\textsc{DiARC}: Distinguishing Positive and Negative Samples Helps Improving ARC-like Reasoning Ability of Large Language Models

arXiv:2606.26530v1 Announce Type: cross Abstract: The Abstraction and Reasoning Corpus (ARC;~\citealp{chollet2019measure}) contains tasks that require summarizing patterns from limited grid samples and predicting output grids. Recently, many large language model based approaches have attempted to transform it into a text-based reasoning task. However, methods based on open-source models have generally yielded unsatisfactory results, while those relying on closed-source models are too costly. Current efforts mainly focus on data augmentation, constructing ARC-like data for more comprehensive su

Why this matters
Why now

The paper published at arXiv highlights current limitations in open-source LLMs' reasoning abilities for complex tasks like ARC, indicating a push for more effective, less costly solutions.

Why it’s important

Improving LLM reasoning and pattern summarization from limited samples is crucial for advancing AI's capability beyond basic tasks, particularly for autonomous systems and agentic AI.

What changes

This research suggests a more efficient way to enhance logical reasoning in LLMs, potentially democratizing advanced AI capabilities currently costly or proprietary.

Winners
  • · Open-source AI developers
  • · Companies using open-source LLMs
  • · AI agents developers
Losers
  • · Proprietary LLM providers if open-source catches up
  • · Researchers relying solely on closed-source model superiority
Second-order effects
Direct
