The is a diverse, large-scale multimodal dataset used primarily for fine-tuning vision-language models. It consists of approximately 665,000 instruction-following samples that combine images with complex textual reasoning, designed to help models understand and describe visual content with high precision.

The "665K" refers to the number of entries, not the file size. When unzipped, the full image set requires substantial disk space—often dozens of gigabytes—depending on whether you are downloading the raw images or pre-processed features. 3.

A significant portion of the 665k dataset relies on external datasets like OCR-VQA. However, many original image URLs in these datasets are no longer active.
Some distributed versions of the 665k zip files use the Parquet format rather than standard JPG/PNG files. While efficient for storage, this requires an extra conversion step before the data can be used directly for training in many standard pipelines.
Fine-tuning on the 665k dataset consistently improves "Average Relative Performance" (ARP) for medium-sized models like TinyLLaVA 2.0B.
