Qwen Code

Alibaba Qwen · · Agent

Alibaba open-sourced Qwen Code alongside Qwen3-Coder: an Apache-2.0 terminal coding agent adapted from Google's Gemini CLI, with the prompts and parser reworked for the Qwen3-Coder function-call format.

Why it matters

The first frontier-lab harness that was a fork of another frontier lab's harness. Google had released Gemini CLI open-source four weeks earlier; Alibaba took it, retargeted it at its own model and shipped it the same day as the model — which is the moment the open terminal agent became shared infrastructure rather than each lab's own product.

This is LLM World's historical reading, not a claim by Alibaba Qwen. The facts above and the sources below are what it rests on.

Qwen's own blog post announcing Qwen3-Coder introduces Qwen Code in the same post and carries the dateline 'July 22, 2025 · 5 min · 1000 words · Qwen Team'. NOTE A DISAGREEMENT: Alibaba Cloud's own press room and most English coverage date the same launch to 23 July 2025 — plausibly a UTC-versus-China-time or an embargo-versus-blog split. Both are Alibaba pages. 22 July is recorded because it is the date on the technical announcement that actually introduces Qwen Code; a reader comparing against the press release will see one day's offset. The GitHub repository was created 26 June 2025 and its first tagged release is v0.0.2 on 1 August 2025, so neither was used.
