ScaleCUA-glm4.6v-osworld

A GLM-4.6V-Flash computer-use agent from ScaleCUA, trained for OSWorld. Stage: online-RL (RLVR).

This model was introduced in the paper SCALECUA: Scaling Computer Use Agents with Verifiable Task Synthesis and Efficient Online RL.

What is this

This is the online-RL checkpoint (the released agent). Its SFT start point is `extreme1228/ScaleCUA-glm4.6v-osworld-sft`. It reaches 66.5% 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`:

bash

pip install -U vllm
python -m vllm.entrypoints.openai.api_server --model extreme1228/ScaleCUA-glm4.6v-osworld \
  --served-model-name scalecua --trust-remote-code --port 8000

Then follow `REPRODUCE.md` to run OSWorld evaluation.

Results

66.5% on OSWorld (see the paper for the full table).

License

Weights are released for research; the model inherits the license of its base model (GLM-4.6V-Flash). Repository code is under the licenses in the GitHub repo.
