Qwen3-VL Technical Report (2511.21631v1)
Abstract: We introduce Qwen3-VL, the most capable vision-LLM in the Qwen series to date, achieving superior performance across a broad range of multimodal benchmarks. It natively supports interleaved contexts of up to 256K tokens, seamlessly integrating text, images, and video. The model family includes both dense (2B/4B/8B/32B) and mixture-of-experts (30B-A3B/235B-A22B) variants to accommodate diverse latency-quality trade-offs. Qwen3-VL delivers three core pillars: (i) markedly stronger pure-text understanding, surpassing comparable text-only backbones in several cases; (ii) robust long-context comprehension with a native 256K-token window for both text and interleaved multimodal inputs, enabling faithful retention, retrieval, and cross-referencing across long documents and videos; and (iii) advanced multimodal reasoning across single-image, multi-image, and video tasks, demonstrating leading performance on comprehensive evaluations such as MMMU and visual-math benchmarks (e.g., MathVista and MathVision). Architecturally, we introduce three key upgrades: (i) an enhanced interleaved-MRoPE for stronger spatial-temporal modeling across images and video; (ii) DeepStack integration, which effectively leverages multi-level ViT features to tighten vision-language alignment; and (iii) text-based time alignment for video, evolving from T-RoPE to explicit textual timestamp alignment for more precise temporal grounding. Under comparable token budgets and latency constraints, Qwen3-VL achieves superior performance in both dense and Mixture-of-Experts (MoE) architectures. We envision Qwen3-VL serving as a foundational engine for image-grounded reasoning, agentic decision-making, and multimodal code intelligence in real-world workflows.

Qwen3-VL: A State-of-the-Art Vision-LLM for Unified Multimodal Intelligence
Model Motivation and Positioning
Qwen3-VL sets a new standard within the Qwen model series, focusing on scalable, high-fidelity unified vision-language modeling spanning text, images, and video. Its core design aims are: (1) to deliver text language modeling parity or superiority relative to text-only LLMs; (2) robust handling of long-context, interleaved multimodal input up to 256K tokens; and (3) advanced multimodal reasoning, including STEM, document, spatial, and agentic tasks. These goals reflect an explicit recognition that next-generation LLMs must be evaluated simultaneously on unimodal and multimodal axes and must retain or even improve pure-text reasoning accuracy despite multimodal pretraining.
Figure 1: The Qwen3-VL model suite covers both dense and Mixture-of-Experts variants, supporting deployment across latency and quality trade-offs.
Architecture Details
The Qwen3-VL framework is a three-component stack:
- Vision Encoder: Centered on a SigLIP-2 backbone, further pre-trained with dynamic resolution input and 2D-RoPE/interpolated absolute embeddings for scalable resolution, supporting both the default SigLIP2-SO-400M and SigLIP2-Large variants based on LLM scale.
- MLP Vision-Language Merger: Compresses and aligns visual features to LLM hidden state via two-layer MLPs; multi-level merger modules allow for DeepStack-style mid-layer ViT features to be routed to corresponding LLM layers.
- LLM Backbone: Instantiated in dense (2B/4B/8B/32B) and MoE (30B-A3B, 235B-A22B) variants, the flagship at 235B/22B activated per token. Integration is natively interleaved; Qwen3-VL directly processes mixed sequences of images, video, and text within a token window of 256K.
Figure 2: Qwen3-VL integrates multi-level ViT features (via DeepStack), interleaved positional encoding, and text-based temporal alignment for video, enabling dynamic and rich multimodal sequence representation.
Major Architectural Innovations
- Interleaved-MRoPE: Departing from earlier chunked (t/h/w) variants, the proposed frequency allocation interleaves temporal, horizontal, and vertical components, mitigating axis-dependent spectral bias and supporting long-range video and dense spatial modeling.
- DeepStack Fusion: Multi-level ViT tokens are projected into the LLM’s first three layers, ensuring that both low-level and high-level visual semantics—crucial for fine-grained tasks—are systematically retained and aligned with language features.
- Text-based Timestamps for Video: Rather than absolute or RoPE-only time encoding, explicit timestamp tokens (including both second and HMS representations) are inserted into the sequence, providing direct, sparse but effective temporal supervision and facilitating precise grounding in long videos.
Data and Training Pipeline
Pretraining Strategy
Pretraining is staged:
- S0: Vision-language alignment (merger layers only) with 67B tokens, providing an initial semantic bridge without catastrophic interference in language modeling.
- S1: Full-model multimodal pretraining on ~1T tokens, with a mixed data schedule to maintain text proficiency.
