A new research paper introduces a "channel-transition" framework to explain why large language models struggle to maintain context and instructions over extended multi-turn conversations. The study proposes the Goal Accessibility Ratio (GAR) as a metric to quantify the degradation of attention to key instructions. Researchers found that while attention to instructions may close, relevant information can persist in residual representations, leading to varied failure modes across different model architectures.

Researchers from Bosch and Carnegie Mellon University have developed a new AI system called Humanoid Transformer with Touch Dreaming (HTD) to enhance the dexterity of humanoid robots. This system integrates tactile sensing, multi-view vision, and proprioception to enable robots to predict the outcomes of touch and force, allowing for more precise object manipulation. In tests, HTD significantly improved task success rates by over 90% across various real-world manipulation tasks, addressing a key challenge in humanoid robotics. AI

An audit in Ontario, Canada, has revealed significant inaccuracies in AI medical scribes recommended by the provincial government. These tools, intended to help doctors summarize patient interactions, were found to generate incorrect, incomplete, and hallucinated information. The audit tested 20 vendors, with all showing issues, including fabricated referrals, misidentified medications, and missed mental health details, raising concerns about potential harm to patient care.

Researchers have developed EditLens, a new method to quantify the extent to which AI has been used to edit text. This approach aims to provide a more nuanced understanding of AI's role in content creation and modification. The findings are detailed in a paper published on arXiv. AI

Berryville IML has released a new report detailing methods for measuring security in machine learning systems, drawing parallels to established software security practices. The report, available for free under a creative commons license, aims to provide actionable insights for applied ML security. AI

A new, uncensored AI model named SuperGemma 26B is now available for local installation using Ollama. Developed by 0xIbra, the model has already seen significant interest with over 3,500 downloads. Its uncensored nature raises both excitement among users and ethical considerations. AI

New Brunswick's premier is considering a ban on social media for young people and a review of AI chatbots in the anglophone sector's draft curriculum. These proposals stem from concerns about the impact of social media and AI on youth. The province is exploring these measures to address potential risks associated with these technologies. AI

A Nevada electric company plans to divert power from 50,000 residents to supply data centers. This decision affects multiple towns, which have been told to find alternative power sources. The move highlights the growing demand for energy to support data center infrastructure, particularly for AI. AI

The Trump administration is asserting its authority to prevent individuals deemed experts in social media content moderation from entering the United States. This legal battle involves a lawsuit where the administration is defending its right to deny entry to these experts, with a US District Court Judge hearing arguments on the matter. AI

Frontier AI models are showing a rapid increase in their ability to handle complex tasks, with their reliability doubling every 4.7 months, a rate that has accelerated since late 2024. Recent models like Claude Mythos Preview and GPT-5.5 are outperforming these trends, though their exact capabilities are still being measured due to near-perfect success rates on current benchmarks. This rapid progress challenges existing testing methodologies, as models are pushing the limits of token capacity and agent scaffolding, making it difficult to accurately assess their performance and potential deterioration at scale.

Mind Robotics, a spinoff from Rivian, has secured $400 million in new funding, bringing its total capital raised to over $1 billion. This significant investment validates the company's early backers and signals strong confidence in its future. The substantial financial backing is expected to accelerate Mind Robotics' development and market presence. AI

Cerebras Systems has announced a new wafer-scale engine designed to accelerate AI model training and inference. The company claims this new hardware significantly reduces the time required for processing tokens, a key metric in large language model performance. This advancement aims to address the growing computational demands of complex AI workloads. AI

Microsoft Research has unveiled GridSFM, a compact foundation model designed to optimize power grid efficiency. This model can predict optimal AC power flow in milliseconds, aiding operators in managing grid congestion, stability, and overall system health for cost savings. Separately, Andrew Ng refutes the notion of an imminent "jobpocalypse" due to AI, asserting that AI will transform rather than replace jobs, necessitating adaptation over excessive fear. AI

Meta has decided not to open-source its Muse Spark AI model, citing safety concerns related to its potential for misuse in chemical and biological applications. This decision represents a strategic shift for Meta, moving away from a principle of open-sourcing towards a more selective approach based on deployment safety. The model is slated for integration into Meta's own platforms and devices, such as its augmented reality glasses. AI

Fervo Energy's initial public offering experienced a significant 33% increase on its first day of trading. This surge in valuation, which propelled the company's worth beyond $10 billion, is largely attributed to the escalating demand for AI data centers. The company's focus on geothermal energy solutions is seen as a key factor in meeting this growing need for sustainable power in the AI infrastructure sector. AI

Elon Musk's xAI is reportedly operating 46 natural gas turbines at its Mississippi data center without permits, potentially violating the Clean Air Act. The state of Mississippi considers the turbines "mobile" because they are on trailers, allowing them to operate for up to a year without permits, despite concerns about air quality and public health. The NAACP has filed a lawsuit, arguing that these turbines should be classified as stationary and subject to regulations, and is seeking an injunction against xAI's operations. AI

SoftBank's investment in OpenAI is reportedly boosting its quarterly profits, with analysts estimating its stake to be worth around $80 billion. However, concerns are rising about SoftBank's increasing debt to fund its AI strategy and the concentration of risk in a single company. Despite these worries, SoftBank's stock has seen significant gains, indicating investor confidence for the time being. AI

Berryville Infrastructure & Machine Learning (BIML) has published a new study highlighting a lack of security metrics for AI systems. The research indicates that current security practices are insufficient to address the unique risks posed by artificial intelligence. This gap in security measurement could hinder the safe and responsible development and deployment of AI technologies. AI

StepFun has released Step Image Edit 2, a 3.5 billion parameter image editing model that has achieved top rankings on the KRIS-Bench benchmark across multiple categories. This new version surpasses significantly larger models in performance and offers a rapid response time of 0.7 seconds.
