Logprob Reduction Fails to Verify Causal PII Suppression in LLMs

This paper shows that SAE-based feature interventions for suppressing PII leakage in LLMs, when evaluated only by log-probability reduction, often produce false positives. Across 36 cases, 47% appeared successful under logprob-only evaluation, but only 2.8% passed a multimetric framework with random direction controls. The authors identify two failure modes and propose causally grounded PII suppression via circuit-level localization and causal mediation analysis.

Why it matters: Provides concrete evidence that a common evaluation metric is unreliable)Skip and proposes a more rigorous methodology, directly impacting AI safety research.

Asymptotic Optimality of cμ-Rule for LLM Inference Scheduling under Memory Constraint

This paper studies LLM inference scheduling as an online queueing problem with finite KV-cache memory. The authors develop a fluid model that reduces the system to a multiclass single-server queue and derive a cμ priority rule where effective service rates account for computation, memory access, and memory capacity. They prove the rule minimizes cumulative holding cost in the fluid model and, for finite workloads, also minimizes completion time and maximizes output-token throughput. Experiments on an NVIDIA H800 show practical implementations reduce average latency while maintaining high throughput.

Why it matters: Provides a rigorous theoretical foundation and practical validation for a scheduling policy that improves LLM inference efficiency under memory constraints, directly relevant to serving systems.

Modelling lock-in of AI adoption through skill erosion

This paper presents a mathematical model showing that generative AI can improve immediate performance but erode human skills, leading to bistability and hysteresis between low-adoption/high-skill and high-adoption/low-skill states. The model derives exact skill distributions for users and non-users, and shows that AI adoption can become locked in due to history-dependent switching costs. It also finds asymmetric transitions: a single AI user can spread among experts if AI pay exceeds expert pay, while a single non-user can only reverse adoption if they regain sufficient skill before returning to AI.

Why it matters: Provides a rigorous theoretical framework for understanding AI adoption lock-in and skill erosion, with practical implications for policy and workforce planning.

Artifact-to-Capability: Diagnosing Breaks in Capability Formation of Self-Evolving Agents

This paper introduces a formal definition of capability formation from artifacts in self-evolving agents, proposing five sequentially dependent properties and a three-scale diagnosis method. In freestyle Gomoku, Reflexion, Voyager, and DGM all show standard proxy signals but exhibit distinct capability-formation breaks, such as legalization gain, compositional override, and loss-only drift. The findings demonstrate that signal-based evaluation cannot reliably determine whether a capability has formed.

Why it matters: Provides a concrete diagnostic framework and counterexamples that challenge common evaluation practices in self-evolving AI agents, offering practical value for researchers and developers.

Shuffled OPSD: When Semantic Consistency Hurts On-Policy Self-Distillation?

This paper introduces Shuffled OPSD, a variant of on-policy self-distillation that shuffles the words of the shared problem statement while keeping the teacher-only worked example intact. Across three math reasoning benchmarks and three Qwen3 model scales, it improves mean accuracy over both intact-target and Standard OPSD, with the largest gain of 3.52 points on Qwen3-1.7B. Controls show that shuffling the teacher-only example hurts accuracy, while word-level shuffling of the problem statement helps, challenging the assumption that semantic coherence is always beneficial.

Why it matters: Provides concrete, recent experimental evidence that disrupting input structure can improve self-distillation, offering a novel insight for AI training methodology.
