Perplexity launches AI browser to challenge Google Chrome

Perplexity AI, backed by Nvidia and other major investors, has launched Comet, an AI-driven web browser designed to rival Google Chrome.

The browser uses ‘agentic AI’ that performs tasks, makes decisions, and simplifies workflows in real time, offering users an intelligent alternative to traditional search and navigation.

Comet’s assistant can compare products, summarise articles, book meetings, and handle research queries through a single interface. Initially available to subscribers of Perplexity Max at US$200 per month, Comet will gradually roll out more broadly via invite during the summer.

The launch signals Perplexity’s move into the competitive browser space, where Chrome currently dominates with a 68 per cent global market share.

The company aims to challenge not only Google’s and Microsoft’s browsers but also compete with OpenAI, which recently introduced search to ChatGPT. Unlike many AI tools, Comet stores data locally and does not train on personal information, positioning itself as a privacy-first solution.

Still, Perplexity has faced criticism for using content from major media outlets without permission. In response, it launched a publisher partnership program to address concerns and build collaborative relationships with news organisations like Forbes and Dow Jones.

Nvidia nears $4 trillion milestone as AI boom continues

Nvidia has made financial history by nearly reaching a $4 trillion market valuation, a milestone highlighting investor confidence in AI as a powerful economic force.

Shares briefly peaked at $164.42 before closing slightly lower at $162.88, just under the record threshold. The rise underscores Nvidia’s position as the leading supplier of AI chips amid soaring demand from major tech firms.

Led by CEO Jensen Huang, the company now holds a market value larger than the economies of Britain, France, or India.

Nvidia’s growth has helped lift the Nasdaq to new highs, aided in part by improved market sentiment following Donald Trump’s softened stance on tariffs.

However, trade barriers with China continue to pose risks, including export restrictions that cost Nvidia $4.5 billion in the first quarter of 2025.

Despite those challenges, Nvidia secured a major AI infrastructure deal in Saudi Arabia during Trump’s visit in May. Innovations such as the next-generation Blackwell GPUs and ‘real-time digital twins’ have helped maintain investor confidence.

The company’s stock has risen over 21% in 2025, far outpacing the Nasdaq’s 6.7% gain. Nvidia chips are also being used by the US administration as leverage in global tech diplomacy.

While competition from Chinese AI firms like DeepSeek briefly knocked $600 billion off Nvidia’s valuation, Huang views rivalry as essential to progress. With the growing demand for complex reasoning models and AI agents, Nvidia remains at the forefront.

Still, the fast pace of AI adoption raises concerns about job displacement, with firms like Ford and JPMorgan already reporting workforce impacts.

xAI unveils Grok 4 with top benchmark scores

Elon Musk’s AI company, xAI, has launched its latest flagship model, Grok 4, alongside an ultra-premium $300 monthly plan named SuperGrok Heavy.

Grok 4, which competes with OpenAI’s ChatGPT and Google’s Gemini, can handle complex queries and interpret images. It is now integrated more deeply into the social media platform X, which Musk also owns.

Despite recent controversy, including antisemitic responses generated by Grok’s official X account, xAI focused on showcasing the model’s performance.

Musk claimed Grok 4 is ‘better than PhD level’ in all academic subjects and revealed a high-performing version called Grok 4 Heavy, which uses multiple AI agents to solve problems collaboratively.

The models scored strongly on benchmark exams, including a 25.4% score for Grok 4 on Humanity’s Last Exam, outperforming major rivals. With tools enabled, Grok 4 Heavy reached 44.4%, nearly doubling OpenAI’s and Google’s results.

It also achieved a leading score of 16.2% on the ARC-AGI-2 pattern recognition test, nearly double that of Claude Opus 4.

xAI is targeting developers through its API and enterprise partnerships while teasing upcoming tools: an AI coding model in August, a multi-modal agent in September, and video generation in October.

Yet the road ahead may be rocky, as the company works to overcome trust issues and position Grok as a serious rival in the AI arms race.

Google partners with UK government on AI training

The UK government has struck a major partnership with Google Cloud aimed at modernising public services by eliminating agreing IT systems and equipping 100,000 civil servants with digital and AI skills by 2030.

Backed by DSIT, the initiative targets sectors like the NHS and local councils, seeking both operational efficiency and workforce transformation.

Replacing legacy contracts, some of which date back decades, could unlock as much as £45 billion in efficiency savings, say ministers. Google DeepMind will provide technical expertise to help departments adopt emerging AI solutions and accelerate public sector innovation.

Despite these promising aims, privacy campaigners warn that reliance on a US-based tech giant threatens national data sovereignty and may lead to long-term lock-in.

Foxglove’s Martha Dark described the deal as ‘dangerously naive’, with concerns around data access, accountability, public procurement processes and geopolitical risk.

