qwen3-zjuidg is a fine-tuned vision-language model based on Qwen/Qwen3-VL-4B-Instruct.
It is adapted for GUI understanding and cross-app mobile task reasoning, with a focus on structured action prediction in mobile interaction scenarios.
Model Description
This model is fine-tuned for mobile GUI agent tasks.
Given a user instruction, current screenshot, and task-related context, the model is designed to generate structured outputs such as:
explanation of the current step
compressed task summary
long-memory style key information
action prediction for the next interaction step
The model is intended for research and experimentation in:
mobile GUI understanding
cross-app task completion
multimodal reasoning
agent policy modeling
long-context interaction modeling
Base Model
Base model: Qwen/Qwen3-VL-4B-Instruct
Fine-tuned from the original Qwen3-VL checkpoint for GUI-agent related tasks
Qwen3-VL-4B-Instruct
Meet Qwen3-VL — the most powerful vision-language model in the Qwen series to date.
This generation delivers comprehensive upgrades across the board: superior text understanding & generation, deeper visual perception & reasoning, extended context length, enhanced spatial and video dynamics comprehension, and stronger agent interaction capabilities.
Available in Dense and MoE architectures that scale from edge to cloud, with Instruct and reasoning‑enhanced Thinking editions for flexible, on‑demand deployment.
Visual Coding Boost: Generates Draw.io/HTML/CSS/JS from images/videos.
Advanced Spatial Perception: Judges object positions, viewpoints, and occlusions; provides stronger 2D grounding and enables 3D grounding for spatial reasoning and embodied AI.
Long Context & Video Understanding: Native 256K context, expandable to 1M; handles books and hours-long video with full recall and second-level indexing.
Enhanced Multimodal Reasoning: Excels in STEM/Math—causal analysis and logical, evidence-based answers.
Upgraded Visual Recognition: Broader, higher-quality pretraining is able to “recognize everything”—celebrities, anime, products, landmarks, flora/fauna, etc.
Expanded OCR: Supports 32 languages (up from 19); robust in low light, blur, and tilt; better with rare/ancient characters and jargon; improved long-document structure parsing.
Text Understanding on par with pure LLMs: Seamless text–vision fusion for lossless, unified comprehension.
Model Architecture Updates:
Interleaved-MRoPE: Full‑frequency allocation over time, width, and height via robust positional embeddings, enhancing long‑horizon video reasoning.
DeepStack: Fuses multi‑level ViT features to capture fine‑grained details and sharpen image–text alignment.
Text–Timestamp Alignment: Moves beyond T‑RoPE to precise, timestamp‑grounded event localization for stronger video temporal modeling.
This is the weight repository for Qwen3-VL-4B-Instruct.
