What is this
This is the SFT start-point checkpoint used to initialize online RL; the corresponding RL checkpoint is the released agent (see the collection).
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-sft \
--served-model-name scalecua --trust-remote-code --port 8000
Then follow REPRODUCE.md to run ScienceBoard evaluation.
Results
(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.
