Manage your Yuanliu account, groups, and models in DSH.
Before you start
- Install the latest version of DeepSeek Harness; see the official download page.
- Have a 元流 account with sufficient balance, an existing valid API key and an available model group. Register an account if needed.
- Usage is billed by the platform. Agent tasks may make multiple requests; start with a low-cost model and a small task.
Install the plugin
- Open the plugin page. Under Installation & versions, copy the current installation content. Do not copy a version URL from a screenshot.
- In Harness, open Plugins → Add plugin.
- Paste the address into Package name or address, choose Install, then follow any prompt to enable the plugin or restart Harness.
Sign in and select models
- Open Settings → 元流 Models and sign in with your platform email and password.
- Select the models you want and choose Save changes. The plugin uses existing group keys; it does not create API keys.
- Return to chat and select an enabled model from the model picker.
Screenshots show the Chinese interface. Brand names, installation addresses and versions shown are examples only; use the current installation address supplied by your plugin distributor.
Try your first task
Open a small project folder, select an enabled model, and send:
Check this project’s startup instructions against its configuration. Only update documentation; do not change code or dependencies. List the changes and what you verified.
Review the file changes, diff and terminal output before accepting the result. Back up important files or use Git first. The plugin supplies models; it does not include Office or Blender integrations.
Everyday use
- Refresh catalog reloads groups and models after platform changes, keeping unsaved edits. Select models and save again to apply them. New models start disabled.
- The account bar shows balance; its refresh icon updates only the balance. Use Account settings to sign out or sign in again.
- Select a group to change its name, enabled state or protocol. Use a model’s settings to adjust its name, context, output limit and capabilities. Context is shared by input and output; raising the output limit does not enlarge it.
- Manually configured providers remain in Harness’s Models settings.
- The settings page follows Harness’s language. This guide is also available in 简体中文.
Troubleshooting
No models, or an invalid API key? Confirm that your platform account has a valid key, an available group and sufficient balance. Refresh the catalog, enable the desired models and save. If the session has expired, sign in again in Account settings.
Will the password be saved? Remember password is off by default. The login session is saved through DSH’s credential service for session restoration. Remembered passwords use system-protected encryption, with no plaintext fallback; Linux requires an unlocked Secret Service and secret-tool. Signing out removes this plugin’s saved credentials while retaining local model preferences.
After an upgrade? Older manual provider entries are preserved. If names conflict, check and back up the entries before removing obsolete ones in Harness’s Models settings.
