🚨Excited to release OS-Harm! 🚨 The safety of computer use agents has been largely overlooked. We created a new safety benchmark based on OSWorld for measuring 3 broad categories of harm: 1. deliberate user misuse, 2. prompt injections, 3. model misbehavior.

Frontier AI systems failed to reliably flag safety risks related to more than 40% of common safety facts tested in the SAGE‑Eval benchmark by Yueh-Han (John) Cheni, @guydav.bsky.social, and @brendenlake.bsky.social. nyudatascience.medium.com/even-the-top...

Even the Top LLM Failed to Reliably Flag Some Risks Related to 40% of Safety Facts
CDS’ SAGE‑Eval shows top‑performing AI models failed at least 42% of safety warnings in novel scenarios.

Fantastic new work by @johnchen6.bsky.social (with @brendenlake.bsky.social and me trying not to cause too much trouble). We study systematic generalization in a safety setting and find LLMs struggle to consistently respond safely when we vary how we ask naive questions. More analyses in the paper!

Failures of systematic generalization in LLMs can lead to real-world safety issues. New paper by @johnchen6.bsky.social and @guydav.bsky.social, arxiv.org/abs/2505.21828

Do LLMs show systematic generalization of safety facts to novel scenarios? Introducing our work SAGE-Eval, a benchmark consisting of 100+ safety facts and 10k+ scenarios to test this! - Claude-3.7-Sonnet passes only 57% of facts evaluated - o1 and o3-mini passed <45%! 🧵

What does it mean for #LLM output to be novel? In work w/ johnchen6.bsky.social, Jane Pan, Valerie Chen and He He, we argue it needs to be both original and high quality. While prompting tricks trade one for the other, better models (scaling/post-training) can shift the novelty frontier 🧵
