Qwen3-30B-A3B is Alibaba's efficient MoE model released in April 2025, with 30.5 billion total parameters and only 3.3 billion activated per token through 128 experts (8 selected). This sparse design delivers low inference cost while keeping broad capability across reasoning, coding, and general tasks. The model supports switching between a step-by-step reasoning mode for complex problems and direct generation for straightforward queries within a single architecture. Native context covers around 40K tokens, extending to 131K via YaRN, and it handles mathematical reasoning, code generation, and instruction following across 100+ languages, drawing on roughly 36 trillion tokens of pretraining data. Both thinking and non-thinking modes let users match computational depth to task complexity. MoE sparse activation means the inference cost reflects only a fraction of the full 30.5 billion parameters. Open-weight under Apache 2.0.
