| # JEV-Computer-Use: System-One Decision Agent for Computer & Browser Use |
|
|
| **JEV-Computer-Use** is a fast System-One decision model designed for high-speed Computer Use and Browser Navigation. Unlike traditional vision-language agents that output slow, verbose text reasoning before each mouse click, JEV uses a **single-readout candidate slot formulation**, outputting calibrated discrete action probabilities in a single forward pass. |
|
|
| ## 🚀 Key Features |
| - **Ultra-fast Execution**: Single-token action readout ($A, B, C...$) enables sub-second decision latency. |
| - **Online Interactive GRPO**: Built-in Group Relative Policy Optimization training with real headless Chromium (Playwright). |
| - **VLM Verifier**: Automated semantic verification using Qwen Vision-Language judge. |
| - **Calibrated Policy**: Trained with combined Cross-Entropy, Brier calibration loss, and analytical closed-form KL regularization. |
