New from 404 Media: Meta announced Muse, its AI agent that can book restaurants for you. We've seen internal Meta messages showing Meta is actually testing having these calls being made by human beings in call centers. In those tests its not AI, it's just a person www.404media…

"hallucinated references disproportionately assign credit to already prominent and male scholars, suggesting that LLM-generated errors may reinforce existing inequities in scientific recognition" arxiv.org/abs/2605.07723

[2605.07723] LLM hallucinations in the wild: Large-scale evidence from non-existent citations arxiv.org
AI Weekly's analysis →
  • Researchers audited 111 million references across 2.5 million papers on arXiv, bioRxiv, SSRN, and PubMed Central to find non-existent citations at scale.
  • They estimate 146,932 hallucinated citations in 2025 alone, concentrated in fields with rapid AI uptake and in small or early-career author teams.
  • Fake citations disproportionately credit already prominent and male scholars, and existing preprint moderation catches only a fraction, the paper says.

US: In the latest sign that artificial intelligence is fueling higher health care costs, a group of insurers released a report Thursday claiming that hospitals’ use of A.I. was responsible for nearly $1 billion in additional expenses over two years. www.nytimes.com/2026/09/24/…

  • The Blue Cross Blue Shield Association attributes about $942 million in extra plan costs between 2023 and 2025 to hospital AI coding tools.
  • Hospitals were paid nearly $12,000 more per case on average as AI flagged secondary diagnoses without matching changes in treatment.
  • More than 60% of hospital systems have adopted AI coding tools that read lab reports and clinician notes.

A "radical intentionalist," writes Eryk Salvaggio, treats an AI model as a 'mind' to be interpreted rather than a product that was designed. It is "a strange and dangerous relationship for designers to have with a product they are literally designing," he writes — and worse as…

To Make AI Rules, Policymakers Must Resist the Influence of ‘Radical Intentionalists’ techpolicy.press
AI Weekly's analysis →
  • METR's Hugging Face post-mortem used 'believed' 21 times to describe the agents; add 'think' and 'thought' and mentions top 75.
  • Eryk Salvaggio argues a 'radical intentionalist stance' treats language models as autonomous believers, sidelining the design choices engineers actually made.
  • He calls the Sanders-Casar bill 'disappointing' for centering extinction fears and urges regulation grounded in architecture, not 'superintelligence.'

“The emperor is a fan of Flock,” a man dressed as Darth Vader told a San Diego City Council meeting last month.... “We must continue utilizing Flock technologies so that we can follow and surveil the rebel scum.” www.nytimes.com/2026/09/18/o...

‘Our new paper offers a rare look inside the “black box” of algorithmic hiring, showing that these tools increase racial bias and shut the same people out of jobs everywhere they apply’ hai.stanford.edu/news/ai-hiri...

AI Hiring Tools Can Yield Racial Bias and Systemic Rejection | Stanford HAI hai.stanford.edu
AI Weekly's analysis →
  • A Stanford HAI study of 4 million applications found 26% of Black applicants faced AI-screened positions that discriminated against their racial group.
  • Roughly 40,000 more applications would have advanced if the AI tool had recommended candidates at equal rates across racial groups.
  • Ten percent of applicants who submitted four applications screened by the same vendor were rejected from all of them, exceeding independent-probability expectations.

There Will Be a Scientific Theory of Deep Learning arxiv.org
AI Weekly's analysis →
  • A team of fourteen researchers argues that a scientific theory of deep learning is emerging, and proposes calling it 'learning mechanics.'
  • They point to five converging strands: solvable settings, tractable limits, neural scaling laws, hyperparameter theories, and universal behaviors across models.
  • The framing casts learning mechanics as deep learning's 'physics,' with mechanistic interpretability playing the 'biology' role in the same field.