- S2: Long-context adaptation at 32K tokens, with increased text fraction for supporting document- and video-level reasoning.
- S3: Ultra-long context (262K) specialization for rare applications needing extended sequential cross-modal memory.
Pretraining data exploits high-quality semantic filtering, deduplication, recaptioning, and clustering for both image-caption and interleaved doc/image data, with targeted augmentation in low-density visual embedding space. Qwen3-VL’s knowledge, OCR, spatial/3D, and agent datasets compose a comprehensive multimodal corpus with importance-based sampling, explicit chain-of-thought, and massive synthetic and pseudo-labeled augmentation.
Post-training
Instruction and agentic fine-tuning separates "non-thinking" and chain-of-thought "thinking" variants. Distillation leverages strong teacher models (text and multimodal) for student specialization across parameter scales. RL stages—SAPO for both text and multimodal reward—include both reasoning-centric and generalized reward schemes, with focused penalties for rare failure modes (e.g., language mixing, repetition). Tool-integrated RL and self-evolving agentic data generation round out the pipeline for agent workflows.
Empirical Results and Benchmarking
Multimodal and Pure-Text Evaluation
Qwen3-VL-235B-A22B achieves leading or state-of-the-art performance across VQA, multimodal reasoning (MathVista, MathVision, MMMU, etc.), document/OCR (DocVQA, OmniDocBench), 2D/3D grounding (RefCOCO, ARKitScenes), spatial understanding, multi-image comprehension, and video understanding (including challenging benchmarks such as VideoMME, LVBench, and MLVU). Strong, often best-in-class, results are maintained in both non-thinking (direct) and thinking (CoT reasoning) settings, including outperformance of competing multimodal and pure-text LLMs (Gemini-2.5-Pro, GPT-5, Claude Opus 4.1) in numerous tasks.
Figure 3: The multilingual OCR capabilities of Qwen3-VL extend to 39 languages, with over 70% accuracy in 32 languages—a significant advance in practical multilingual efficacy.
Notably, Qwen3-VL’s smallest variant (2B parameters) demonstrates robust performance across both language and multimodal benchmarks, supporting edge deployment. Post-training and strong-to-weak distillation are shown to enable efficient model scaling while preserving cross-modal and unimodal capabilities.
Long Context and Memory
The model’s native 256K context window allows for robust retention, retrieval, and cross-referencing across arbitrarily long documents and videos. The “Needle-in-a-Haystack” evaluation places evidence at arbitrary positions within hours-long sequences. Qwen3-VL-235B-A22B-Instruct achieves 100% retrieval/answer accuracy up to 30 minutes (256K tokens) and over 99% when extrapolated to ~2 hours (1M tokens, via YaRN positional scaling), representing a distinct leap over prior state-of-the-art for long-form video and document reasoning.
Figure 4: Across video durations and evidence placements, Qwen3-VL-235B-A22B retains high-accuracy at scale, demonstrating tractable token-memory and long sequence reasoning.
Multimodal Agent Capabilities
Qwen3-VL is evaluated on GUI understanding, function calling, online search, and real environment interaction (ScreenSpot, OSWorld, AndroidWorld, etc.), delivering state-of-the-art results on perception (UI grounding), planning, and autonomous control, including context-sensitive tool use and multi-turn agentic workflows.
Ablation Analyses
Model ablations confirm the significance of architectural choices:
- DeepStack yields measurable gains in fine-grained, mid-level visual tasks.
- Interleaved-MRoPE and timestamp encoding are critical for temporal and video tasks.
- Square-root loss reweighting balances text/multimodal strengths, outperforming naive sums.
Theoretical and Practical Implications
Qwen3-VL demonstrates that, with judicious architecture, data, and curriculum design, large-scale VLMs can match or exceed unimodal LLMs on text, while advancing leading-edge multimodal and video reasoning. This unification has consequences for both theoretical scaling laws—parity is achievable with dense or MoE mixtures and predictable via systematic distillation/finetuning—and practical applications where real-world tasks increasingly demand seamless integration across language, visual, spatial, and interactive modalities.
The native support for extremely long contexts not only unlocks new classes of applications (e.g., legal, scientific, or medical document reasoning, surveillance/video compliance, and multi-turn digital/robotic agents), but also exposes new research questions around efficient multimodal memory, sparse retrieval, and the integration of external tools and environments.
Conclusion
Qwen3-VL establishes a new upper bound for unified, high-capacity vision-language modeling. Its architecture—leveraging interleaved-MRoPE, DeepStack fusion, dynamic video timestamping, and both dense/MoE scaling—sets a new reference for practical and theoretical progress on the multimodal LLM frontier. The open-sourced model zoo, inclusive of lightweight edge solutions, is positioned to enable further advances in agentic decision-making, embodied AI, and multimodal code intelligence, with experimental results validating the core claim: multimodal scaling need not trade off text capability for vision; the two can be advanced together without compromise.

