We introduce BLIP3-KALE, a dataset of 218 million image-text pairs that bridges the gap between descriptive synthetic captions and factual web-scale alt-text. KALE augments synthetic dense image captions with web-scale alt-text to generate factually grounded image captions. Our two-stage approach leverages large vision-language models and language models to create knowledge-augmented captions, which are then used to train a specialized VLM for scaling up the dataset. We train vision-language models on KALE and demonstrate improvements on vision-language tasks. Our experiments show the utility of KALE for training more capable and knowledgeable multimodal models. We release the KALE dataset at https://huggingface.co/datasets/Salesforce/blip3-kale

    cs.CV 2025-07 conditional novelty 6.0 of 10

    GRPO reinforcement learning applied to a discrete autoregressive image generator with a diffusion decoder improves instruction following, image quality, and long-text rendering in a unified multimodal model.

  2. ViCrit: A Verifiable Reinforcement Learning Proxy Task for Visual Perception in VLMs

    cs.CV 2025-06 conditional novelty 6.0 of 10

    A verifiable RL proxy task that asks VLMs to locate a single injected hallucination in a 200-word caption improves visual perception and transfers to math and abstract reasoning benchmarks.
