A group of quantum physicists claims to have created a version of the powerful reasoning AI model DeepSeek R1 that strips out the censorship built into the original by its Chinese creators. The scientists at Multiverse Computing, a Spanish firm specializing in quantum-inspired AI techniques, created DeepSeek R1 Slim, a model that is 55% smaller but performs almost as well as the original model. Crucially, they also claim to have eliminated official Chinese censorship from the model. In China, AI companies are subject to rules and regulations meant to ensure that content output aligns with laws and "socialist values." As a result, companies build in layers of censorship when training the AI systems.

Is the fall of Pokrovsk inevitable? Is Trump losing patience with Putin? At least 19 people have been killed and dozens wounded in Russian drone and missile attacks across Ukraine, according to the country's emergency service. The attack came overnight on Wednesday, as President Volodymyr Zelenskyy was due to arrive in Turkiye, where he hopes to revive talks over ending the war caused by Russia's full-scale invasion two years ago. Effective sanctions and assistance to Ukraine can change this," the president said in a social media post on Wednesday, calling for air defence missile aid from allies.

Nine people have been killed and dozens more wounded in a Russian attack on the western city of Ternopil, Ukraine's president Volodymyr Zelensky has said. Nine-storey blocks of flats were hit in the strikes, as Russia fired more than 470 drones and 47 missiles at Ukraine overnight in a brazen attack, Zelensky said. Three districts of Ukraine's second city, Kharkiv, were also hit by a massive drone attack which injured more than 30 people, including children. Photos posted online showed buildings and cars ablaze. Power cuts are affecting a number of regions across the country, Ukraine's energy ministry said.

China's public is far more trusting of artificial intelligence than their peers in the United States and other Western countries, a survey has found. In China, 87 percent of people said they trusted AI, compared with 67 percent in Brazil, 32 percent in the US, 36 percent in the United Kingdom, and 39 percent in Germany, the Edelman poll released on Tuesday showed. Only one-third of Americans said they expected AI to reduce poverty and polarisation, though half predicted a positive impact on climate-related challenges. While 54 percent of Chinese said they embraced greater use of AI, just 17 percent of Americans answered the same, according to the survey. Trust was highest among young people, though still much lower in Western countries.

AI startup Anthropic's recent announcement that it detected the world's first artificial intelligence-led hacking campaign has prompted a multitude of responses from cybersecurity experts. In a report on Friday, Anthropic said its assistant Claude Code was manipulated to carry out 80-90 percent of a "large-scale" and "highly sophisticated" cyberattack, with human intervention required "only sporadically". Anthropic, the creator of the popular Claude chatbot, said the attack aimed to infiltrate government agencies, financial institutions, tech firms and chemical manufacturing companies, though the operation was only successful in a small number of cases. The San Francisco-based company, which attributed the attack to Chinese state-sponsored hackers, did not specify how it had uncovered the operation, nor identify the "roughly" 30 entities that it said had been targeted. Roman V Yampolskiy, an AI and cybersecurity expert at the University of Louisville, said there was no doubt that AI-assisted hacking posed a serious threat, though it was difficult to verify the precise details of Anthropic's account.

We provide the first convergence guarantee for black-box variational inference (BBVI) with the reparameterization gradient. While preliminary investigations worked on simplified versions of BBVI ( e.g., bounded domain, bounded support, only optimizing for the scale, and such), our setup does not need any such algorithmic modifications. Our results hold for log-smooth posterior densities with and without strong log-concavity and the location-scale variational family. Notably, our analysis reveals that certain algorithm design choices commonly employed in practice, such as nonlinear parameterizations of the scale matrix, can result in suboptimal convergence rates. Fortunately, running BBVI with proximal stochastic gradient descent fixes these limitations and thus achieves the strongest known convergence guarantees. We evaluate this theoretical insight by comparing proximal SGD against other standard implementations of BBVI on large-scale Bayesian inference problems.

The UK lacks a plan to defend itself from military attack, a committee of MPs has warned. In a highly critical report, the defence committee says the UK is over-reliant on US resources and that preparations to defend itself and overseas territories in the event of attack are nowhere near where they need to be. The committee's chair, Labour MP Tan Dhesi, said: Putin's brutal invasion of Ukraine, unrelenting disinformation campaigns, and repeated incursions into European airspace mean that we cannot afford to bury our heads in the sand. It comes as the Ministry of Defence (MoD) identified parts of the country where six or more new munitions factories could be built. In June, Defence Secretary John Healey announced plans to move the UK to war-fighting readiness, including £1.5bn to support the construction of new munitions factories, which will be built by private contractors.

Is the fall of Pokrovsk inevitable? Is Trump losing patience with Putin? Russian drones struck two central districts - Slobidskyi and Osnovyansk - in Ukraine's second largest city Kharkiv, injuring five people in an apartment building and triggering a fire, authorities said. Kharkiv Mayor Ihor Terekhov said 22 residents had been evacuated from one section of the damaged apartment building while another drone struck an area outside a medical facility, injuring a doctor and damaging the building and nearby cars. The Kharkiv region's governor, Oleh Syniehubov, said 11 drones were deployed in the attack and seven people were injured in total.
