What you can do with it
The Allen Institute for AI's public playground offers a hands-on way to explore its open language and multimodal models. It is especially useful for learning how open research models behave, comparing outputs, and exploring features such as OlmoTrace, which connects matching response passages with examples from a model's training data.
What’s included for free
Ai2 describes its playground access as a free research demo. Available models and capacity can change; it is intended for scientific and educational experimentation rather than guaranteed production service.
Demos may have queues or temporarily unavailable compute.
Available models
Model availability can differ by plan and change over time.
