MolmoWeb: An open agent for automating web tasks
Allen Institute (AI2)
Molmo released MolmoWeb, an open-source visual web agent built on their Molmo 2 multimodal model in 4B and 8B parameter sizes that can navigate and complete browser tasks by interpreting screenshots. The 8B model achieves 78.2% on WebVoyager, 42.3% on DeepShop, and 49.5% on WebTailBench benchmarks, outperforming other open-weight agents like Fara-7B and some proprietary models like GPT-4o. The release includes training code, a dataset of 36K human demonstrations plus synthetic trajectories, evaluation tools, and infrastructure enabling researchers and developers to build and customize web agents without relying on proprietary systems.
