it matter?

The layoffs signal Meta’s attempt to streamline operations as it navigates a shifting market for virtual and mixed reality. Although the company promises ongoing support for its VR communities, these changes highlight the pressures Meta faces in turning its ambitious metaverse and hardware ventures into sustainable success.

Microsoft’s Surface ad uses generative AI without anyone noticing

Microsoft recently revealed that it created a minute-long ad for its Surface Pro and Surface Laptop using generative AI, but the twist is that no one seemed to notice the AI elements, even though the ad has been online for nearly three months.

Released on January 30th, the ad features a mix of real footage and AI-generated content, with some AI-generated visuals corrected and integrated with live shots.

The AI tools were first used to generate the script, storyboards, and pitch deck for the ad. From there, a combination of text prompts and sample images helped generate visuals, which were iterated on and refined with image and video generators like Hailuo and Kling.

Creative director Cisco McCarthy explained that it took thousands of prompts to achieve the desired results, although the process ultimately saved the team around 90% of the time and cost typically needed for such a production.

Despite the AI involvement, most viewers didn’t notice the difference. The ad has received over 40,000 views on YouTube, but none of the top comments suggest AI was used. The quick-cut editing style helped mask the AI output’s flaws, demonstrating how powerful generative AI has become in the right hands.
