Sep 25, 2024, 01:50 PM

The Allen Institute for AI (AI2) has released the Multimodal Open Language Model (Molmo), a state-of-the-art open-source AI model. Molmo is available in 1B, 7B, and 72B-parameter sizes and has been shown to outperform proprietary models such as GPT-4V, Claude 3.5 Sonnet, and Flash. The model's performance is attributed to its focus on data quality over quantity, utilizing a meticulously curated dataset called PixMo. Molmo's capabilities include understanding and acting on multimodal data, enabling rich interactions in both physical and virtual worlds. The release includes four model checkpoints: MolmoE-1B, Molmo-7B-O, and others, making it the most capable open-source AI model to date. Human preference for the 72B model is on par with top API models. The dataset PixMo was curated over 9 months.
