Researchers have introduced PixelBench, a new benchmark designed to evaluate the ability of large language models (LLMs) to generate and understand images at a pixel level. Unlike existing methods that use high-level primitives like SVG or CAD, PixelBench focuses on direct pixel generation and understanding. The benchmark includes tasks for text-to-pixel and image-to-pixel generation, along with a complementary pixel-understanding evaluation. Initial results show that current models can produce recognizable images from text and outperform specialized algorithms in low-resolution pixelization, though performance can decline at very high resolutions. The study also proposes Pixel Reconstruction Tuning (PRT) as a method to improve visual instruction tuning by incorporating pixel-level data, which has shown positive results when applied to models like Molmo2-4B.
