AgentHOI: Training‑Free Human‑Object Interaction Detection with Multimodal LLMs

The paper introduces AgentHOI, a framework that eliminates the need for HOI‑specific annotations by decomposing detection into context‑aware semantic reasoning and multifaceted spatial localization, leveraging GPT‑4o and GroundingDINO, and demonstrates strong zero‑shot and robustness performance on HICO‑DET and SWIG‑HOI benchmarks.

Can Hidden Activations Expose Multimodal Model Jailbreaks?

The paper reveals that large multimodal language models retain refusal signals in their hidden states even after jailbreak attempts, and proposes a training‑free detection method that leverages these signals to identify unsafe inputs across text and image modalities with strong generalization.
