Qwen3-VL: Alibaba’s Flagship Multimodal Foundation Model
Qwen3-VL is Alibaba’s most advanced multimodal model, designed for unified understanding and reasoning across:
- Text
- Images
- PDFs
- Tables
- Graphical User Interfaces (GUI)
- Videos
It features a native 256K context window, enabling:
- Stable handling of documents spanning hundreds of pages.
- Whole-textbook comprehension.
- Processing of long videos with accurate localization and citation.
This results in a full-stack multimodal engine tailored for enterprise-grade scenarios.

Model Configurations
- Dense models: 2B / 4B / 8B / 32B
- Mixture of Experts (MoE): 30B-A3B / 235B-A22B
Benefits: Flexible trade-offs between latency, throughput, and accuracy.
> Note: Multimodal training enhances — rather than reduces — language capabilities, outperforming pure‑text LLMs on multiple NLP benchmarks.

Key Technical Upgrades
1. Interleaved-MRoPE
- Mixes temporal, horizontal, and vertical frequency signals.
- Resolves legacy MRoPE frequency bias in long video sequences.
- Enables more stable spatiotemporal modeling.
2. DeepStack Visual Cross-Layer Injection
- Extracts multi-level features from the visual encoder.
- Injects features into corresponding LLM layers.
- Fuses low-level details with high‑level semantics for improved visual reasoning accuracy.
3. Text-Based Timestamps
- Uses explicit tokens like `<3.0 seconds>` instead of complex encodings.
- Improves control and generalization for long video temporal understanding.

Training Methodology
- Four-stage pretraining: 8K → 32K → 256K
- Supervised Fine-Tuning (SFT)
- Strong-to-weak distillation
- Reinforcement Learning (RL) for both Reasoning and General modes
- Dual modes: Thinking / Non-Thinking to balance speed and reasoning depth
---
Multimodal Data Sources
- High-quality image-text pairs
- Web pages and textbooks
- Structured PDF parsing (HTML/Markdown)
- OCR in 39 languages
- 3D and spatial data understanding
- Action/event-level video semantics
- Cross-layer grounding datasets
- 60M+ STEM problems
- GUI and multi-tool Agent behavioral data
