LLMs struggle with 2D data; vision pathway outperforms text serialization

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 2 sources

A new paper explores the challenges large language models face when processing 2D structured data by converting it into 1D sequences. Researchers found that this "serialization friction" hinders performance on tasks like matrix transpose and Conway's Game of Life. A vision-augmented pathway that preserves the 2D layout significantly outperformed a text-only pathway, suggesting that maintaining spatial structure is crucial for these types of tasks. AI

    When 2D Tasks Meet 1D Serialization: On Serialization Friction in Structured Tasks

    Large language models (LLMs) conventionally process structured inputs as 1D token sequences. While natural for prose, such linearization may introduce additional representational burden for tasks whose computation depends directly on explicit 2D structure, because row--column ali…
