ScaleCUA-glm4.6v-scienceboard

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

📄 Paper: SCALECUA: Scaling Computer Use Agents with Verifiable Task Synthesis and Efficient Online RL
💻 Code: https://github.com/THUDM/SCALE-CUA
🤗 Collection: https://huggingface.co/collections/extreme1228/scalecua-6a4cad5e3c80a230622eaff3 · 🤖 ModelScope

What is this

This is the online-RL checkpoint (the released agent). Its SFT start point is extreme1228/ScaleCUA-glm4.6v-scienceboard-sft. It reaches 49.4% on ScienceBoard.

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:

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

Then follow REPRODUCE.md to run ScienceBoard evaluation.

Results

49.4% on ScienceBoard (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.
