Welcome back to In the Loop, new twice-weekly newsletter about AI. If you're reading this in your browser, why not subscribe to have the next one delivered straight to your inbox? In the past few weeks, many tech leaders have made bold predictions about what AI will achieve in 2026, from mastering the field of biology to surpassing human intelligence outright . But in 2026's first week, the most visible use of AI has been X users employing Grok to digitally disrobe women. Elon Musk's platform X has been flooded with nonconsensual AI-created images, requested by users, of unclothed or scantily-clad women, men and children, sometimes in sexual positions.

Elon Musk's Grok AI image editing limited to paid X users after deepfakes Elon Musk's platform X has limited image editing with its AI tool Grok to paying users, after it came under fire for allowing people to make sexualised deepfakes. There has been a significant backlash after the chatbot honoured requests from users to digitally alter images of other people by undressing them without their consent. But Grok is now telling people asking it to make such material that only paid subscribers would be able to do so - meaning their name and payment information must be on file. The BBC has approached X for comment. Those who do not subscribe can still use Grok to edit images on its separate app and website.

Fujitsu's physical AI system, which allows robots to move autonomously and in coordination with one another, is showcased at the CES tech show in Las Vegas on Wednesday. The robots are made by external manufacturers. LAS VEGAS - Fujitsu showed off a foundational technology that uses artificial intelligence to develop programs for software defined vehicles (SDV), at the CES tech show in Las Vegas on Wednesday. The Japanese company's technology helps automakers and other customers design software for SDVs, which can upgrade features by updating programs but require a lot of costs and labor to develop. Fujitsu also showcased its digital twin technology, reproducing the city of Las Vegas in virtual space and showing how traffic congestion there can be eased by analyzing data on the movements of people and vehicles.

Ofcom urged to use'banning' powers over X AI deepfakes The government has urged the regulator Ofcom to use all its powers - up to and including an effective ban - against X over concerns about unlawful AI images created on the site. Ofcom's powers include the ability to obtain a court order to prevent third parties from helping the Elon Musk-owned platform from raising money or from being accessed in the UK. This follows an ongoing backlash against the use of X's AI Grok to digitally remove clothing from images of people. The possibility there could be sexualised images of children raised very specific concerns in government. Addressing concerns over sexualised images of adults and children produced by Grok, Prime Minister Sir Keir Starmer said: This is disgraceful.

A Multinomial Logit (MNL) model is composed of a finite universe of items $[n]=\{1,..., n\}$, each assigned a positive weight. A query specifies an admissible subset -- called a slate -- and the model chooses one item from that slate with probability proportional to its weight. This query model is also known as the Plackett-Luce model or conditional sampling oracle in the literature. Although MNLs have been studied extensively, a basic computational question remains open: given query access to slates, how efficiently can we learn weights so that, for every slate, the induced choice distribution is within total variation distance $\varepsilon$ of the ground truth? This question is central to MNL learning and has direct implications for modern recommender system interfaces. We provide two algorithms for this task, one with adaptive queries and one with non-adaptive queries. Each algorithm outputs an MNL $M'$ that induces, for each slate $S$, a distribution $M'_S$ on $S$ that is within $\varepsilon$ total variation distance of the true distribution. Our adaptive algorithm makes $O\left(\frac{n}{\varepsilon^{3}}\log n\right)$ queries, while our non-adaptive algorithm makes $O\left(\frac{n^{2}}{\varepsilon^{3}}\log n \log\frac{n}{\varepsilon}\right)$ queries. Both algorithms query only slates of size two and run in time proportional to their query complexity. We complement these upper bounds with lower bounds of $Ω\left(\frac{n}{\varepsilon^{2}}\log n\right)$ for adaptive queries and $Ω\left(\frac{n^{2}}{\varepsilon^{2}}\log n\right)$ for non-adaptive queries, thus proving that our adaptive algorithm is optimal in its dependence on the support size $n$, while the non-adaptive one is tight within a $\log n$ factor.

The pivot doesn't look out of place at CES, where Chinese electronics companies are increasingly applying their manufacturing prowess to new industries. If you've never been to Shenzhen, China's electronics capital, the annual CES trade show in Las Vegas is the next best thing. I'm reporting this week from the sprawling event, surrounded by fancy, strange, and often unnecessary gadgets, and despite my sore legs, I've barely scratched the surface. There are at least 900 Chinese tech companies attending CES this year, almost a quarter of the total exhibitors, according to an analysis of the conference's exhibitor directory. I even saw two Chinese humanoid robots at different booths dancing to the same viral Chinese rap song five minutes apart.
