How to run
The Hugging Face model API lists the library as transformers.
Load it from huggingface.co/allenai/specter2_base. This page does not add install steps that the Hub files do not state.
Agent capabilities
This model publishes no chat template, so there is nothing to inspect. That is not evidence of missing support — many base models and some releases simply ship without one.
