# DR Tulu-No-RLER-8B

This is the RL checkpoint of DR Tulu, an open deep research agent trained on top of [rl-research/DR-Tulu-SFT-8B](https://huggingface.co/rl-research/DR-Tulu-SFT-8B).

This model has undergone RL training on [this dataset](https://huggingface.co/datasets/rl-research/dr-tulu-rl-data).
**This model is trained without RLER**, and is an **ablation model** for analysing the effect of RLER.

Our main model can be found [here](https://huggingface.co/rl-research/DR-Tulu-8B).

# 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](https://github.com/rlresearch/dr-tulu) 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](https://allenai.org/responsible-use).

## Training

The script used to train this model can be found [here](https://github.com/rlresearch/dr-tulu/blob/rl/rl/open-instruct/train_dr_tulu.sh).
