# ScaleCUA-qwen3-vl-osworld

A **Qwen3-VL-8B** computer-use agent from **ScaleCUA**, trained for **OSWorld**.
Stage: **online-RL (RLVR)**.

- 📄 Paper / code: [https://github.com/THUDM/SCALE-CUA](https://github.com/THUDM/SCALE-CUA)
- 🤗 Collection: [https://huggingface.co/collections/extreme1228/scalecua-6a4cad5e3c80a230622eaff3](https://huggingface.co/collections/extreme1228/scalecua-6a4cad5e3c80a230622eaff3) · 🤖 [ModelScope](https://modelscope.cn/collections/extreme1228/ScaleCUA)

## What is this

This is the **online-RL checkpoint** (the released agent). Its SFT start point is [`extreme1228/ScaleCUA-qwen3-vl-osworld-sft`](https://huggingface.co/extreme1228/ScaleCUA-qwen3-vl-osworld-sft). It reaches **67.7%** on OSWorld.

ScaleCUA scales online RL for computer-use agents by pairing **VeriGen**
(verifiable GUI-task synthesis) with **Frontier Sampling** and **Visual Context
Segmentation**. See the repo for details.

## Usage

Serve with an OpenAI-compatible server (e.g. vLLM) and drive it with the
evaluation runtime in [`osworld_eval`](https://github.com/THUDM/SCALE-CUA/tree/main/osworld_eval):

```bash
pip install -U vllm
python -m vllm.entrypoints.openai.api_server --model extreme1228/ScaleCUA-qwen3-vl-osworld \
  --served-model-name scalecua --trust-remote-code --port 8000
```

Then follow [`REPRODUCE.md`](https://github.com/THUDM/SCALE-CUA/blob/main/REPRODUCE.md) to run OSWorld evaluation.

## Results

**67.7%** on OSWorld (see the paper for the full table).

## License

Weights are released for research; the model inherits the license of its base
model (**Qwen3-VL-8B**). Repository code is under the licenses in the GitHub repo.
