Clean Engineering, Unstable Measurement: A Preregistered Reliability Failure of Black-Box LLM Observers on Shared Endpoints

"Language-model judges now gate training data, score generations, and drive leaderboards. The judge is then a measurement instrument, resting on one rarely stated assumption: the same request, sent to the same model name, reads the same tomorrow. We audited that assumption in two preregistered campai..."

From Deceptive Outputs to Deceptive Mechanisms: A Causal Framework for Language-Model Deception Research

"Research and news coverage of language-model deception increasingly attributes human-like mental-state concepts to language models. Such claims can blur the distinction between behavior that looks deceptive and a mechanism that is actually deceptive. We introduce a causal taxonomy separating prior..."

Sequential Beats Joint: On the Interplay between On-Policy Distillation and RLVR

"Reinforcement learning with verifiable rewards (RLVR) and on-policy distillation (OPD) have emerged as two dominant methods for post-training reasoning LLMs. Prior work uses OPD's dense token-level supervision to complement the sparse RL reward, fusing the two signals within a single step: either as..."

Legibility is Not Interpretability: Comparing Judged and Actual Importance in Chain-Of-Thought Reasoning

"Reasoning traces from chain-of-thought models appear to offer a legible window into how a model arrives at its answer. A growing body of work treats them as such, using LLM judges to diagnose errors, evaluate faithfulness, and provide step-level supervision via process reward models and generative c..."

SENTINEL-RL: Offloading Topological Reasoning from LLM Agents in the Security Operations Center

Representational alignment yields generalizable safety in language models

"Aligning large language models (LLMs) is essential for their safe deployment. Current alignment methods mainly optimize observable responses, yet models remain vulnerable when the same harmful intent is recast in unfamiliar or adversarial forms that humans can easily recognize. Prototype theory offe..."

Rethinking On-Policy Distillation of Large Language Models II: One Training Example

"On-policy distillation (OPD) combines student-generated rollouts with dense token-level supervision from a teacher. Existing work has mainly studied its algorithmic behavior, leaving the role of training data unclear. We examine this role at the data-minimal limit by training on a single query. One-..."

Compile by Training: Turning Natural-Language Specifications into Local Neural Functions

DRACO: Fine-Grained Credit Assignment with Dynamic Rubrics for Long-Horizon Agent Training

"Reinforcement Learning from Verifiable Rewards works well when a task has a programmatic checker, but most long-horizon agent domains have none.

Terminal-Universe: Turning Agent Trajectories into Scalable Terminal Environments

Instruction Duplication as an Inference-Time Control Primitive

Knowledge Acquisition During Pre-training? Large Language Models Learn Better With Auxiliary Views

"Gaps remain in our understanding of how large language models (LLMs) acquire knowledge during pre-training.