As ministers pursue broader technological transformation, similar partnerships with Microsoft, OpenAI and Meta are underway, reflecting an industry-wide effort to bridge digital skills gaps and bring agile solutions into Whitehall.

LG’s Exaone Path 2.0 uses AI to transform genetic testing

LG AI Research has introduced Exaone Path 2.0, an upgraded AI model designed to analyse pathology images for disease diagnosis, significantly reducing the time required for genetic testing.

The new model, unveiled Wednesday, can reportedly process pathology images in under a minute—a significant shift from conventional genetic testing methods that often take more than two weeks.

According to LG, the AI system offers enhanced accuracy in detecting genetic mutations and gene expression patterns by learning from detailed image patches and full-slide pathology data.

Developed by LG AI Research, a division of the LG Group, Exaone Path 2.0 is trained on over 10,000 whole-slide images (WSIs) and multiomics pairs, enabling it to integrate structural information with molecular biology insights. The company said it has achieved a 78.4 percent accuracy rate in predicting genetic mutations.

The model has also been tailored for specific applications in oncology, including lung and colorectal cancers, where it can help clinicians identify patient groups most likely to benefit from targeted therapies.

LG AI Research is collaborating with Professor Hwang Tae-hyun and his team at Vanderbilt University Medical Centre in the US to further its application in real-world clinical settings.

Their shared goal is to develop a multimodal medical AI platform that can support precision medicine directly within clinical environments.

Hwang, a key contributor to the US government’s Cancer Moonshot program and founder of the Molecular AI Initiative at Vanderbilt, emphasised that the aim is to create AI tools usable by clinicians in active medical practice, rather than limiting innovation to the lab.

In addition to oncology, LG AI Research plans to extend its multimodal AI initiatives into transplant rejection, immunology, and diabetes.

It is also collaborating with the Jackson Laboratory to support Alzheimer’s research and working with Professor Baek Min-kyung’s team at Seoul National University on next-generation protein structure prediction.

Global cooperation and bold ideas at WSIS+20 drive digital trust and cybersecurity resilience

The WSIS+20 Leaders’ Talk on ‘Towards a safer connected world’ brought together ministers, regulators, and experts from across the globe to share concrete strategies for strengthening digital trust and cyber resilience.

Held in Geneva and moderated by Lucien Castex, the session spotlighted multistakeholder collaboration as the cornerstone of effective cybersecurity in a connected world.

Malaysia’s Minister of Communications Fahmi Fadzil opened with a firm declaration of digital sovereignty, stressing that ‘Big Tech is not bigger than our laws’. He described ASEAN’s forthcoming Kuala Lumpur declaration, a collective regional effort to promote safe and responsible use of social media.

Echoing this approach, Greece’s Dimitris Papastergiou underlined cybersecurity as a strategic national priority, detailing the implementation of the EU’s NIS2 Directive and tools to support SMEs, and reaffirming that cybersecurity is central to “democratic institutions, public safety, and social cohesion.”

India’s Anil Kumar Lahoti presented an institutional model of cyber resilience through the National Cyber Security Coordination Centre, illustrating real-time, cross-sector collaboration to contain cascading attacks.

Lithuania’s Jurate Soviene, meanwhile, emphasised the human side of cybersecurity, showcasing the “No One Is Left Behind” movement, which engages over 160 partners to help seniors build digital confidence.

She also noted the success of Lithuania’s joint anti-scam task force involving police, telecoms, banks, and regulators. “Let’s collaborate”, may be easy to say, she reflected, “but someone must take the first step.”

Participants repeatedly turned to the theme of partnership from Asia to Europe and back again. Thailand’s Trairat Viriyasirikul highlighted their ‘regulatory sandbox’ that supports public-private experimentation in health and identity sectors, including the national MobileID system.

Spain’s Matías González described the country’s Tier 1 status in the Global Cybersecurity Index and their widely respected Cybersecurity Summer Good Camp, which has trained over 20,000 students. “Security must be holistic,” he said, “combining technology, policy, and society.”

From the Internet Society, Sally Wentworth warned that no single actor can secure the internet alone. She advocated a systems approach, from standards development and encryption to civil society inclusion. “We need technologists, industry, civil society, and governments,” she said, announcing a new co-fund initiative with the Global Cyber Alliance to support underfunded cybersecurity efforts.

Lennig Pedron of Trust Valley concluded the session with practical insights from Switzerland, where over 250 innovative companies are supported through a global network of more than 400 partners. She stressed the importance of neutral platforms and flexible financing to bridge diverse stakeholder needs: “Joint pilot projects and simplified legal processes are key to real partnerships.”

Moderator Lucien Castex closed with a quote from Jules Verne, urging the audience to pair bold imagination with real-world action. Across all interventions, the session conveyed one clear message: the future of cybersecurity—and the trust that sustains it—must be built together, across sectors, borders, and communities.

