UI-MOPD: Multi-platform On-Policy Distillation for Continual GUI Agent Learning
We build cross-platform GUI agents that can operate both desktop and mobile interfaces through a unified training framework.
Research
UI-MOPD introduces a two-stage training pipeline:
- Stage 1: Supervised Fine-Tuning (SFT) on platform-specific teacher models
- Stage 2: Reinforcement Learning distillation (DAPO) with multi-teacher on-policy guidance
Our student model (8B) learns from multiple 32B teacher models to achieve strong cross-platform GUI interaction capabilities. All models are based on Qwen3-VL-Thinking (thinking/reasoning variants).
Models
| Model | Size | Description |
|---|---|---|
| Qwen3-VL-32B-Thinking-Desktop-Teacher | 32B | Desktop platform teacher (thinking) |
| Qwen3-VL-32B-Thinking-Mobile-Teacher | 32B | Mobile platform teacher (thinking) |
| Qwen3-VL-8B-Thinking-Desktop-SFT | 8B | Desktop SFT checkpoint (thinking) |
| Qwen3-VL-8B-Thinking-Mobile-SFT | 8B | Mobile SFT checkpoint (thinking) |
| Qwen3-VL-8B-Thinking-UI-MOPD-Student | 8B | Final cross-platform student (thinking) |
