Elon Musk Unveils Grok 4: xAI's Smartest AI Yet to Rival ChatGPT and Gemini
Grok 4 was tested on a challenging benchmark called Humanity's Last Exam, which includes more than 2,500 questions across science, math, and language. The AI scored 25.4% without tools and an improved 44.4% when using advanced tool support. It also outperformed some rivals in visual reasoning, securing 16.2% on the ARC-AGI-2 test—beating Claude Opus 4.
For users looking to try Grok 4, the standard monthly subscription is priced at $30. A premium version called SuperGrok Heavy, offering early access to experimental features and multi-agent support, is available for $300 per month. The latest version also includes five new voice options for interactive responses.
Grok 4's core capabilities include writing, debugging, and explaining code. It also introduces DeepSearch—a feature that lets users get real-time information during chats without switching tabs. The platform supports not just text, but also image and video generation, aiming to rival OpenAI's GPT-4o and Google's Gemini 2.5 Pro.
The update follows a recent controversy, where xAI had to pull down Grok 3-generated posts containing antisemitic content. The issue triggered public criticism and a brief suspension, prompting the company to improve safeguards in the new version.
Musk says Grok 4 was built on xAI's powerful Colossus supercomputer to deliver faster, smarter responses across a range of applications—from daily tasks to software development.

AI is killing the Web. Can anything save it?
AROUND the beginning of last year, Matthew Prince started receiving worried calls from the chief executives of large media companies. They told Prince, whose firm, Cloudflare, provides security infrastructure to about a fifth of the Web, that their businesses faced a grave new online threat. 'I said, 'What, is it the North Koreans?',' he recalls. 'And they said, 'No. It's AI'.' Those executives had spotted the early signs of a trend that has since become clear: artificial intelligence is transforming the way that people navigate the Web. As users pose their queries to chatbots rather than conventional search engines, they are given answers, rather than links to follow. The result is that 'content' publishers, from news providers and online forums to reference sites such as Wikipedia, are seeing alarming drops in their traffic. As AI changes how people browse, it is altering the economic bargain at the heart of the Internet. Human traffic has long been monetised using online advertising; now that traffic is drying up. Content producers are urgently trying to find new ways to make AI companies pay them for information. If they cannot, the open Web may evolve into something very different. Since the launch of ChatGPT in late 2022, people have embraced a new way to seek information online. OpenAI, maker of ChatGPT, says that around 800 million people use the chatbot. It is the most popular download on the iPhone App Store. Apple said that conventional searches in its Safari Web browser had fallen for the first time in April, as people posed their questions to AI instead. OpenAI is soon expected to launch a browser of its own. Its rise is so dramatic that a Hollywood adaptation is in the works. As OpenAI and other upstarts have soared, Google, which has about 90 per cent of the conventional search market in America, has added AI features to its own search engine in a bid to keep up. Last year, it began preceding some search results with AI-generated 'overviews', which have since become ubiquitous. In May, it launched 'AI mode', a chatbot-like version of its search engine. The company promises that, with AI, users can 'let Google do the googling for you'. Yet as Google does the googling, humans no longer visit the websites from which the information is gleaned. Similarweb, which measures traffic to more than 100 million Web domains, estimates that worldwide search traffic (by humans) fell by about 15 per cent in the year to June. Although some categories, such as hobbyists' sites, are doing fine, others have been hit hard. Many of the most affected are just the kind that might have commonly answered search queries. Science and education sites have lost 10 per cent of their visitors. Reference sites have lost 15 per cent. Health sites have lost 31 per cent. BT in your inbox Start and end each day with the latest news stories and analyses delivered straight to your inbox. Sign Up Sign Up For companies that sell advertising or subscriptions, lost visitors means lost revenue. 'We had a very positive relationship with Google for a long time... They broke the deal,' says Neil Vogel, head of Dotdash Meredith, which owns titles such as People and Food & Wine. Three years ago, its sites got more than 60 per cent of their traffic from Google. Now the figure is in the mid-30s. 