Molmo 2 is a family of open vision-language models (VLMs) by the Allen Institute for AI (Ai2), released on December 16, 2025. The family includes three variants (4B, 8B, 7B-O) and extends the original Molmo with video analysis, multi-image reasoning, and spatiotemporal grounding (video pointing and tracking). All weights, training data, and evaluation tools are freely available under Apache 2.0. According to Ai2's technical report, the 8B model outperforms the predecessor Molmo 72B and beats proprietary models such as Gemini 3 Pro on video tracking tasks.
