Item Response Theory for AI Safety

Joshua Fonseca Rivera, Neil Shah, David Demitri Africa +1

Language models differ in how safely they behave and these differences are measured by safety benchmarks. But aggregated benchmark scores are hard to trust and interpret, because b…

Can AI agents conduct open-ended AI research? Early evidence from two case studies

Peter Kirgis, Sayash Kapoor, Andrew Schwartz +21

The paper evaluates whether current AI agents can independently conduct open‑ended AI research by having them attempt to solve the central questions of two unpublished NeurIPS subm…

Detecting CSAM Text-to-Image LoRAs From Weights

David Demitri Africa, Cate Heine, Nadine Staes-Polet +1

Low-rank adaptation (LoRA) fine-tuning has made it cheap and easy to customize open-weight image generation models for specific tasks, including the production of child sexual abus…

Persona Cartography: Charting Language Model Personality Traits in Weight Space

Luke Baines, Anton Gonzalvez Hawthorne, Mariia Koroliuk +4

Large language models exhibit recurring behavioural patterns -- personas -- that shape generalisation and safety, but we lack reliable tools for decomposing, measuring, and control…

Tool Use Enables Undetectable Steganography in Multi-Agent LLM Systems

Jimmy Laurence Rippin, Simon C. Marshall, David Demitri Africa +1

Increasingly autonomous agentic AI systems pose novel multi-agent risks, such as secret collusion via covert communication channels. The natural defence to these collusion attempts…

When Role-playing, Do Models Believe What They Say?

Benjamin Sturgeon, David Africa, Sid Black

Language models can state that "the Earth orbits the Sun" and, when role-playing Aristotle, assert the opposite. Recent work argues that persona adoption is fundamental to how lang…
