Qwen3-Next-80B-A3B Instruct

Qwen3-Next-80B-A3B Instruct is a highly efficient instruction-tuned large language model designed for fast, stable responses with ultra-long context handling and high throughput. It activates only a small portion of its 80 billion parameters to achieve significant improvements in speed and cost-efficiency without sacrificing performance in reasoning, code generation, and other complex tasks.

Technical Specifications

Qwen3-Next-80B-A3B Instruct activates only about 3 billion parameters out of 80 billion during inference, making it much faster and cheaper to run — about 10 times faster and more cost-efficient compared to the earlier Qwen3-32B model. It delivers over 10 times higher throughput on long contexts of 32K tokens or more. The model supports flexible deployment options including serverless, on-demand dedicated, and monthly reserved hosting. It is compatible with SGLang and vLLM for deployment with advanced mult-token prediction capabilities, ensuring efficient and scalable usage.