Overview of the Paper
This paper introduces Qwen3‑VL, a powerful AI model that can understand both language and visuals. That means it can read text, look at images, watch videos, and connect all of that information to answer questions, solve problems, and follow instructions. It’s built to handle very long inputs—like entire books or hour‑long videos—and still remember and reason across everything it saw.
Key Objectives and Questions
The paper focuses on three main goals:
- Can a model understand and use text as well as top text‑only models, even while learning from images and videos?
- Can it keep track of information in very long contexts (up to 256,000 “tokens,” which are like pieces of text or visual markers), and connect details across many pages or minutes?
- Can it reason well about visuals—like solving math problems using diagrams, understanding complex images, and following events in videos?
How They Built and Trained the Model
The researchers designed both the model’s “brain” and the training process to make language and vision work together smoothly.
Architecture Upgrades (explained in everyday terms)
- Interleaved MRoPE (positional encoding): Think of this like giving the model a sense of “where” and “when” each piece of information belongs. For images and video, you need to know horizontal (left‑right), vertical (up‑down), and time (frame order). Earlier methods were unbalanced, which hurt long‑video understanding. The new “interleaved” method spreads these signals evenly, so the model tracks space and time more reliably.
- DeepStack (multi‑level vision features): A vision encoder (like a “camera brain”) sees low‑level details (edges, colors) and high‑level concepts (objects, scenes). DeepStack passes features from several vision layers directly into matching language layers. It’s like feeding the LLM both the raw details and the big picture at the same time, so it aligns words with visuals more precisely.
- Text‑based timestamps for video: Instead of relying only on math‑based position signals, they insert clear text markers such as “<3.0 seconds>” before frames. This makes time in video more explicit and understandable, improving tasks like finding when an event happens.
- Balancing text and multimodal training: They adjust the “weight” of training examples using a square‑root rule. Think of it like turning knobs so neither text nor image/video training dominates. This keeps language skills strong while boosting visual reasoning.
- Dense and MoE versions: “Dense” models process everything with the same parameters. “Mixture of Experts (MoE)” models have many expert blocks but only a few are active per input, which can be faster for similar quality—like consulting the right specialist for each question.
Training Process (four stages)
The model learns in steps, like a school curriculum:
- Stage 0 (Alignment): Only the part that connects vision and language is trained, so the model learns how to map images/video to words cleanly.
- Stage 1 (Full Multimodal Pretraining, 8K tokens): Everything trains together on huge amounts of mixed data (text plus images and some video), so language and vision skills grow side by side.
- Stage 2 (Long‑Context Pretraining, 32K tokens): The model is trained to handle much longer inputs, with more long text, more video, and multi‑step tasks.
- Stage 3 (Ultra‑Long Context, 256K tokens): Final training to master very long inputs—think entire textbooks or hour‑long videos—while staying coherent and accurate.
Data They Used (high‑level overview)
They carefully assembled and cleaned many kinds of data, so the model can handle real‑world tasks:
- Image captions and interleaved text+image documents: High‑quality descriptions and long multimodal pages (like books and websites) to learn grounded understanding.
- Knowledge and entities: Data about animals, landmarks, food, devices, and more, with rich descriptions to improve recognition and reasoning.
- OCR and document parsing: Reading text inside pictures and PDFs, understanding layouts, tables, and diagrams across many languages.
- Grounding and counting: Finding objects with boxes or points and counting them—important for precise visual tasks.
- Spatial and 3D reasoning: Understanding relationships like “left of,” “behind,” and predicting object positions in 3D from a single image.
- Code: Text‑only coding and multimodal coding (like turning UI screenshots into HTML/CSS, or converting diagrams to markup).
- Video: Dense captions, time‑aware grounding, and balanced sampling to capture both short moments and long stories.
- STEM reasoning: Millions of math and science exercises, diagrams, and step‑by‑step solutions to strengthen problem‑solving.
- Agents and tools: Data for interacting with apps (GUIs), calling functions (like search), and planning multi‑step tasks.
Post‑Training (polishing the model)
After pretraining, they fine‑tune the model for real tasks:
- Supervised Fine‑Tuning (SFT): Teaching the model to follow instructions, including “thinking” versions that show their reasoning steps, and “non‑thinking” versions that go straight to answers.
- Distillation: A stronger teacher model guides a smaller student model, helping it learn good reasoning from text without hurting vision skills.
