Qwen3 30B A3B is Alibaba's Mixture-of-Experts model with 30.5B total parameters and 3.3B activated per token, featuring hybrid thinking/non-thinking modes, 128 experts with 8 active, and 119-language support.
Capabilities, design details, and architectural traits
Qwen3 30B A3B is a Mixture-of-Experts large language model from the Qwen3 family designed to balance high performance with efficient inference. It has 30.5 billion total parameters with 3.3 billion active per forward pass.
Qwen3 30B A3B's MoE design and dual reasoning modes distinguish it from dense models:
| Distinctive Trait | Why It Matters | How It Works |
|---|---|---|
| 3.3B activated parameters | Efficient inference without performance loss | Uses 8 experts out of 128 total during inference, activating only 3.3B of 30.5B total per token |
| Hybrid reasoning modes | Complex tasks need step-by-step thinking, simple queries need speed | Supports both thinking mode for deep reasoning and non-thinking mode via /no_think for rapid responses |
| 128-expert pool | Broader knowledge coverage with selective activation | Selects 8 optimal experts from 128 pool for each forward pass based on input context |
| 131K token context with YaRN | Long documents and massive datasets require extended context | Native 32K context extended to 131,072 tokens using YaRN rope scaling method |
| Strong-to-weak distillation | Competitive performance from smaller model | Trained via distillation from larger Qwen3 models, maintaining reasoning and coding quality with fewer activated parameters |
Qwen3 30B A3B was built to deliver competitive performance on reasoning, coding, and multilingual benchmarks while using significantly fewer activated parameters than previous models. It outperforms QwQ-32B with 10 times fewer activated parameters.
The model is optimized for conversational AI, code assistance, agentic systems, search, multimedia, and enterprise RAG. It supports over 100 languages for multilingual instruction and translation tasks.
