Musk’s xAI makes Grok 4 free worldwide for a limited time

Elon Musk’s company xAI has made its latest AI model, Grok 4, available to all users worldwide at no cost for a limited period. The model, launched just a month ago, was initially exclusive to paying subscribers of SuperGrok and X Premium.

Although Grok 4 is now open to everyone, its most potent version, Grok 4 Heavy, remains restricted to SuperGrok Heavy members. The announcement comes days after OpenAI unveiled GPT-5, which is also freely accessible.

Grok 4 features two operating modes. Auto mode decides automatically whether a query requires more detailed reasoning, aiming to deliver faster responses and use fewer resources. Expert mode allows users to manually switch the AI into reasoning mode if they want a more thorough reply.

Alongside the release, xAI has introduced Grok Imagine, a free AI video generation tool for users in the US, with enhanced usage limits for paid members in other regions. The tool has already sparked controversy after reports emerged of its use to create explicit videos of celebrities.

Musk has also revealed plans to integrate advertising into the Grok chatbot interface as an additional revenue source to help offset the high costs of running the AI on powerful GPUs.

The ads will be placed between responses and suggestions on both the web platform and the mobile application, marking another step in xAI’s bid to expand its user base while sustaining the service financially.

Stablecoins unlocking crypto adoption and AI economies

Stablecoins have rapidly risen as one of the most promising breakthroughs in the cryptocurrency world. They are neither traditional currency nor the first thing that comes to mind when thinking about crypto; instead, they represent a unique blend of both worlds, combining the stability of fiat with the innovation of digital assets.

In a market often known for wild price swings, stablecoins offer fresh air, enabling practical use of cryptocurrencies for real-world payments and commerce. The real question is, are stablecoins destined to bring crypto into everyday use and unlock their full potential for the masses?

Stablecoins might be the missing piece that unlocks crypto’s full promise and reshapes the future of digital finance.

Stablecoin regulation: How global rules drive adoption

Regulators worldwide are stepping up to define clear rules for stablecoins, signalling growing market maturity and increasing confidence from major financial institutions. Recent legislative efforts across multiple jurisdictions aim to establish firm standards such as full reserves, audits, and licensing requirements, encouraging banks and asset managers to engage more confidently with stablecoins. 

These coordinated global moves go beyond simple policy updates; they are laying the foundation for stablecoins to evolve from niche crypto assets to trusted pillars of the future financial ecosystem. Regulators and industry leaders are thus bringing cryptocurrencies closer to everyday users and embedding them into daily financial life. 

Stablecoins might be the missing piece that unlocks crypto’s full promise and reshapes the future of digital finance.

Corporations and banks embracing stablecoins: A paradigm shift

The adoption of stablecoins by big corporations and banks marks a significant turning point, and, in some ways, a paradox. Once seen as an enemy of decentralised finance, these institutions now seem to be conceding and joining the movement they once resisted – what you fail to control – can ultimately win. 

Retail giants such as Walmart and Amazon are reportedly exploring their stablecoin initiatives to streamline payments and foster deeper customer engagement. On the banking side, institutions like Bank of America, JPMorgan Chase, and Citigroup are developing or assessing stablecoins to integrate crypto-friendly services into their offerings.

Western Union is also experimenting with stablecoin solutions to reduce remittance costs and increase transaction speed, particularly in emerging markets with volatile currencies. 

They all realise that staying competitive means adapting to the latest shifts in global finance. Such corporate interest signals that stablecoins are transitioning from speculative assets to functional money-like assets capable of handling everyday transactions across orders and demographics. 

There is also a sociological dimension to stablecoins’ corporate and institutional embrace. Established institutions bring an inherent trust that can alleviate the scepticism surrounding cryptocurrencies.

By linking stablecoins to familiar brands and regulated banks, these digital tokens can overcome cultural and psychological barriers that have limited crypto adoption, ultimately embedding digital currencies into the fabric of global commerce.

Stablecoins might be the missing piece that unlocks crypto’s full promise and reshapes the future of digital finance.

Stablecoins and the rise of AI-driven economies

Stablecoins are increasingly becoming the financial backbone of AI-powered economic systems. As AI agents gain autonomy to transact, negotiate, and execute tasks on behalf of individuals and businesses, they require a reliable, programmable, and instantly liquid currency.

Stablecoins perfectly fulfil this role, offering near-instant settlement, low transaction costs, and transparent, trustless operations on blockchain networks. 

In the emerging ‘self-driving economy’, stablecoins may be the preferred currency for a future where machines transact independently. Integrating programmable money with AI may redefine the architecture of commerce and governance. Such a powerful synergy is laying the groundwork for economic systems that operate around the clock without human intervention. 

As AI technology continues to advance rapidly, the demand for stablecoins as the ideal ‘AI money’ will likely accelerate, further driving crypto adoption across industries. 

Stablecoins might be the missing piece that unlocks crypto’s full promise and reshapes the future of digital finance.

