Alibaba Open-Sources Qwen3-Coder: A 480B Parameter Code Model

Alibaba has released Qwen3-Coder, a powerful 480B-parameter code model achieving state-of-the-art results in agentic coding tasks. Supporting a native context length of 256K tokens (extensible to 1M), Qwen3-Coder excels in coding and intelligent tasks. Alongside the model, they've open-sourced Qwen Code, a command-line tool designed for seamless integration. Extensive use of large-scale reinforcement learning significantly improved code execution success rates and complex problem-solving capabilities.
