Molmo2: Open Weights and Data for Vision-Language Models with Video Understanding and Grounding

Molmo2 is a new open-source family of vision-language models that achieves state-of-the-art performance among open models, particularly excelling in video understanding and pixel-level grounding tasks. The research introduces 7 new video datasets and 2 multi-image datasets collected without using proprietary VLMs, along with an 8B parameter model that outperforms existing open-weight models and even some proprietary models on specific tasks.

FACTS Grounding: A new benchmark for evaluating the factuality of large language models

Researchers have introduced FACTS Grounding, a new benchmark designed to evaluate how accurately large language models ground their responses in source material and avoid hallucinations. The benchmark includes a comprehensive evaluation system and online leaderboard to measure LLM factuality performance.
