Which Qwen 3 model should you choose? Complete comparison of the 235B, 32B, 30B, 14B, 8B and 4B versions
Launched in 2025 by Alibaba Cloud, the Qwen 3 series has become one of the most complete families of open-source AI models on the market (or more precisely, open-weight models). From the ultra-light Qwen3-1.7B designed for modest PCs to the computing powerhouse Qwen3-235B-A22B, each version fits a specific use case: research, development, local inference, or large-scale cloud deployment.
But which Qwen 3 model should you pick based on your hardware and workflow? Should you go for the Dense Qwen3-32B, known for its accuracy, or the Mixture-of-Experts Qwen3-30B-A3B, praised for its speed and lower VRAM usage? And how do the mid-range options like Qwen3-14B and Qwen3-8B perform, often underestimated yet ideal for local inference on 16 GB GPUs?
The Qwen 3 project represents more than a technical evolution. It reshapes the hierarchy of open-weight large language models. Each version offers an extended context window (up to 128K tokens or even 1 million, according to the QwenLM report) and supports 119 languages, from French and English to Chinese and Arabic.
This guide reviews the 235B, 32B, 30B, 14B, 8B and 4B models, comparing their reasoning performance, VRAM footprint and ideal use cases. The goal is to help you choose the best Qwen 3 model for your setup, whether you’re running an RTX 5090, a laptop, or an AI server.
Overview of the Qwen 3 family: Dense, MoE and Thinking Mode
The Qwen 3 lineup uses a flexible architecture designed to scale from laptops to GPU clusters. The idea is simple: deliver a model optimized for every environment without sacrificing reasoning quality or inference speed.
According to the official QwenLM blog, the family is split into two main categories, the Dense models and the Mixture-of-Experts (MoE) models, plus one major innovation introduced with this generation, the Thinking Mode.
The two main architectures
Dense models, such as Qwen3-32B or Qwen3-14B, follow a traditional architecture where all parameters are activated at each computation step. This ensures maximum stability and high precision for complex reasoning tasks like mathematics, coding or logical analysis. The trade-off is higher VRAM usage and slightly slower token generation.
MoE (Mixture-of-Experts) models, such as Qwen3-30B-A3B or Qwen3-235B-A22B, take a smarter approach: only a few “experts” are activated per token, reducing memory load and boosting throughput. This structure enables models to generate tokens up to 4-6 times faster than dense models of similar size, with only a minor quality drop in typical tasks.
The Thinking Mode
Another major improvement is the Thinking Mode. Built directly into Qwen 3 (not limited to QwQ), it activates a step-by-step reasoning process similar to chain-of-thought. The model can “think” before answering, improving accuracy on complex or multi-step questions. You can toggle it with the /think and /no_think commands, as mentioned on Hugging Face’s Qwen3-32B page.
The Thinking Mode is particularly useful for:
- advanced coding and code planning,
- mathematical or logical problems,
- autonomous AI agents, where reliable reasoning is essential.
Context windows and compatibility
One of the strongest advantages of the Qwen 3 series is its large context window. All models handle at least 128 K tokens, with some extending to 256 K or even 1 million tokens using RoPE scaling and YaRN extension techniques. This makes Qwen 3 a credible alternative to proprietary models such as GPT-4 Turbo for RAG (Retrieval-Augmented Generation) and large-scale document analysis.
In practice, effective context length depends on both model and hardware. A Qwen3-30B-A3B quantized at 4-bit can handle extended contexts on an RTX 5090 (32 GB), while a Qwen3-8B runs more comfortably with a 64 K token window.
Quick comparison of Qwen 3 models
The Qwen 3 family covers a wide range of models, from the 0.6B built for mobile and IoT devices to the massive 235B designed for cloud-scale AI research. Each version aims for a specific balance between speed, accuracy and memory consumption.
The table below summarizes the core specifications to help you quickly visualize the main differences between Dense and Mixture-of-Experts (MoE) architectures.

| Qwen3-4B | Dense | 4 B | 4 B | 5 GB | 128 K | Edge devices, lightweight servers |
| Qwen3-1.7B | Dense | 1.7 B | 1.7 B | 3 GB | 128 K | Mobile or CPU-only offline AI |
| Qwen3-0.6B | Dense | 0.6 B | 0.6 B | 2 GB | 128 K | IoT, embedded automation tools |
Key takeaways from the comparison
- MoE models (30B-A3B and 235B-A22B) deliver unmatched efficiency, since only a few experts are activated per token.
- Dense models, such as Qwen3-32B or 14B, remain the most accurate for logic-heavy or analytical workloads.
- Mid-range models (14B and 8B) provide the best performance-to-accessibility ratio, ideal for 16 GB GPUs.
- Light models (4B, 1.7B) ensure low latency and easy deployment for portable or embedded setups.
According to RunPod and LLM-Stats, the Qwen3-30B-A3B remains the best overall compromise for local inference on 32 GB GPUs. It often outperforms the 32B Dense model in speed while staying lighter to load.
Qwen3-235B-A22B: the flagship model
The Qwen3-235B-A22B represents the top tier of the Qwen lineup. Developed by Alibaba Cloud, it embodies the project’s goal to provide an open-weight LLM rivaling proprietary systems like GPT-4 or Gemini 1.5 Ultra.
This model uses a Mixture-of-Experts (MoE) structure: out of 235 billion total parameters, only 22 billion are active per token. This approach drastically reduces GPU requirements while maintaining deep reasoning and exceptional linguistic consistency. According to the QwenLM blog, each forward pass activates 8 experts out of 128, balancing diversity and performance.
Capabilities and performance
- Context window: 256 K tokens by default, extendable to 1 million using YaRN and RoPE scaling (Qwen3 arXiv report).
- Languages supported: 119 languages and dialects, including English, French, Chinese, Arabic and Spanish.
- Performance: over 90% scores on AIME 2025, LiveBench Math and Arena Hard benchmarks, according to LLM-Stats.
- Use cases: fine-tuning for research, distributed inference, large-scale RAG, multimodal analysis with Qwen3-VL.

