Qwen3 Coder 480B A35B Instruct

Qwen3-Coder-480B-A35B-Instruct, released in 2025, is a frontier coding-focused large language model developed by Alibaba as part of the Qwen3 series. It employs a Mixture-of-Experts architecture with 480 billion total parameters and 35 billion activated per inference, balancing immense scale with efficiency through sparsity. The model specializes in agentic software engineering workflows, including large-scale code refactoring, debugging, feature development, and legacy system modernization. It also delivers state-of-the-art performance across Agentic Coding, Browser-Use, and Tool-Use tasks, achieving results competitive with proprietary frontier models like Claude Sonnet. With advanced reasoning and automation capabilities, Qwen3-Coder-480B-A35B-Instruct establishes itself as one of the most powerful open coding models available.
