+# DR Tulu-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).
+For more details on DR Tulu please **read our [paper](https://allenai.org/papers/drtulu)**!
+
+# 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.
+Or check out our [demo](https://dr-tulu.github.io/)!
+
+# Evaluation Results
+
+We provide evaluation instructions in [our github](https://github.com/rlresearch/dr-tulu).
