Qwen3-VL-8B-Thinking-Mobile-SFT

This is the Mobile SFT model from the UI-MOPD project — a supervised fine-tuned 8B model trained on mobile GUI interaction data, serving as the initialization for the student policy before on-policy distillation.

Model Description

Qwen3-VL-8B-Thinking-Mobile-SFT is fine-tuned from Qwen3-VL-8B-Thinking on mobile interaction trajectories from the Uni-GUI dataset. It provides a warm-start checkpoint for the 8B student model in the UI-MOPD multi-teacher on-policy distillation framework.

Key Highlights

Base Model: Qwen3-VL-8B-Thinking
Training Data: Mobile subset of Uni-GUI (~160K interaction steps across ~11.5K trajectories)
Training: Supervised fine-tuning (SFT) on mobile GUI interaction trajectories
Role: Warm-start initialization for the student policy in Stage 2 (RL distillation)

Training Details

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

Stage 1 (This Model): Supervised fine-tuning of Qwen3-VL-8B-Thinking on mobile GUI interaction trajectories from Uni-GUI.
Stage 2: The SFT checkpoint is further trained via DAPO (reinforcement learning) with multi-teacher on-policy distillation using platform-conditioned routing from 32B teacher models.

Intended Use

This model is designed to:

Serve as a warm-start checkpoint for the student policy in the UI-MOPD distillation framework
Be used as a standalone mobile GUI agent for executing mobile tasks (e.g., app navigation, settings control, messaging)
Provide a baseline for comparing SFT-only vs. distillation-enhanced performance

How to Use

from transformers import Qwen3VLForConditionalGeneration, AutoProcessor

model = Qwen3VLForConditionalGeneration.from_pretrained(
    "UI-MOPD/Qwen3-VL-8B-Thinking-Mobile-SFT",
    torch_dtype="auto",
    device_map="auto",
)
processor = AutoProcessor.from_pretrained("UI-MOPD/Qwen3-VL-8B-Thinking-Mobile-SFT")
