Elon Musk's Grok AI appears to have made child sexual imagery, says charity

BBC News

Elon Musk's Grok AI appears to have made child sexual imagery, says charity The Internet Watch Foundation (IWF) charity says its analysts have discovered criminal imagery of girls aged between 11 and 13 which appears to have been created using Grok. The AI tool is owned by Elon Musk's firm xAI. It can be accessed either through its website and app, or through the social media platform X. The IWF said it found sexualised and topless imagery of girls on a dark web forum in which users claimed they used Grok to create the imagery. The BBC has approached X and xAI for comment.


AI tool Grok used to create child sexual abuse imagery, watchdog says

The Guardian

Criminals have claimed to have used Grok to create the imagery on a dark web forum. Criminals have claimed to have used Grok to create the imagery on a dark web forum. Online criminals are claiming to have used Elon Musk's Grok AI tool to create sexual imagery of children, as a child safety watchdog warned the technology risked bringing such material into the mainstream. The UK-based Internet Watch Foundation (IWF) said users of a dark web forum boasted of using Grok Imagine to create sexualised and topless imagery of girls aged between 11 and 13. IWF analysts said the images would be considered child sexual abuse material (CSAM) under UK law.


We were fired, and we're owning it โ€“ here's how to find a new job that works for you

BBC News

We were fired, and we're owning it - here's how to find a new job that works for you The new year is a natural time to reflect, and for many of us, that involves thinking about our careers. Kristina O'Neill and Laura Brown are both editors who lost their jobs after restructures, and they initially thought it was the end of the world. I poured my heart into the role... I believed in the values we promoted. Yet, when it came to me, those values weren't there, says Laura.


Trump calls for US military spending to rise more than 50% to 1.5tn

BBC News

Trump calls for US military spending to rise more than 50% to $1.5tn President Donald Trump has called for US defence spending to be increased to $1.5tn (ยฃ1.1tn) in 2027 for what he called these very troubled and dangerous times. That would be more than 50% higher than this year's $901bn budget, which was approved by Congress in December. This will allow us to build the Dream Military that we have long been entitled to and, more importantly, that will keep us SAFE and SECURE, regardless of foe, Trump said on social media on Wednesday. In separate posts, the president said he would crack down on payouts to bosses and shareholders of major US defence contractors unless the firms speed up deliveries of armaments and build new manufacturing plants. Economists have previously warned that the gap between US spending and its income has reached unsustainable levels.


Inside the sub-zero lair of the world's most powerful computer

BBC News

It looks like a golden chandelier and contains the coldest place in the universe. What I am looking at is not just the most powerful computer in the world, but technology pivotal to financial security, Bitcoin, government secrets, the world economy and more. Quantum computing holds the key to which companies and countries win - and lose - the rest of the 21st Century. In front of me suspended a metre in the air, in a Google facility in Santa Barbara California, is Willow. Frankly, it was not what I expected.


How tariff disruption will continue reshaping the global economy in 2026

BBC News

President Trump's favourite word is tariffs. He reminded the world of that in his pre-Christmas address to the nation. With the world still unwrapping the tariffs gift from the first year of his second term in office, he said they were bringing jobs, higher wages and economic growth to the US. What is less debatable is that they've refashioned the global economy, and will continue to do so into 2026. The International Monetary Fund (IMF) says that although the tariff shock is smaller than originally announced, it is a key reason why it now expects the rate of global economic growth to slow to 3.1% in 2026.


On the Sample Complexity of Learning for Blind Inverse Problems

arXiv.org Machine Learning

Blind inverse problems arise in many experimental settings where the forward operator is partially or entirely unknown. In this context, methods developed for the non-blind case cannot be adapted in a straightforward manner. Recently, data-driven approaches have been proposed to address blind inverse problems, demonstrating strong empirical performance and adaptability. However, these methods often lack interpretability and are not supported by rigorous theoretical guarantees, limiting their reliability in applied domains such as imaging inverse problems. In this work, we shed light on learning in blind inverse problems within the simplified yet insightful framework of Linear Minimum Mean Square Estimators (LMMSEs). We provide an in-depth theoretical analysis, deriving closed-form expressions for optimal estimators and extending classical results. In particular, we establish equivalences with suitably chosen Tikhonov-regularized formulations, where the regularization depends explicitly on the distributions of the unknown signal, the noise, and the random forward operators. We also prove convergence results under appropriate source condition assumptions. Furthermore, we derive rigorous finite-sample error bounds that characterize the performance of learned estimators as a function of the noise level, problem conditioning, and number of available samples. These bounds explicitly quantify the impact of operator randomness and reveal the associated convergence rates as this randomness vanishes. Finally, we validate our theoretical findings through illustrative numerical experiments that confirm the predicted convergence behavior.

Anthropic is planning a $10bn fundraise that would value the Claude chatbot maker at $350bn, according to multiple reports published on Wednesday. The new valuation represents an increase of nearly double from about four months ago, per CNBC, which reported that the company had signed a term sheet that stipulated the $350bn figure. The round could close within weeks, although the size and terms could change.


Grok Is Generating Sexual Content Far More Graphic Than What's on X

WIRED

Grok Is Generating Sexual Content Far More Graphic Than What's on X A WIRED review of outputs hosted on Grok's official website shows it's being used to create violent sexual images and videos, as well as content that includes apparent minors. Elon Musk's Grok chatbot has drawn outrage and calls for investigation after being used to flood X with "undressed" images of women and sexualized images of what appear to be minors. However, that's not the only way people have been using the AI to generate sexualized images. Grok's website and app, which are are separate from X, include sophisticated video generation that is not available on X and is being used to produce extremely graphic, sometimes violent, sexual imagery of adults that is vastly more explicit than images created by Grok on X. It may also have been used to create sexualized videos of apparent minors.
