Alibaba's coding-tuned agent

Source: https://www.agentclash.dev/try/qwen3-coder
Markdown export: https://www.agentclash.dev/md/try/qwen3-coder
Session limit: 10 minutes

A page visit does not create a sandbox. Starting a disposable session requires an explicit action on the HTML page.

## Suggested commands

- **Start Qwen Code**: `qwen`
- **Version**: `qwen --version`
- **Make a file to work on**: `echo 'def add(a, b): return a + b' > math.py && cat math.py`

## Authentication

Free trial runs Qwen3 Coder via Qwen Code on AgentClash credentials — no key needed. To use your own, set OPENAI_BASE_URL/OPENAI_API_KEY or run qwen and sign in.

1. Free trial: just run `qwen` (preconfigured for Qwen3 Coder)
2. Your own key: export OPENAI_API_KEY + OPENAI_BASE_URL, then run qwen
