8. The vibes are off at OpenAI

摘要：OpenAI is in a relatively precarious position. The company is and has been a funding behemoth - just over a week ago, it closed $122 billion in funding at a post-money valuation of $852 billion. It's potentially planning

9. Unionized ProPublica staff are on strike over AI, layoffs, and wages

摘要：Unionized staff at ProPublica, one of the country's leading nonprofit newsrooms, are walking off the job for 24 hours beginning Wednesday and asking the public to honor a digital picket line. The roughly 150 members of t

10. Introducing the Child Safety Blueprint

摘要：Discover OpenAI’s Child Safety Blueprint—a roadmap for building AI responsibly with safeguards, age-appropriate design, and collaboration to protect and empower young people online.

11. Pramana: Fine-Tuning Large Language Models for Epistemic Reasoning through Navya-Nyaya

摘要：arXiv:2604.04937v1 Announce Type: new Abstract: Large language models produce fluent text but struggle with systematic reasoning, often hallucinating confident but unfounded claims. When Apple researchers added irrelevan

12. Operational Noncommutativity in Sequential Metacognitive Judgments

摘要：arXiv:2604.04938v1 Announce Type: new Abstract: Metacognition, understood as the monitoring and regulation of one's own cognitive processes, is inherently sequential: an agent evaluates an internal state, updates it, and

13. Proximity Measure of Information Object Features for Solving the Problem of Their Identification in Information Systems

摘要：arXiv:2604.04939v1 Announce Type: new Abstract: The paper considers a new quantitative-qualitative proximity measure for the features of information objects, where data enters a common information resource from several s
