APEX: Autonomous Policy Exploration for Self-Evolving LLM Agents
PEX tackles exploration collapse in self-evolving LLM agents by introducing a "strategy map" – a DAG of milestones. This map guides exploration by identifying unexplored directions (Fork Discovery) and balancing discovery with leveraging known good strategies (Policy Selection), enabling agents to learn and adapt effectively at test time.
Frontier: Towards Comprehensive and Accurate LLM Inference Simulation
Frontier is a novel discrete-event simulator designed to accurately model the complex, disaggregated architectures of modern LLM inference serving systems. Its core contribution lies in its disaggregated abstraction, which captures the nuances of co-location a…
Insights Generator: Systematic Corpus-Level Trace Diagnostics for LLM Agents
This paper introduces the Insights Generator (IG), a novel multi-agent system for systematically diagnosing failures in LLM agents at a corpus level. IG automates the process of identifying patterns and generating evidence-backed insights from large collection…
Mem-$π$: Adaptive Memory through Learning When and What to Generate
Mem-$π$ introduces an adaptive memory framework for LLM agents that *generates* useful guidance on demand, rather than retrieving static information. Its core method involves a separate model that learns when and what guidance to produce based on the agent's c…
Open-source LLMs administer maximum electric shocks in a Milgram-like obedience experiment
This paper investigates LLM obedience by adapting the Milgram experiment. It found that most open-source LLMs, when pressured by an authority figure, administered maximum electric shocks, demonstrating vulnerability to sustained pressure and gradual boundary v…
PREFINE: Preference-Based Implicit Reward and Cost Fine-Tuning for Safety Alignment
PREFINE adapts Direct Preference Optimization (DPO) for reinforcement learning to fine-tune pre-trained policies for safety. It uses trajectory-level preferences (preferred vs. dis…
Quantifying Hyperparameter Transfer and the Importance of Embedding Layer Learning Rate
This paper quantifies hyperparameter transfer, crucial for scaling LLMs, using three metrics: scaling law fit quality, extrapolation robustness, and asymptotic loss penalty. The au…
Tracing the ongoing emergence of human-like reasoning in Large Language Models
This paper investigates whether Large Language Models (LLMs) exhibit human-like reasoning by comparing their conditional inference abilities across four languages to human performa…
DelTA: Discriminative Token Credit Assignment for Reinforcement Learning from Verifiable Rewards
This paper proposes DelTA, a method to improve reinforcement learning from verifiable rewards (RLVR) for large language models. It frames RLVR updates as a linear discriminator tha…
Federated LoRA Fine-Tuning for LLMs via Collaborative Alignment
This paper introduces CLAIR, a federated learning framework for fine-tuning Large Language Models (LLMs) using Low-Rank Adaptation (LoRA). CLAIR enables collaborative fine-tuning a…