- Reinforcement Learning (RL): The model practices tasks where answers can be checked (like math or grounding), and gets feedback to improve accuracy and alignment to user preferences.
Main Findings and Why They Matter
- Stronger language skills: Qwen3‑VL often beats similar text‑only models on language tests, showing that adding vision doesn’t weaken reading or writing—it can even help.
- Leading visual reasoning: It performs very well on tough multimodal benchmarks involving images, diagrams, and videos, including math‑related visual tasks.
- Long‑context mastery: With a native 256K token window, it can ingest and recall information across very long documents and videos, keeping track of multiple references and cross‑links.
- Flexible sizes and speed: From smaller dense models to large MoE versions, you can choose a model that fits your speed and quality needs. The flagship MoE (235B total, ~22B active per token) leads on many tasks while managing latency.
Overall, under similar training budgets and speed limits, Qwen3‑VL outperforms other models in both text and multimodal work.
Implications and Potential Impact
Qwen3‑VL can be a strong foundation for many real‑world tools:
- Reading and summarizing long documents or textbooks, and understanding the figures inside them.
- Watching and analyzing long videos, finding events by time, and explaining what happens.
- Solving math and science problems that involve diagrams or multi‑step reasoning.
- Acting as an agent that understands app screens (GUIs), plans actions, and uses tools like web search.
- Bridging visuals and code, turning screenshots or diagrams into working markup or programs.
In simple terms: this model helps computers see, read, and think together—at scale. That makes smarter assistants possible for schoolwork, research, creative projects, and complex workflows where understanding both text and visuals—and doing it over long spans—really matters.
Knowledge Gaps
Below is a single, concrete list of the paper’s knowledge gaps, limitations, and open questions that remain unresolved and could guide future research.
- Interleaved MRoPE specifics and ablations: The paper claims improved long-video modeling with interleaved t/h/w frequency allocation but provides no formal specification (exact dimension allocations, frequency schedules) or ablations isolating its impact across image, multi-image, and video tasks—especially under ultra-long contexts.
- DeepStack design trade-offs: Details are missing on which ViT layers feed which LLM layers, the merger configurations per level, and the quantitative impact on latency, memory, and stability; no ablations vary the number/placement of injected layers or compare additive vs. concatenative fusion.
- KV-cache compatibility and inference cost: It is unclear how multi-layer visual token injection (DeepStack) affects KV caching, attention caching reuse, streaming, and 256K-window inference throughput; no measurements of memory footprint, latency, or batching efficiency are provided.
- Text-based timestamp tokens efficacy: The timestamp strategy adds tokens and claims better temporal grounding, but there is no analysis of overhead, accuracy under variable fps, dropped/duplicated frames, or robustness to non-uniform sampling; comparisons to alternative time encodings (e.g., learned temporal embeddings, discretized bins) are absent.
- Loss reweighting clarity: The “square-root-normalized per-token loss” lacks a formal definition, sensitivity analyses (to mixture proportions), and ablations showing its effect on text vs. multimodal performance and on catastrophic forgetting across stages.
- Long-context stability and retention: Despite a 256K window, there are no quantitative retention/faithfulness evaluations (e.g., needle-in-haystack, cross-referencing across interleaved image/video-text) nor training stability diagnostics (gradient norms, optimizer schedules, context-length curriculum effects).
- Compute, energy, and reproducibility: Training compute (FLOPs), hardware setup, optimizer/hyperparameters per stage, checkpointing/memory strategies, and energy/carbon costs are not reported, hindering reproducibility and scalability assessments.
- Data transparency and licensing: Large internal corpora and synthesized datasets (OCR, documents, GUI, video, STEM, 3D grounding) lack source/licensing disclosure, demographic/topic coverage statistics, and contamination checks against evaluation sets.
- Bias and fairness assessments: No auditing or evaluation is provided for demographic bias, domain imbalance, or regional bias in multimodal and text-only data mixtures, nor fairness across languages, scripts, and cultural contexts—especially beyond Chinese and English.
- Multilingual generalization: Apart from OCR in 29 additional languages, the extent of multilingual VL capabilities (VQA, grounding, document parsing, STEM) and cross-lingual transfer are not evaluated; language-specific performance and error analysis are missing.
- OCR quality and scope: The OCR pipeline relies on pseudo-labels without human annotation; there is no breakdown of accuracy across scripts (e.g., Arabic, Devanagari), curved/rotated text, low-light/motion blur, or complex layouts, nor standardized metrics (CER/WER by domain).
