AI2’s “Truly Open Source” OLMo LLM Signals Critical Shift Towards Democratized AI

1. OLMo is “completely open” LLM framework, providing full access to data, code, weights and tools to enable new research.
2. It addresses the lack of transparency in other models that limits scientific understanding of how LLMs actually work.
3. The open source release represents a major shift towards democratized, ethical and trustworthy AI development.
4. Early reaction from open source AI leaders is hugely positive, welcoming OLMo’s unprecedented openness.
5. Iterations will continue over time with different model sizes, data and capabilities.
6. OLMo has the potential to revolutionize both AI research and real-world deployment.

The non-profit Allen Institute for Artificial Intelligence (AI2) has introduced OLMo, a revolutionary new open source large language model framework. By providing full access to training data, code, model weights and evaluation tools, OLMo represents a critical shift towards democratized and transparent AI development.

Unlike other models that have included select components, OLMo’s “completely open” framework gives researchers unprecedented access at every stage. This includes pretraining data, training code, over 500 model checkpoints capturing performance at each 1000 training steps, and full evaluation suites used during development. All elements are licensed under Apache 2.0 for full reuse.

“Without access to training data, researchers cannot scientifically understand how a model works. It’s like drug discovery without clinical trials,” said project lead Dr. Hanna Hajishirzi. “OLMo will enable the community to properly study LLMs, which is critical for building safe and trustworthy AI.”

The launch comes as proprietary models like GPT-4 and Claude take the lead, while open source AI plays catch up. But open source continues gaining traction, as seen in Mistral’s recent competitive open source model leak and Meta’s release of Code Llama 70B. Still, some researchers argue open source AI brings unique dangers that must be addressed.

Nathan Lambert, an AI2 machine learning scientist, highlighted that “OLMo represents something entirely new on the axis of openness.” He explained it will “enable new ML research and deployment approaches not previously possible due to incomplete tools and information.”

Many open source AI leaders welcomed the news. Jonathan Frankle called it “a giant leap for open science,” while Hugging Face CTO Julien Chaumond said OLMo is “pushing the envelope.” Even Meta chief scientist Yann LeCun contributed a quote, stating open models have been “critical in driving innovation and development around generative AI.”

By providing full transparency and democratized access, OLMo represents a groundbreaking development set to shape the future landscape of AI research and deployment. AI2 plans to continue iterating on the framework with different sizes, data and capabilities over time.

For too long, progress in AI has been concentrated in the hands of Big Tech firms jealously guarding the inner workings of their models as trade secrets. This has severely hampered scientific inquiry and allowed potentially harmful biases and flaws to be propagated unchecked.

But now there is a chance for change. By empowering the broader research community to properly examine LLMs, OLMo can help accelerate discoveries to address pressing issues around fairness, safety and robustness. Its iterative open source nature also promotes inclusive participation to shape future developments.

In an AI arena dominated by closed proprietary systems rife with public distrust, OLMo offers a beacon of hope for responsible, ethical and democratized progress. Its public launch has been welcomed by open source AI leaders as a huge leap forwards. One can only hope that its unprecedented openness sparks a wider movement across the industry towards transparency and accessibility in AI. For if the democratization of AI is to succeed in serving all humanity, then opaque models that silently concentrate power must give way to frameworks like OLMo that bring all stakeholders together in the open pursuit of knowledge and understanding.
