Customer service is undergoing a revolution, and OpenAI is at the forefront with its Customer Service Agents Demo—a sleek and modular example of AI-powered support built using the new OpenAI Agents SDK.

This open-source project offers a glimpse into how you can create custom AI agents to handle customer queries in real-time—complete with a Python backend, a modern Next.js frontend, and an orchestration engine designed to make intelligent decisions.

In this blog post, we’ll explore the architecture, features, and most importantly—how to run it on your own Windows VPS.

🧠 What is the Customer Service Agents Demo?

OpenAI’s Customer Service Agents Demo showcases how developers can integrate AI agents into customer support workflows.

What's inside?

• 🧩 Python Backend: Uses the new OpenAI Agents SDK to orchestrate responses and tools.

• 🖥️ Next.js UI: A real-time chat interface with a visualization of the agent’s internal decision-making process.

• 📦 MIT Licensed: You're free to modify, deploy, and commercialize!

It’s the perfect foundation for anyone looking to build a custom chatbot or AI support assistant.

🛠️ Features

• 📞 Simulated customer-agent interaction

• 🔧 Agent decision trees (via OpenAI Assistants API)

• 🌐 Easy frontend integration (React/Next.js)

• 🐍 Clear backend codebase (FastAPI, Python 3.11+)

• 🔑 Plug-and-play with your own OpenAI API Key

⚙️ How to Set It Up (with Windows Compatibility)

Here’s how to get it running on a Windows VPS. These steps assume you're using a PowerShell or Command Prompt environment.

🔐 Step 1: Set Your OpenAI API Key

Get your key from platform.openai.com.

You can either:

• Set it as an environment variable (temporary):

set OPENAI_API_KEY=your_openai_api_key

• Or create a .env file inside the python-backend folder:

OPENAI_API_KEY=your_openai_api_key

📦 Step 2: Install Backend (Python)

In your first console window:

cd python-backend
python -m venv .venv
.venv\Scripts\activate
pip install -r requirements.txt

To start the backend:

set OPENAI_API_KEY=your_openai_api_key
python -m uvicorn api:app --reload --port 8000

💻 Step 3: Install Frontend (Next.js)

In a second console window:

cd ui
npm install
npm run dev

This will launch the frontend on http://localhost:3000 and communicate with the backend on port 8000.

🖼️ Screenshot Preview

The UI provides a live chat interface and a transparent view into the AI’s reasoning, showcasing which tools and actions it invokes during the conversation.

🧩 Use Cases

Whether you're building:

• A SaaS product support bot

• An e-commerce FAQ assistant

• An internal helpdesk tool

This demo is an excellent starting point. With minimal changes, you can connect real data sources, define your own tools, and make the agent truly yours.

⚡ Pro Tips for VPS Deployment

1. Use PM2 or a process manager to keep your backend and frontend running.

2. Use a reverse proxy (e.g., Nginx) to expose ports 3000 and 8000 securely.

3. Use .env files and don't hard-code API keys in production.

4. Scale horizontally: OpenAI Assistants API handles the heavy lifting, so your VPS handles orchestration, not the ML inference.

📚 Conclusion

OpenAI’s Customer Service Agents Demo is more than a tech showcase—it's a ready-to-use boilerplate for anyone looking to build AI-powered support systems.

With support for both Linux and Windows environments, it's an ideal project to deploy on your VPS and experiment with the next generation of conversational agents.

We're excited to announce the brand-new redesign of the VpsGuy website — created to deliver a faster, cleaner, and more intuitive experience for everyone managing VPS servers.

This redesign isn't just cosmetic. We’ve rebuilt the platform from the ground up to focus on clarity, speed, and usability. Whether you’re browsing tutorials, reading the latest blog posts, or exploring our AI-powered tools, everything is now easier to find and faster to load.

What’s New?

• Streamlined Navigation
  A simplified menu structure helps you get to what you need in fewer clicks — whether it’s guides, tools, or our AI assistant.

• Improved Readability
  Cleaner typography and better formatting across all pages make reading long-form content more pleasant and productive.

• Mobile-Friendly Design
  VpsGuy is now fully responsive, so you can manage your server or learn on the go — from any device.

• Faster Load Times
  We've optimized the site to ensure pages load quickly, even in low-bandwidth environments.

• Fresh Visual Identity
  The new look reflects our commitment to innovation, automation, and user-first design.

Why the Change?

As our tools and content evolved, so did the needs of our users. The previous design didn’t fully support our growing library of resources or our vision for a more interactive, AI-driven platform. This update lays the groundwork for smarter, faster VPS management — powered by both community and technology.

Thanks for being part of our journey. We hope you love the new VpsGuy as much as we do.
Your feedback is always welcome!

Why: Microsoft folks decided to “update” the colors by “brightening” the palette in Windows 10 1709. info

So how to revert to old colors: Microsoft released Color Tool . Download it, extract it somewhere and then run this command:

colortool.exe -b schemes\cmd-legacy.ini

This will affect the colors for both the current console and for the default console. Also there is some more alternative color schemes:

colortool.exe -b schemes\campbell-legacy.ini

colortool.exe -b schemes\campbell.ini