Qwen3-32B vs Qwen3-30B-A3B: the key comparison
This is where the real dilemma lies for most users. Both the Qwen3-32B (Dense) and the Qwen3-30B-A3B (MoE) are the most popular choices for local inference on high-end GPUs. They deliver an excellent balance of reasoning power, efficiency and VRAM usage, but follow very different architectural philosophies.
Performance and speed
Community benchmarks clearly show a speed advantage for the 30B-A3B. Based on tests shared on Reddit /r/LocalLLaMA, the model reaches up to 190 tokens/s on an RTX 5090 in Q4_K_M quantization with an 8K context. By comparison, the 32B Dense usually stays around 50–60 tokens/s under similar conditions. There is currently no data available for the new NVFP4 format, yet these models are already listed on Hugging Face in the optimized NVFP4 version.
This difference comes from the Mixture-of-Experts mechanism: only a few experts are activated per token, which drastically lowers GPU load. During long conversations or multi-turn chat sessions, the Qwen3-30B-A3B maintains low latency and strong contextual coherence.
According to Kaitchup Substack, this model can be up to 6× faster in certain generation scenarios with equivalent batch sizes, while keeping dense-like accuracy across general benchmarks.
VRAM usage and efficiency
The Qwen3-30B-A3B is notably lighter:
- around 19 GB VRAM in INT4,
- versus 27 GB for the Qwen3-32B Dense, according to Unsloth.
This makes it possible for most users with RTX 4090 or 5090 (32 GB) cards to run the model entirely in GPU memory without CPU offload, leaving headroom for large context windows up to 128 K tokens.
Precision and behavior
On logical and mathematical benchmarks such as AIME, Arena Hard and LiveBench, the Qwen3-32B Dense still holds a slight accuracy edge. It produces fewer arithmetic mistakes and fewer hallucinations in long-form reasoning. It remains the top choice for:
- scientific or analytical tasks,
- advanced code validation,
- or agent-based computation chains.
The 30B-A3B, however, excels in conversational, creative and generative use cases. Its fluidity and speed make it ideal for text generation, RAG applications, or local AI assistants.
Summary

How to choose the right Qwen 3 model
Choosing the right Qwen 3 model depends on your hardware, your use case, and the level of precision you need. All models share the same core architecture, but their behavior varies greatly depending on VRAM capacity, context length, and task complexity. Here are the key selection factors to consider.
1. Available VRAM capacity
GPU memory is the first constraint to check. Dense models require more VRAM since all parameters are active, while MoE models activate only a fraction of experts. According to RunPod and Unsloth:
- Qwen3-30B-A3B (MoE) → ~19 GB (Q4)
- Qwen3-32B (Dense) → ~27 GB (Q4)
- Qwen3-14B → ~12 GB
- Qwen3-8B → ~8 GB
- Qwen3-4B → ~5 GB
👉 Tip: Always keep at least 2–4 GB of free VRAM on your GPU to avoid swap delays and KV cache slowdowns.
2. Desired generation speed
Token generation speed depends directly on model type, quantization, and batch size. MoE models like 30B-A3B are typically 4–6× faster than their dense equivalents, according to Kaitchup Substack. If you want a responsive model for coding, chat, or interactive tasks, go for:
- Qwen3-30B-A3B for GPUs ≥ 24 GB,
- or Qwen3-8B / 14B for GPUs ≤ 16 GB.
For long-running tasks like document analysis, RAG, or structured text generation, dense models provide more consistent output even if they’re slower.
3. Required reasoning precision
Benchmarks consistently show:
- Qwen3-32B tops AIME, Arena Hard, and LiveBench Math,
- Qwen3-30B-A3B performs close in conversational and general-purpose contexts,
- Qwen3-14B and 8B remain reliable for writing, code generation, and support chat.
👉 For analytical or technical AI assistants, choose 32B Dense. For versatile local AI agents, 30B-A3B is more efficient.
4. Context window size
All Qwen 3 models support at least 128 K tokens, and some like 235B-A22B and 30B-A3B extend up to 256 K or even 1M tokens using YaRN or RoPE scaling (QwenLM arXiv report). If your workflow involves long documents, PDFs, or source code, pick a model with an extended context window. For most everyday tasks, 128 K is more than enough.
5. Execution environment
| Environment | Recommended model | Why it fits well |
|---|---|---|
| High-end PC (RTX 5090, 32 GB) | Qwen3-30B-A3B | Fast, smooth, excellent VRAM/perf ratio |
| Pro workstation (RTX 4090, 24 GB) | Qwen3-14B or 30B-A3B (Q4) | Balanced between precision and efficiency |
| Mid-range PC (RTX 4070 / 4070 Ti) | Qwen3-8B | Stable, lightweight, full multilingual support |
| Laptop AI / GPU 8 GB | Qwen3-4B | Instant startup, low latency |
| Cloud / multi-GPU cluster | Qwen3-235B-A22B | Maximum power and reasoning depth |
| Edge / IoT / ARM CPU | Qwen3-1.7B or 0.6B | Minimal power usage, offline AI capability |
In short, the best Qwen 3 model is the one that balances power, speed, and VRAM usage for your hardware. 32 GB GPUs fully unlock the 30B-A3B, while mid-range setups are best served by 14B or 8B. Ultra-light models (4B, 1.7B, 0.6B) are perfect for embedded or offline AI applications.
