Toward Trustworthy Difficulty Assessments: Large Language Models as Judges in Programming and Synthetic Tasks

arXiv — cs.CLTuesday, November 25, 2025 at 5:00:00 AM
  • Large Language Models (LLMs) like GPT-4o have been evaluated for their effectiveness in assessing the difficulty of programming tasks, specifically through a comparison with a Light-GBM ensemble model. The study revealed that Light-GBM achieved 86% accuracy in classifying LeetCode problems, while GPT-4o only reached 37.75%, indicating significant limitations in LLMs for structured assessments.
  • This development highlights the challenges faced by LLMs in accurately interpreting numeric and contextual cues essential for difficulty assessment in programming tasks. The findings raise concerns about the reliability of LLMs as evaluators in educational and competitive contexts.
  • The ongoing discourse around the capabilities and limitations of LLMs is underscored by similar studies questioning their stability and reliability across various applications. As LLMs are increasingly integrated into diverse fields, understanding their shortcomings is crucial for developing more effective AI systems and ensuring responsible deployment.

ClimateIQA: A New Dataset and Benchmark to Advance Vision-Language Models in Meteorology Anomalies Analysis
PositiveArtificial Intelligence
A new dataset named ClimateIQA has been introduced to enhance the capabilities of Vision-Language Models (VLMs) in analyzing meteorological anomalies. This dataset, which includes 26,280 high-quality images, aims to address the challenges faced by existing models like GPT-4o and Qwen-VL in interpreting complex meteorological heatmaps characterized by irregular shapes and color variations.
LLaVAction: evaluating and training multi-modal large language models for action understanding
PositiveArtificial Intelligence
The research titled 'LLaVAction' focuses on evaluating and training multi-modal large language models (MLLMs) for action understanding, reformulating the EPIC-KITCHENS-100 dataset into a benchmark for MLLMs. The study reveals that leading MLLMs struggle with recognizing correct actions when faced with difficult distractors, highlighting a gap in their fine-grained action understanding capabilities.
DriveRX: A Vision-Language Reasoning Model for Cross-Task Autonomous Driving
PositiveArtificial Intelligence
DriveRX has been introduced as a vision-language reasoning model aimed at enhancing cross-task autonomous driving by addressing the limitations of traditional end-to-end models, which struggle with complex scenarios due to a lack of structured reasoning. This model is part of a broader framework called AutoDriveRL, which optimizes four core tasks through a unified training approach.