'They are stealing our content to compete with us,' adds Vogel. Google has insisted that its use of others' content is fair. But since it launched its AI overviews, the share of news-related searches resulting in no onward clicks has risen from 56 per cent to 69 per cent, estimates Similarweb. In other words, seven in 10 people get their answer without visiting the page that supplied it. 'The nature of the Internet has completely changed,' says Prashanth Chandrasekar, CEO of Stack Overflow, best known as an online forum for coders. 'AI is basically choking off traffic to most content sites,' he notes. With fewer visitors, Stack Overflow is seeing fewer questions posted on its message boards. Wikipedia, also powered by enthusiasts, warns that AI-generated summaries without attribution 'block pathways for people to access…and contribute to' the site. To keep the traffic and the money coming, many big content producers have negotiated licensing deals with AI companies, backed up by legal threats: what Robert Thomson, CEO of News Corp, has dubbed 'wooing and suing'. His company, which owns The Wall Street Journal and the New York Post, among other titles, has struck a deal with OpenAI. Two of its subsidiaries are suing Perplexity, another AI answer engine. The New York Times has done a deal with Amazon while suing OpenAI. Plenty of other transactions and lawsuits are going on. (The Economist's parent company has not taken a public position on whether it will license our work.) Yet this approach has limits. For one thing, judges so far seem minded to side with AI companies: last month two separate copyright cases in California went in favour of their defendants, Meta and Anthropic, both of which argued that training their models on others' content amounted to fair use. US President Donald Trump seems to accept Silicon Valley's argument that it must be allowed to get on with developing the technology of the future before China can. He has appointed tech boosters as advisers on AI, and sacked the head of the US Copyright Office soon after she argued that training AI on copyrighted material was not always legal. AI companies are more willing to pay for continuing access to information than training data. But the deals done so far are hardly stellar. Reddit, an online forum, has licensed its user-generated content to Google for a reported US$60 million a year. Yet its market value fell by more than half – over US$20 billion – after it reported slower user-growth than expected in February, owing to wobbles in search traffic. (Growth has since picked up and Reddit's share price has recovered some lost ground.) The bigger problem, however, is that most of the Internet's hundreds of millions of domains are too small to either woo or sue the tech giants. Their content may be collectively essential to AI firms, but each site is individually dispensable. Even if they could join forces to bargain collectively, antitrust law would forbid it. They could block AI crawlers, and some do. But that means no search visibility at all. Software providers may be able to help. All of Cloudflare's new customers will now be asked if they want to allow AI companies' bots to scrape their site, and for what purpose. Cloudflare's scale gives it a better chance than most of enabling something like a collective response by content sites that want to force AI firms to cough up. It is testing a pay-as-you-crawl system that would let sites charge bots an entry fee. 'We have to set the rules of the road,' says Prince, who adds that his preferred outcome is 'a world where humans get content for free, and bots pay a tonne for it'. An alternative is offered by TollBit, which bills itself as a paywall for bots. It allows content sites to charge AI crawlers varying rates: for instance, a magazine could charge more for new stories than old ones. In the first quarter of this year TollBit processed 15 million micro-transactions of this sort, for 2,000 content producers including the Associated Press and Newsweek. Toshit Panigrahi, its CEO, points out that whereas traditional search engines incentivise samey content – 'What time does the Super Bowl start?', for example – charging for access incentivises uniqueness. One of TollBit's highest per-crawl rates is charged by a local newspaper. Another model is being put forward by ProRata, a startup led by Bill Gross, a pioneer in the 1990s of the pay-as-you-click online ads that have powered much of the Web ever since. He proposes that money from ads placed alongside AI-generated answers should be redistributed to sites in proportion to how much their content contributed to the answer. ProRata has its own answer engine, which shares ad revenue with its 500-plus partners, which include the Financial Times and The Atlantic. It is currently more of an exemplar than a serious threat to Google. Gross says his main aim is to 'show a fair business model that other people eventually copy'. Meanwhile, content producers are rethinking their business models. 