Qwen3-VL-32B-Thinking-Mobile-Teacher

Qwen3-VL-32B-Thinking-Mobile-Teacher

This is the Mobile Teacher model from the UI-MOPD project — a platform-specific expert trained for mobile GUI interaction tasks.

Model Description

Qwen3-VL-32B-Thinking-Mobile-Teacher is fine-tuned from Qwen3-VL-32B-Thinking on mobile interaction trajectories from the Uni-GUI dataset. It serves as the mobile-platform teacher in the UI-MOPD multi-teacher on-policy distillation framework.

Key Highlights

• Base Model: Qwen3-VL-32B-Thinking
• Training Data: Mobile subset of Uni-GUI (~160K interaction steps across ~11.5K trajectories)
• Role: Platform-specific teacher for mobile environments in the UI-MOPD distillation pipeline
• MobileWorld Performance: 16.2% task success rate (vs. 9.4% base model)

Training Details

This model is obtained in Stage 1 of the UI-MOPD training pipeline:

1. Stage 1 (This Model): Supervised fine-tuning of Qwen3-VL-32B-Thinking on mobile GUI interaction trajectories from Uni-GUI to produce a platform-specific mobile expert.
2. Stage 2: The mobile teacher (this model) and a desktop teacher jointly guide a shared 8B student policy via multi-teacher on-policy distillation with platform-conditioned routing.

Performance

Intended Use

This model is designed to:

• Serve as a teacher model in the UI-MOPD distillation framework for training cross-platform GUI agents
• Be used as a standalone mobile GUI agent for executing mobile tasks (e.g., app navigation, settings control, messaging)

How to Use

from transformers import Qwen3VLForConditionalGeneration, AutoProcessor

model = Qwen3VLForConditionalGeneration.from_pretrained(
    "UI-MOPD/Qwen3-VL-32B-Thinking-Mobile-Teacher",
    torch_dtype="auto",
    device_map="auto",
)
processor = AutoProcessor.from_pretrained("UI-MOPD/Qwen3-VL-32B-Thinking-Mobile-Teacher")
