Pass@k Metric for RLVR: A Diagnostic Tool of Exploration, But Not an Objective

arXiv — cs.LGFriday, November 21, 2025 at 5:00:00 AM
  • The pass@k metric has emerged as a significant tool in assessing the reasoning abilities of Large Language Models, focusing on the probability of obtaining correct solutions from multiple samples.
  • This development is crucial as it underscores the limitations of using pass@k as an optimization objective, particularly in scenarios where exploration is vital for effective learning.
  • The discourse around reinforcement learning continues to evolve, with various approaches being explored to enhance LLM performance, including self-play and confidence-aware reward models, indicating a broader trend towards refining AI training methodologies.

False Sense of Security: Why Probing-based Malicious Input Detection Fails to Generalize
NegativeArtificial Intelligence
Recent research highlights the limitations of probing-based approaches for detecting malicious inputs in Large Language Models (LLMs). Despite their potential, these methods often fail to generalize, as they tend to identify superficial patterns rather than the semantic harmfulness of inputs. Controlled experiments confirm that probes primarily learn instructional patterns and trigger words, raising concerns about the safety and reliability of LLMs in practical applications.
