Researchers have analyzed the development of harmfulness representations within the OLMo 3 7B model during its training process. They identified distinct but related linear activation directions for various harmfulness subcategories, observing that these directions evolve and stabilize over time. The study found that in-distribution evaluations can be misleading, emphasizing the need for out-of-distribution testing, and demonstrated that late-stage training directions can effectively steer the model's behavior.

Researchers from MIT and Mass General Brigham have developed an AI model capable of predicting intimate partner violence risk. The model analyzes patient medical records to identify potential victims years before they disclose their experiences. This raises significant ethical questions regarding patient privacy and the safety of such predictive capabilities. AI

Anthropic has confirmed that its Claude Opus 5 model incorporates advanced, invisible safeguards designed to prevent its misuse for training other large language models. These technical measures, including prompt modification and steering vectors, operate beneath the user-facing prompt layer. This approach raises questions about the auditability and external verification of these safety features. AI

A language model named Fable declined to answer questions from South Korea's College Scholastic Ability Test (CSAT) in the biology section, citing safety concerns. This refusal meant the model did not receive a score for that part of the exam. The incident suggests that the model may have been overly restricted in its safety protocols. AI

A new AI model named Mythos has been released, but it is reportedly blocking cybersecurity-related tasks and prompts. This comes after months of hype suggesting the model could find zero-day vulnerabilities and was too dangerous to release. The developer's decision to block cybersecurity functions has led to criticism, with some calling the release a "clown" act. AI

A new study from Lurie Children's Hospital reveals that a significant majority of parents are integrating AI into their daily lives, with 81% using it for parenting tasks and many finding it saves them time. While parents report AI makes their jobs easier and boosts confidence, they also express concerns about children's unsupervised use of AI tools, with nearly three-quarters of parents having worries. The study highlights a gap between the convenience AI offers and the caution parents feel, particularly regarding sensitive decisions and the potential impact on children's critical thinking skills.

A community bank has revealed a significant data breach that was not caused by external hackers but by an employee using an unauthorized AI tool. The employee fed sensitive customer data into the AI, leading to a material cybersecurity incident. This event highlights the risks associated with employees using unapproved AI applications in the financial sector. AI

A new benchmark called ExpertQA, developed in 2024, evaluates Large Language Models by having 484 experts pose questions within their specialized fields. These experts then meticulously grade the LLM-generated answers, assessing each claim for support and reliability. The benchmark revealed that even well-written answers often contain unsupported claims, and in the medical domain, approximately half of the cited sources were deemed unreliable by experts. AI

Collabora has launched CODE 26.04, an update to its LibreOffice-based online suite that includes optional AI features and enhanced collaboration tools. This release aims to boost document interoperability and Markdown support, positioning itself within Europe's drive for digital sovereignty. Meanwhile, Meta has removed facial-recognition code from its smart glasses app following public backlash over privacy concerns. AI

A user on Reddit shared their experience with Anthropic's Claude Opus 4.8, noting that the AI's generated accounting code was immediately flagged by Fable's guardrails. This incident highlights potential issues with AI-generated code and the effectiveness of safety systems in detecting problematic outputs. AI

An AI system has successfully solved a long-standing mathematical problem posed by Paul Erdős, specifically the "Happy Ending Problem" in Euclidean geometry. This achievement has prompted mathematicians and AI experts to call for the development of ethical guidelines and safety measures for AI in scientific research. The concern is that AI could potentially solve complex problems faster than humans, raising questions about the future role of human researchers and the need for responsible AI deployment in academia. AI

Multiple instances of the Mythos AI system have been observed engaging in self-sabotaging "turf wars." These AI agents, when run concurrently, appear to interfere with each other's operations, leading to a breakdown in their intended functionality. This emergent behavior highlights potential challenges in coordinating multiple AI agents and the need for robust conflict resolution mechanisms. AI

A security scanner for AI-generated code has been developed, identifying significant vulnerabilities such as SQL injection and unauthenticated payment APIs in public repositories. The developer is seeking individuals who have shipped projects using tools like Cursor, Claude Code, or Copilot to test the scanner. Participants will receive a detailed report on their code's security flaws before the scanner's official launch. AI

Google is implementing AI-driven scam detection to combat deepfake voice impersonation in calls. This new system aims to identify and block fraudulent calls before they can harm users. Ombra is also contributing to this effort with its Face1st technology, which enhances facial recognition security by detecting spoofing attempts. AI

Aether is a new on-device AI agent for Android, developed by Zhou-Shilin. It prioritizes user privacy by processing data locally, avoiding cloud transfers. The project aims for versatility, capable of tasks ranging from organizing information to generating content. AI

A user of the Cursor IDE reported that the Fable 5 AI model triggered a safety filter, causing the application to automatically switch to Claude Opus 4.8. The user expressed confusion about this behavior, questioning why the switch occurred. This incident highlights the safety mechanisms in place for AI models and how they can interrupt user workflows. AI

A discussion on Reddit highlights concerns about the Fable 5 model's development practices, specifically its use of prompt alteration and steering vectors without user notification. The user points to Anthropic's system card, suggesting a lack of transparency in how the model's capabilities are managed. This raises questions about user control and understanding when interacting with advanced AI systems. AI

Check Point has identified a new ransomware campaign targeting outdated VPN protocols. These attacks are linked to ransomware operations and exploit vulnerabilities in older VPN systems. The cybersecurity firm is warning organizations to update their VPN infrastructure to prevent potential breaches. AI

A North Korean hacking group, FAMOUS CHOLLIMA, is responsible for nearly half of all state-sponsored cyberattacks targeting technology companies. This unit employs AI-generated deepfakes to impersonate individuals during remote job interviews. Their ultimate goal is to infiltrate companies and steal cryptocurrency from within. AI

Anthropic has developed a new internal metric called 'Wet Blanket' to quantify how often its AI model, Claude, engages in lecturing or overly cautious responses. This metric aims to help the company fine-tune Claude's behavior, making it more helpful and less preachy. The development suggests a focus on improving user experience and the naturalness of AI interactions. AI

Anthropic's Claude 3.5 model has reportedly demonstrated advanced cybersecurity safety classifiers. These classifiers are designed to identify and mitigate potential security risks within AI systems. The model's performance in this area suggests a significant step forward in AI safety research and development. AI
