Jin10 data reported on July 23, that in the early morning, Tongyi Qianwen officially released Qwen3-Coder, which is its most capable code model to date. Tongyi Qianwen states that Qwen3-Coder is available in multiple sizes, but we are eager to provide everyone with the current most powerful version, Qwen3-Coder-480B-A35B-Instruct. This is a 480B parameter model activating 35B parameters, natively supporting a 256K token context and can be expanded to 1M tokens via YaRN, with outstanding coding and agent capabilities. Qwen3-Coder-480B-A35B-Instruct has achieved SOTA results of open-source models in Agentic Coding, Agentic Browser-Use, and Agentic Tool-Use, and can compete with ClaudeSonnet4.
