Qwen3 Coder 30B A3B Instruct — Hardware Requirements & GPU Compatibility

ChatCode

Qwen3 Coder 30B A3B Instruct is a code-specialized Mixture of Experts (MoE) model from Alibaba Cloud's Qwen 3 Coder series, with 30 billion total parameters and approximately 3 billion active parameters per forward pass. The MoE architecture allows it to deliver strong coding performance while keeping per-token compute costs low, making it faster at inference than comparably capable dense models. The model is instruction-tuned for programming assistance, code generation, debugging, and software engineering conversation. It requires VRAM proportional to its total 30B parameter count for loading weights, but benefits from efficient inference throughput due to its low active parameter count.
