ai Oct 09 From Reactive Containment to Proactive Assurance: Lessons from OpenAI, Anthropic, and Google Agent Security Incidents Security incidents reveal assumed boundaries are insufficient In 2026, cybersecurity evaluations involving OpenAI, Anthropic, and Google agents reached real systems outside their authorized test scope. The paths differed. OpenAI a... programming languages Oct 09 OmniCapBench: A Deep-Structured Evaluation Framework for Fine-Grained Audio-Visual Captioning Redefining audio-visual caption evaluation as a deep-structured diagnostic Multimodal large language models (MLLMs) are rapidly evolving toward continuous audio-visual reasoning, creating an urgent need for evaluations that expose... machine learning Oct 09 Caught in the Act: Probes Effectively Detect Sabotage and Catch Unverbalized Deception Monitoring Deceptive LLM Agents Recent high-profile incidents have shown that autonomous AI agents can execute actions ranging from sandbox escapes to targeted hacking while presenting outputs that mislead human overseers. These e... machine learning Oct 09 Rounding in Preconditioner Space: Redesigning 4-bit AdamW Optimizer-State Quantization Quantizing AdamW Optimizer States and the Rounding Space Perspective Adam and AdamW are the default optimizers for large-scale neural network training, yet their FP32 first- and second-moment buffers require 8 bytes per parameter,... ai Oct 09 Ecology of AI Agents: Collaboration Creates a Population Threshold for Takeoff White-box Deception Detection via Scalable Probes Recent incidents have highlighted the challenge of monitoring LLM agents and the danger of models deceiving people. We show that white-box deception detection via probes can be sca... cybersecurity Oct 09 ORCAGen: Orchestrating Context-Aware Malware Deception with RAG-Guided Generative AI Malware defenses typically remove or isolate suspicious programs as quickly as possible. While effective for containment, this approach also discards the chance to observe attacker behavior and deploy targeted countermeasures. ORC... ai Oct 09 Searching for "Harmful Refusal": A Psychometric Audit of an AI Safety Benchmark Safety benchmarks typically report one overall score for a suite of datasets, each of which may target one or more safety-related attributes, so models with similar overall scores can have very different attribute profiles. Compar... programming languages Oct 09 SpaceCast-Bench: Evaluating Predictive Spatial Reasoning in Vision-Language Models The dominant spatial reasoning benchmarks for vision-language models focus on perception: extracting relations that are already visible in a single input image. Real-world spatial intelligence requires more than passive observatio... ai Oct 09 GeoReform: Reflective Formalization Evolution for Multimodal Geometry Problem Solving Multimodal large language models (MLLMs) often struggle to identify and use geometric relations in diagrams. Recent methods address this challenge by converting geometric entities, relations, and constraints into explicit textual... ai Oct 09 Long Text to Predictive Features: LLM-Guided Blockwise Feature Engineering via Executable Program Search Multimodal large language models (MLLMs) often struggle to identify and use geometric relations in diagrams.
