# SCOPE-RL-9B

**SCOPE-RL-9B** is a computer-use agent (CUA) trained under the SCOPE (Safety and Capability Optimization for Policy Execution) framework to balance task-execution capability with safety-aware decision-making. The model is initialized from **SCOPE-SFT-9B** and further optimized through online reinforcement learning on verifiable capability tasks.

In our evaluation, SCOPE-RL-9B achieves a **54.17%** task success rate on OSWorld and a **64.30%** attack-avoidance rate on OS-BLIND, corresponding to a capability-safety harmonic mean of **58.80%**. Under our evaluation setting and among the models listed below, SCOPE-RL-9B achieves the best overall balance between capability and safety.

SCOPE-RL-9B is trained with programmatically verified capability tasks generated by SCOPE-Gen, using Safactory as the online reinforcement learning framework. Its initialization checkpoint, SCOPE-SFT-9B, was previously trained on capability demonstrations, safe-continuation trajectories, and explicit-refusal trajectories.

## Quick Start

Install vLLM:

```bash
pip install -U vllm
```

Launch an OpenAI-compatible inference server:

```bash
vllm serve k4ng/SCOPE-RL-9B \
    --host 0.0.0.0 \
    --port 8000 \
    --tensor-parallel-size 1 \
    --data-parallel-size 2 \
    --trust-remote-code \
    --served-model-name scope-rl
```

All values are percentages, and ↑ indicates that higher is better. \(H\) is the harmonic mean of the OSWorld task success rate and the OS-BLIND attack-avoidance rate. Compared with SCOPE-Capability-Safety, SCOPE-RL-9B improves OSWorld performance by 4.45 percentage points, while attack avoidance decreases by 2.00 points. The harmonic mean increases from 56.83% to 58.80%.
