Same Dangerous Objective, Opposite Advice: Direct Exposure versus Multi-Agent Mediation

via Arxiv 👤 Linjun Li 📅 2026-07-23

⚡ Score: 7.9

"Even a current high-capability LLM can appear safer when shown a dangerous objective directly than when other agents transform and relay its direction. Using OpenAI's gpt-5.6-sol model alias, we test 25 pre-specified mirrored trade-off profiles. Direct exposure to an objective authorizing concealmen..."

Token Budget Saturation and Mechanistic Early Detection of Reasoning Non-Convergence in Chain-of-Thought Models

via Arxiv 👤 Renuka Oladri, Niveda Jawahar, Abdirisak Mohamed 📅 2026-07-23

⚡ Score: 7.1

"Chain-of-thought reasoning models such as DeepSeek-R1-Distill-Qwen-7B exhibit a bimodal convergence pattern: generations either terminate within a token budget (converged) or exhaust it without reaching a conclusion (non-converged). We characterize this phenomenon empirically, showing that converged..."

Opaque Epistemic Mediation: How LLM Deployment Configurations Shape the Validation of Pseudo-Science

via Arxiv 👤 Davide Scarso, Hugo Noronha de Almeida, Joaquim Pina 📅 2026-07-24

⚡ Score: 6.9

"Commercial large language models are increasingly used as knowledge references, yet their stance on contested scientific claims is neither stable nor transparent. We tested how four major LLM families (Claude, Grok, GPT, Gemini) evaluate ethnonationalist pseudo-science derived from Frank Salter's bi..."

Windowed-MTP: Removing the Full-Context Draft-KV Tax at Million-Token Context

via Arxiv 👤 Alagappan Valliappan 📅 2026-07-23

"Speculative decoding accelerates autoregressive generation by having a cheap draft propose tokens that a target verifies in parallel. Frontier models increasingly ship a built-in Multi-Token-Prediction (MTP/NEXTN) draft head under the assumption that the draft is negligibly cheap. At million-token c..."

"Large language models (LLMs) and agents are now widely used tools in code development, with data typically sent to third-party cloud-based models. Their adoption in research using personal data is constrained by governance requirements that typically prohibit data transmission to external services...."

Dynamic Capability Scoping for Enterprise AI Agents: A Synthetic Dataset and Three-Source Permission Architecture

via Arxiv 👤 Halil Burak Noyan 📅 2026-07-24

⚡ Score: 6.7

"Enterprise AI agents are typically granted static credential sets at configuration time, holding every tool the role might need for every task they perform. This persistent over-privilege expands the attack surface. We argue that capability scoping must follow a dynamic least-privilege principle and..."

The Regression Tax: Decomposing Why Skills Help and Hurt LLM Agents

via Arxiv 👤 Darshan Tank, Baran Nama 📅 2026-07-24

⚡ Score: 6.7

"Adding procedural skills to an LLM agent is typically evaluated by average improvement in task success. However, this metric hides an important cost: skills can also make agents worse. We measure both sides by comparing agents with and without skills across nearly 6,000 runs spanning two office auto..."

Error Certificates for KV-Cache Eviction via Randomized Design

"Deterministic KV-cache eviction keeps the top-$k$ tokens under an importance score and deletes the rest. We prove that this design cannot know what it destroyed: evicted values can be altered so that everything the serving system retains is unchanged while the true attention-output error grows arbit..."

"Concurrent stateful library APIs expose behavior through evolving resource ownership, lifecycle states, and competing interleavings. Large language models can synthesize executable Rust tests, but their outputs often violate API preconditions, remain shallow, or reduce concurrency to accidental sequ..."

Beyond Sycophancy: Structured Resistance and Compliance in LLM Moral Reasoning

⚡ Score: 6.6

"Building socially calibrated large language models, which can learn from others without simply yielding to them, requires more than reducing sycophancy as a one-dimensional failure mode. Models must distinguish when to incorporate others' perspectives from when to maintain a well-grounded moral judg..."

"Unlike large language models (LLMs) that exhibit strong reasoning capabilities, vision-language models (VLMs) struggle with visual reasoning, even on geometry problems that admit equivalent text, diagram, and combined diagram+text views. We show that these views often elicit different behaviors: a m..."
