Switch Provider to Gateway.

6. Fill Base URL / API Key / Auth scheme / Models

• Base URL: use a Claude-compatible address such as https://api.qiuqiutoken.com. Do not manually append /v1.
• API Key: paste your token.
• Auth scheme: choose auto, bearer, or x-api-key according to your address and key.

• A simple message such as hello returns normally.

• The app does not repeatedly return to the default login flow.

FAQ

• Menu cannot be opened: click the email input, press Tab to focus the top-left menu, then press Enter.
• Already logged in by mistake: reopen third-party inference configuration and run Apply locally again.
• It still uses the default service after restart: confirm Provider is still Gateway and Apply locally was clicked before restart.