'The future of the Internet is not all about traffic,' says Chandrasekar, who has built up Stack Overflow's private, enterprise-oriented subscription product, Stack Internal. News publishers are planning for 'Google zero', deploying newsletters and apps to reach customers who no longer come to them via search, and moving their content behind paywalls or to live events. Audio and video are proving legally and technically harder for AI engines to summarise than text. The site to which answer engines refer search traffic most often, by far, is YouTube, according to Similarweb. Not everyone thinks the Web is in decline – on the contrary, it is in 'an incredibly expansionary moment', argues Robby Stein of Google. As AI makes it easier to create content, the number of sites is growing: Google's bots report that the Web has expanded by 45 per cent in the past two years. AI search lets people ask questions in new ways – for instance, taking a photo of their bookshelf and asking for recommendations on what to read next – which could increase traffic. With AI queries, more sites than ever are being 'read', even if not with human eyes. An answer engine may scan hundreds of pages to deliver an answer, drawing on a more diverse range of sources than human readers would. As for the idea that Google is disseminating less human traffic than before, Stein says the company has not noticed a dramatic decline in the number of outbound clicks, though it declines to make the number public. There are other reasons besides AI why people may be visiting sites less. Maybe they are scrolling social media. Maybe they are listening to podcasts. The death of the Web has been predicted before – at the hands of social networks, then smartphone apps –and not come to pass. But AI may pose the biggest threat to it yet. If the Web is to continue in something close to its current form, sites will have to find new ways to get paid for content. 'There's no question that people prefer AI search,' says Gross. 'And to make the Internet survive, to make democracy survive, to make content creators survive, AI search has to share revenue with creators.' ©2025 The Economist Newspaper Limited.

Oracle to invest $3 billion in AI, cloud expansion in Germany, Netherlands
Oracle will invest $3 billion over the next five years in artificial intelligence and cloud infrastructure in Germany and the Netherlands to meet upbeat demand, the company said in separate statements on Tuesday. The cloud service provider plans to allocate $2 billion to Germany and $1 billion to the Netherlands. Major technology firms have poured tens of billions of dollars into developing AI infrastructure following the success of OpenAI's ChatGPT. Oracle, whose cloud offerings support companies in building AI infrastructure, has seen its shares surge about 38 per cent so far this year. In June, the company raised its annual revenue forecast, driven by strong demand for its AI-related cloud services.

Tesla to sell Model Y cars in India, starting at $89k
Find out what's new on ST website and app. People are seen outside the Tesla showroom ahead of its opening in Mumbai on July 15. MUMBAI - Tech billionaire Elon Musk's Tesla has priced its Model Y at about US$69,770 (S$89,450) in India, the highest among major markets, its website showed, as the electric carmaker geared up to open its first showroom in Mumbai on July 15. With delivery estimated to start from the third quarter, Tesla will drive on to India's busy roads, targeting a niche premium EV segment that accounts for just 4 per cent of overall sales in the world's third-largest car market. It will compete mainly with German luxury giants such as BMW and Mercedes-Benz, rather than domestic mass-market EV players such as Tata Motors and Mahindra. Tesla's Model Y rear-wheel drive will set back buyers 6 million rupees (S$89,000), while its Model Y long-range rear-wheel drive costs 6.8 million rupees. That compares with a starting price from US$44,990 in the United States, 263,500 yuan (S$47,100) in China, and €45,970 (S$68,800) in Germany. Grappling with excess capacity in global factories and declining sales, Tesla has adopted a strategy of selling imported vehicles in India, despite duties and levies running into roughly 70 per cent. On July 15, police guarded Tesla's first showroom in India as media crowded outside the office complex where it is located and the chief minister of the western state of Maharashtra, home to the Indian commercial capital, arrived for the launch.

Access was tightly regulated, with no sign of fans or onlookers nearby. Tesla's website showed the Model Y available for registration in Mumbai at an on-road price of 6.1 million rupees, with a booking deposit of 22,220 rupees. The firm's Full Self-Driving (FSD) capability is on offer at an additional cost of 600,000 rupees, with future updates promised to enable operation with minimal driver intervention. While the current features require active driver supervision and are not fully autonomous, Tesla says the system will evolve through over-the-air software updates. REUTERS
