The Allen Institute for AI (Ai2) is a non-profit research institute in Seattle, founded by Paul Allen in 2014, that makes fully open AI models such as Olmo.
In plain words
Ai2 does AI research aimed at real-world impact, including open models, data, robotics and conservation. Its Olmo models are fully open: besides the model weights, Ai2 releases the training data, code and reports, so others can study and rebuild the whole process. It also runs projects such as Semantic Scholar.
A quick example
Imagine a university lab that wants to study how a language model's training data affects its answers. With Olmo, it can download not just the model but the data it was trained on.
Where you'll meet it
- Fully open language models for research.
- AI for conservation and robotics.