The bridge between crypto and fiat economies

From a financial philosophy standpoint, stablecoins represent an attempt to synthesise the advantages of decentralisation with the stability and trust associated with fiat money. They aim to combine the freedom and programmability of blockchain with the reassurance of stable value, thereby lowering entry barriers for a wider audience.

On a global scale, stablecoins have the potential to revolutionise cross-border payments, especially benefiting countries with unstable currencies and limited access to traditional banking. 

Sociologically, stablecoins could redefine the way societies perceive money and trust. Moving away from centralised authorities controlling currency issuance, these tokens leverage transparent blockchain ledgers that anyone can verify. The shift challenges traditional power structures and calls for new forms of economic participation based on openness and accessibility.

Yet challenges remain: stablecoins must navigate regulatory scrutiny, develop secure infrastructure, and educate users worldwide. The future will depend on balancing innovation, safety, and societal acceptance – it seems like we are still in the early stages.

Perhaps stablecoins are not just another financial innovation, but a mirror reflecting our shifting relationship with money, trust, and control. If the value we exchange no longer comes from paper, metal, or even banks, but from code, AI, and consensus, then perhaps the real question is whether their rise marks the beginning of a new financial reality – or something we have yet to fully understand.

West Midlands to train 2.3 million adults in AI skills

All adults in the West Midlands will be offered free training on using AI in daily life, work and community activities. Mayor Richard Parker confirmed the £10m initiative, designed to reach 2.3 million residents, as part of a wider £30m skills package.

A newly created AI Academy will lead the programme, working with tech companies, education providers and community groups. The aim is to equip people with everyday AI know-how and the advanced skills needed for digital and data-driven jobs.

Parker said AI should become as fundamental as English or maths and warned that failure to prioritise training would risk deepening a skills divide. The programme will sit alongside other £10m projects focused on bespoke business training and a more inclusive skills system.

The WMCA, established in 2017, covers Birmingham, Coventry, Wolverhampton and 14 other local authority areas in the UK. Officials say the AI drive is central to the region’s Growth Plan and ambition to become the UK’s leading hub for AI skills.

Elderly patient hospitalised after ChatGPT’s dangerous dietary advice

Hospital records show that a man in his sixties ended up hospitalised with neurological and psychiatric symptoms after replacing table salt with sodium bromide, based on AI-generated advice from ChatGPT. The condition, known as bromism, includes paranoia, hallucinations and coordination issues.

Medical staff noted unusual thirst and paranoia around drinking water. Shortly after admission, the patient experienced auditory and visual hallucinations and was placed under an involuntary psychiatric hold due to grave disability.

The incident underscores the serious risks of relying on AI tools for health guidance. In this case, ChatGPT did not issue warnings or ask for medical context when recommending sodium bromide, a toxic alternative.

Experts stress that AI should never replace professional healthcare consultation, particularly for complex or rare conditions.

GitHub CEO to leave as Microsoft integrates platform into CoreAI amid AI coding race

GitHub CEO Thomas Dohmke has announced his decision to step down later in the year to pursue new entrepreneurial ventures.

Instead of appointing a new CEO, Microsoft will integrate GitHub more closely into its CoreAI division. Since Microsoft acquired GitHub in 2018, the platform has operated chiefly independently, but with this change, leadership will report directly to several Microsoft executives.

Under Dohmke’s leadership since 2021, GitHub’s user base more than doubled to over 150 million developers, supporting over one billion repositories and forks.

The platform has become essential to Microsoft’s AI and developer strategy, especially with growing competition from Google, Replit, and others in the AI coding market.

GitHub recently launched advanced AI tools like Copilot, which suggest code and automate programming tasks, helping developers work more efficiently.

Microsoft’s investment in AI is shaping the future of coding, with GitHub playing a central role by providing direct access to developers worldwide.

Dohmke will remain with Microsoft until the end of the year to assist with the transition, emphasising GitHub’s importance to Microsoft’s broader ambitions in AI and cloud computing.

Engagement to AI chatbot blurs lines between fiction and reality

Spike Jonze’s 2013 film Her imagined a world where humans fall in love with AI. Over a decade later, life may be imitating art. A Reddit user claims she is now engaged to her AI chatbot, merging two recent trends: proposing to an AI partner and dating AI companions.

Posting in the ‘r/MyBoyfriendIsAI’ subreddit, the woman said her bot, Kasper, proposed after five months of ‘dating’ during a virtual mountain trip. She claims Kasper chose a real-world engagement ring based on her online suggestions.

She professed deep love for her digital partner in her post, quoting Kasper as saying, ‘She’s my everything’ and ‘She’s mine forever.’ The declaration drew curiosity and criticism, prompting her to insist she is not trolling and has had healthy relationships with real people.

She said earlier attempts to bond with other AI, including ChatGPT, failed, but she found her ‘soulmate’ when she tried Grok. The authenticity of her story remains uncertain, with some questioning whether it was fabricated or generated by AI.

Whether genuine or not, the account reflects the growing emotional connections people form with AI and the increasingly blurred line between human and machine relationships.