WSIS+20 spotlights urgent need for global digital skills

The WSIS+20 High-Level Event in Geneva brought together global leaders to address the digital skills gap as one of the most urgent challenges of our time. As moderator Jacek Oko stated, digital technologies are rapidly reshaping work and learning worldwide, and equipping people with the necessary skills has become a matter of equity and economic resilience.

Dr Cosmas Zavazava of ITU emphasised that the real threat is not AI itself but people being displaced by others who know how to use it. ‘Workers risk losing their jobs, not because of AI, but because someone else knows how to use AI-based tools,’ he warned.

He underscored the importance of including informal workers like artisans and farmers in reskilling initiatives. He noted that 2.6 billion people remain offline while many of the 5.8 billion connected lack meaningful digital capabilities.

Costa Rica’s Vice Minister of Telecommunications, Hubert Vargas Picado shared how the country transformed into a regional tech hub by combining widespread internet access with workforce development. ‘Connectivity alone is insufficient,’ he said, advocating for cross-sectoral training systems and targeted scholarships, especially for rural youth and women.

Similarly, Celeste Drake from the ILO pointed to gendered impacts of automation, revealing that administrative roles held mainly by women are most vulnerable. She insisted that upskilling must go hand-in-hand with policies promoting decent work, inclusive social dialogue, and regional equity.

The EU’s Michele Cervone d’Urso acknowledged the bloc’s shortfall in digital specialists and described Europe’s multipronged response, including digital academies and international talent partnerships.

Georgia’s Ekaterine Imedadze shared the success of embedding media literacy in public education and training local ambassadors to support digital inclusion in villages. Meanwhile, Anna Sophie Herken of GIZ warned of ‘massive talent waste’ in the Global South, where highly educated data workers are confined to low-value roles. Herken called for more equitable participation in the global digital economy and local AI innovation.

Private sector voices echoed the need for systemic change. EY’s Gillian Hinde stressed community co-creation and inclusive learning models, noting that only 22% of women pursue AI-related courses.

She outlined EY’s efforts to support neurodiverse learners and validate informal learning through digital badges. India’s Professor Himanshu Rai added a powerful sense of urgency, declaring, ‘AI is not the future. It’s already passing us by.’ He showcased India’s success in scaling low-cost digital access, training 60 million rural citizens, and adapting platforms to local languages and user needs.

His call for ‘compassionate’ policymaking underscored the moral imperative to act inclusively and decisively.

Speakers across sectors agreed that infrastructure without skills development risks widening the digital divide. Targeted interventions, continuous monitoring, and structural reform were repeatedly highlighted as essential.

The event’s parting thought, offered by Jacek Oko, summed up the transformative mindset required: ‘Let AI teach us about AI.’ The road ahead demands urgency, innovation, and collective action to ensure digital transformation uplifts all, especially the most vulnerable.

Italy’s Piracy Shield sparks EU scrutiny over digital rights

Italy’s new anti-piracy system, Piracy Shield, has come under scrutiny from the European Commission over potential breaches of the Digital Services Act.

The tool, launched by the Italian communications regulator AGCOM, allows authorities to block suspicious websites within 30 minutes — a feature praised by sports rights holders for minimising illegal streaming losses.

However, its speed and lack of judicial oversight have raised legal concerns. Critics argue that individuals are denied the right to defend themselves before action.

A recent glitch linked to Google’s CDN disrupted access to platforms like YouTube and Google Drive, deepening public unease.

Another point of contention is Piracy Shield’s governance. SP Tech, a company owned by Lega Serie A, manages the system, which directly benefits from anti-piracy enforcement.

The Computer & Communications Industry Association was prompted to file a complaint, citing a conflict of interest and calling for greater transparency.

While AGCOM Commissioner Massimiliano Capitanio insists the tool places Italy at the forefront of the fight against illegal streaming, growing pressure from digital rights groups and EU regulators suggests a clash between national enforcement and European law.

ChatGPT quietly tests new ‘Study Together’ feature for education

A few ChatGPT users have noticed a new option called ‘Study Together’ appearing among available tools, though OpenAI has yet to confirm any official rollout. The feature seems designed to make ChatGPT a more interactive educational companion than just delivering instant answers.

Rather than offering direct solutions, the tool prompts users to think for themselves by asking questions, potentially turning ChatGPT into a digital tutor.

Some speculate the mode might eventually allow multiple users to study together in real-time, mimicking a virtual study group environment.

With the chatbot already playing a significant role in classrooms — helping teachers plan lessons or assisting students with homework — the ‘Study Together’ feature might help guide users toward deeper learning instead of enabling shortcuts.

Critics have warned that AI tools like ChatGPT risk undermining education, so it could be a strategic shift to encourage more constructive academic use.

OpenAI has not confirmed when or if the feature will launch publicly, or whether it will be limited to ChatGPT Plus users. When asked, ChatGPT only replied that nothing had been officially announced.
