Qwen

Happier supports Qwen as a local CLI-backed provider.

Qwen Code is an experimental integration. It works and people use it daily, but its surface is younger than Claude, Codex or OpenCode and is more likely to change. What it supports today is in Agent capabilities.

Requirements

Qwen CLI installed locally.
Binary available on PATH (or set HAPPIER_QWEN_PATH).

Install Qwen

Happier can install it for you:

happier install provider qwen
qwen --version

Or install manually (macOS / Linux):

curl -fsSL https://qwen-code-assets.oss-cn-hangzhou.aliyuncs.com/installation/install-qwen.sh | bash
qwen --version

Windows (Run as Administrator in CMD):

curl -fsSL -o %TEMP%\\install-qwen.bat https://qwen-code-assets.oss-cn-hangzhou.aliyuncs.com/installation/install-qwen.bat && %TEMP%\\install-qwen.bat
qwen --version

Local authentication in Happier

Qwen supports launching its native auth flow from:

Settings → AI & Agents → AI backends → Qwen Code

Happier opens Qwen and sends /auth for you.

Auth-status detection for Qwen is currently conservative, so Happier may still show Unknown even though the login flow is available.

For the shared user guide, see Provider authentication.

Notes

Resume availability is session-specific in Happier and depends on valid resume metadata plus the current backend/settings.
Model, mode, and permission behavior can still vary by installed Qwen runtime.
Tool calls are normalized to canonical Happier tool renderers.

Troubleshooting

If Qwen is not detected:

Verify qwen --version works.
Restart Happier.
Set HAPPIER_QWEN_PATH if needed.