- Document parsing robustness: The unified QwenVL-HTML/Markdown framework lacks evaluations on real-world heterogeneity (multi-column reading order, forms, footnotes, equations, cross-page references) and fails to report layout fidelity metrics or error modes.
- Grounding metrics and normalized coordinates: Using coordinates scaled to [0,1000] promises robustness, but there is no calibration analysis across aspect ratios/resolutions, nor clear evaluation protocols for crowded scenes, occlusions, small objects, and point-vs-box agreement.
- 3D grounding from single view: The feasibility of predicting 9-DoF boxes from monocular images is asserted without reporting camera intrinsics handling, error metrics (e.g., 3D IoU, orientation error), sensitivity to noise, or cross-dataset generalization in the virtual camera space.
- Video modeling omissions: Audio is not mentioned; multimodal (audio–video–text) integration, ASR alignment, and audio-grounded reasoning remain unexplored; long-video summarization/retrieval metrics and genre-specific performance are not reported.
- STEM generalization and leakage: Heavy reliance on synthetic/programmatically generated diagrams and K–12/undergrad exercises raises questions about template overfitting, data leakage to benchmarks (MathVista, MathVision), and robustness to unconventional, noisy, or research-level problems.
- Chain-of-thought (CoT) side effects: While thinking variants are trained on long CoT, there is no analysis of verbosity control, hallucination rates in reasoning steps, or privacy risks (revealing training data) nor measures to avoid spurious long reasoning when unnecessary.
- Agentic GUI capabilities: Trajectories are partially synthetic and audited, but there is no online, executable evaluation showing success rates on unseen apps, robustness to UI changes, prompt-injection/image-injection attacks (e.g., malicious UI elements), or safety constraints (e.g., avoiding destructive actions).
- Function calling and search reliability: The function-calling trajectories use non-executable synthesized functions; there is no ground-truth verification of tool outputs, assessment of hallucinated tool responses, or paper of integrating real tool execution to improve faithfulness.
- Distillation interactions with VL: Strong-to-weak distillation is performed on text-only data; the paper does not evaluate whether this shifts or degrades vision–language alignment, nor provide ablations balancing text-only vs. VL distillation.
- Robustness to OOD and adversarial inputs: There is no evaluation under domain shifts (egocentric vs. cinematic), noise/blur/compression, adversarial images (patches, stickers, steganography), or video corruptions; defenses against image-/video-based jailbreaks are not discussed.
- Safety, privacy, and content moderation: Aside from filtering out “harmful or low-value categories,” there is no systematic safety alignment evaluation (toxicity, adult content in images, face/PII recognition risks), red-teaming results, or privacy safeguards for internal data.
- Mixture-of-experts (MoE) routing details: The MoE models’ expert routing, capacity, load-balancing losses, and failure cases (expert collapse, token imbalance) are not disclosed; latency/throughput under multimodal interleaving and KV-cache compatibility are unreported.
- Evaluation transparency: Claims of “leading performance” are not backed (in this text) by per-benchmark scores, baselines, statistical significance, or error analyses across text, image, multi-image, and video tasks under comparable token budgets/latencies.
- Deployment constraints at 256K: Practical inference constraints (GPU memory per batch, streaming/chunked attention support, sliding-window strategies, early-exit policies, batch-size limits) and cost–quality trade-offs across 2B–235B models are not quantified.
- Impact of dynamic-resolution vision encoding: The combination of 2D-RoPE and absolute position interpolation is introduced without stress tests on extreme resolutions/aspect ratios, heavy crops/zoom, or scaling failures; no ablations compare alternative interpolation strategies.
- Data curation feedback loops: Many datasets are generated or filtered using prior Qwen models; the paper does not analyze amplification of pre-existing biases, error propagation, or the effect of model-generated labels on downstream evaluation fairness and reliability.

Notes on Deployment Choices and Risk Mitigation
- Model variants and latency/quality trade-offs: smaller dense models (2B/4B/8B) suit edge or low-latency tasks; 32B/MoE variants fit high-stakes or complex reasoning with higher compute costs.
- Thinking vs. non-thinking variants: use “thinking” for complex, multi-step reasoning (STEM, planning) and non-thinking for efficiency in straightforward tasks.
- Tooling ecosystem: many applications depend on function-calling, search integration, RPA frameworks, and data governance pipelines.
- Reliability and safety: long-context processing and multimodal reasoning reduce chunking errors but do not eliminate hallucinations; human-in-the-loop review, calibration sets, and monitoring are essential.
- Data and domain adaptation: performance in specialized domains (clinical, industrial, legal) improves with domain-tuned data, evaluation harnesses, and alignment to regulatory standards.
