AI2’s New Small Open-Source Model Performs as Well as Big Ones

Groundbreaking open-source AI model challenges industry giants: The Allen Institute for Artificial Intelligence (Ai2) has unveiled Molmo, a family of open-source multimodal language models that rival the performance of proprietary models from leading tech companies.

• Ai2 claims its largest Molmo model, with 72 billion parameters, outperforms OpenAI’s GPT-4o in tests measuring image, chart, and document understanding.
• A smaller Molmo model with just 7 billion parameters reportedly approaches the performance of OpenAI’s state-of-the-art model, highlighting Ai2’s efficient data collection and training methods.

Key innovations in data curation and training: Molmo’s impressive performance stems from a novel approach to data collection and model training, setting it apart from other large language models.

• Unlike models trained on billions of internet-scraped images and text samples, Molmo uses a carefully curated dataset of only 600,000 images.
• Human annotators provided detailed, multi-page descriptions of the images, speaking rather than typing to expedite the process.
• AI techniques converted the speech into data, reducing computing power requirements and accelerating training.

Implications for AI development and governance: The success of Molmo’s approach could have far-reaching consequences for the AI industry and efforts to govern AI development responsibly.

• Yacine Jernite, machine learning and society lead at Hugging Face, suggests that Molmo’s techniques could be valuable for meaningful governance of AI training data.
• Percy Liang, director of the Stanford Center for Research on Foundation Models, notes that training on higher-quality data can indeed lower compute costs.

Advanced capabilities and potential applications: Molmo demonstrates unique features that could enable more sophisticated AI interactions and applications.

• The model can “point” at elements within an image, identifying specific pixels that answer queries.
• This pointing capability could be crucial for developing web agents capable of interacting with user interfaces and performing complex tasks like booking flights.

Open-source advantage and industry impact: Ai2’s open-source approach to Molmo could accelerate AI innovation and challenge the dominance of proprietary models.

• The open nature of Molmo allows developers to build applications on top of it, potentially leading to more diverse and innovative AI solutions.
• Ai2 CEO Ali Farhadi argues that open-source AI models like Molmo can make more efficient use of resources and time compared to expensive proprietary models.

Limitations and future developments: While Molmo shows promise, it is not without limitations, and its true impact will depend on future developments and applications.

• In demonstrations, the model occasionally failed to locate specific elements in images, indicating room for improvement.
• The real significance of Molmo will lie in the applications developers build on top of it and how the AI community improves upon the model.

Broader implications for AI industry and investment: Molmo’s release comes at a time when investors are reassessing the potential returns on massive AI investments.

• Recent skepticism about returns on multitrillion-dollar AI investments has emerged in the past few months.
• Farhadi suggests that open-source models like Molmo, rather than expensive proprietary ones, may be key to realizing returns on AI investments.

Looking ahead: The future of open-source AI: The release of Molmo represents a significant step forward for open-source AI development, potentially reshaping the competitive landscape and accelerating innovation in the field.

• As developers begin to work with Molmo and build upon it, new applications and improvements are likely to emerge.
• The success of Molmo could inspire more research institutions and companies to pursue open-source AI development, fostering a more collaborative and transparent AI ecosystem.
