This model has undergone RL training on this dataset. This model is trained without RLER, and is an ablation model for analysing the effect of RLER.

Our main model can be found here.

Inference and Usage

This model has been trained for tool-use using the dr-agent-lib framework. As such, running it out of the box with HuggingFace or vLLM will not work well!

See our github for more details on installation and how to run our model.

Intended uses & limitations

This model is licensed under Apache 2.0. It is intended for research and educational use in accordance with Ai2's Responsible Use Guidelines.

Training

The script used to train this model can be found here.
