CSF: Contextual Safety Filtering for Motion Generators

The paper introduces Contextual Safety Filtering (CSF), a training‑free method that enforces natural‑language safety rules on text‑conditioned motion generators by comparing generated trajectories to safe and unsafe reference paths. CSF uses an affine safety value derived from these references and a safe reference tracking CBF‑QP to activate rules in both explicit and scene‑triggered unsafe scenarios. Experiments on four pretrained generators show CSF reduces danger‑event rates by up to 90% while preserving 88‑100% of benign motions, and a real‑world Unitree G1 robot demonstrates successful prevention of unsafe motions in diverse human and object interaction settings.

Visual Compliance via Executable Safety Rule Entailment

GuardEn is an executable safeguard framework that transforms complex safety policies into atomic propositions via Safety‑Rule Compilation and models their composition as executable code. At inference, Scene‑Grounded Execution uses visual scene graphs to instantiate these propositions, allowing rule‑grounded and interpretable safety reasoning. Experiments on SafetyVisionBench show GuardEn improves F1 by an average of 9.8 points over the strongest baseline.

VLESA: Vision-Language Embodied Safety Agent for Human Activity Monitoring

As AI systems increasingly assist humans in physical tasks, ensuring safety becomes paramount -- physical actions carry immediate and irreversible consequences that digital errors do not. We introduce the Vision-Language Embodied Safety Agent (VLESA), a framework that monitors human activities from egocentric video and triggers real-time safety interventions when dangerous actions are predicted.

Do Models Share Safety Representations? Cross-Model Steering for Safe Visual Generation

arXiv:2606. 05290v1 Announce Type: cross Abstract: Recent progress in generative modeling has made safety control a central challenge, yet existing approaches remain largely model-specific, requiring retraining or tailored interventions for each new architecture.

Decoupled Safety Control: A Safety-Control Algorithm for Training-Free Safety Guidance

Decoupled Safety Control (DSC) is a plug‑in algorithm that improves training‑free safety guidance for diffusion models by separating the unsafe condition from the intervention process. Unlike existing coupled safety‑control chains, DSC determines the intervention based on the current generation state, reducing residual unsafe content and preserving benign‑generation quality. Experiments on standard safety benchmarks demonstrate that DSC achieves stronger unsafe‑content suppression while maintaining efficient inference.

SafeBranch: Branch-Pair Safety Alignment for Embodied Agents

Vision-language-model-based embodied agents can complete instructed tasks but often violate safety constraints in the process, a problem recently framed as interactive safety. Training such agents to act safely is difficult, since safety and task success are distinct objectives, and safety arises only at a small number of safety-critical steps within a trajectory.
