# DR Tulu SFT 8B

This is the SFT checkpoint of DR Tulu, an open deep research agent trained on top of [Qwen3-8B](https://huggingface.co/Qwen/Qwen3-8B).

This model has undergone SFT training on [this dataset](https://huggingface.co/datasets/rl-research/dr-tulu-sft-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/)!
