Lineage
The Hub card names allenai/Olmo-3-7B-Think-DPO as the base model. That id is not a page on this register.
How to run
Safetensors weights are on the Hugging Face repository. The parameter count on this page came from that index.
The Hugging Face model API lists the library as transformers.
Load it from huggingface.co/allenai/Olmo-3-7B-Think. This page does not add install steps that the Hub files do not state.
