1. One-Click Hermes Agent Installation on Windows
Deploying Hermes Agent on Windows has been massively simplified — the official automated scripts make it very easy. For beginners, this is also the best practice this Hermes installation tutorial recommends.
Steps:
- Open PowerShell on Windows. (⚠️ Strongly recommended: right-click the icon and choose "Run as administrator" to avoid permission errors later in the installation).
- In the terminal window, copy and run the one-click install command:

This may take a few minutes depending on your network; keep the connection stable and be patient.
2. Hermes Agent Initial Setup Wizard (Including Model Connection)
Once all dependencies are installed, the terminal configuration wizard for Hermes Agent starts automatically. Beginners should use the up/down arrow keys to select the first option, Quick setup, and continue.
2.1 Configure the AI Model Provider (Using Minimax as an Example)
As a powerful AI agent, Hermes needs an LLM to drive it. Choose the provider that matches the API Key you have. For users in China, this installation tutorial demonstrates with the excellent domestic Minimax model:
- In the provider list shown in the terminal, find and select the matching AI model platform.
- Following the on-screen prompts, safely enter your API Key to complete authentication.
2.2 Message Platform Integration (Skip Feishu Configuration)
Hermes Agent natively supports connecting to various third-party messaging apps for interaction. However, the default wizard list doesn't yet offer a direct option for China's commonly used "Feishu" (Lark) platform.
Recommendation: select Skip at this step. If you later need to connect the agent to Feishu, you can fully configure it separately through the Gateway.
For the remaining automated configuration steps, just type Y (Yes) and press Enter whenever prompted to confirm.
When you see this iconic welcome screen in the terminal, congratulations — Hermes Agent's core installation and basic configuration are complete!
3. Hermes Pitfall Guide: Fixing the "Model Not Recognized" Error
Many users who follow other Hermes installation tutorials get stuck on a classic environment bug: the configured model isn't recognized or loaded correctly. The status bar or terminal will typically show an empty model or throw an error (as shown below).
This is most likely related to delayed environment-variable reads or path configuration in Windows.
✅ Exclusive fix:
No need to uninstall and reinstall! The fix is straightforward: in the Hermes Agent chat box or terminal input line, use the built-in /model command to manually re-specify the model name.
Once executed, if the terminal correctly echoes the model name you configured, the model is mounted successfully. Now you can enjoy your very own Hermes Agent without any hiccups!
