Why Choose Vertex AI?

Vertex AI isn’t just another tool in the AI landscape; it’s a powerful platform that transforms how businesses interact with their audience. Leveraging the same Gemini models that are at the core of Google’s AI offerings, Vertex AI allows you to create sophisticated chatbots that are capable of understanding and generating human-like responses. Whether you’re looking to improve customer support, create engaging user experiences, or simply explore the capabilities of AI, Vertex AI is your go-to solution.


Getting Started: Your AI Playground

Before diving into chatbot creation, let’s set the stage. Here’s what you need:

Step 1: Enter the Google Cloud Universe

Start by creating a new project or selecting an existing one in the Google Cloud Console. Once inside, enable the Vertex AI API along with the Discovery Engine API—this will unlock the tools you need to build and deploy your chatbot.

Step 2: Prepare Your Vertex AI Workbench

In the Google Cloud Console, navigate to Vertex AI and select Workbench. Here, you’ll create a User-Managed Notebook—your playground for writing and running the code that will bring your chatbot to life. Choose your preferred configuration (Python 3 is recommended) and launch your notebook.

Lab 1: Building Your Chatbot with the Gemini API

Task 1: Set Up Your First Notebook

Open your notebook and navigate to the generative-ai/gemini/getting-started folder. Here, you’ll find the intro_gemini_pro_python.ipynb file—this is your starting point. Inside, you’ll install the necessary Vertex AI SDK by running the command:

!pip3 install google-cloud-aiplatform

Restart the kernel to ensure everything is set up correctly.


Task 2: Explore the Gemini API

Now comes the fun part. Import the necessary libraries and load your Gemini model using the following commands:

from google.cloud import aiplatform
from google.cloud.aiplatform.gapic.schema import predict

To test your setup, generate some text with a simple prompt:

response = model.predict({"prompt": "Hello, how can I help you today?"})
print(response)

Lab 2: Advanced Features with Vertex AI Agent Builder

Task 1: Enable Additional APIs

To take full advantage of Vertex AI, enable the Discovery Engine API. This allows you to test more creative queries and explore the capabilities of the text-bison@001 model:

response = model.predict({"prompt": "Tell me about the first elephant on the moon."})
print(response)

Task 2: Create a Data Store for Grounding

Grounding your chatbot with a solid data foundation is crucial for accuracy. In the Vertex AI Agent Builder, create a new Data Store using Google Cloud Storage (GCS). Set the GCS folder path and link your Data Store to ensure your chatbot has access to the information it needs.

Task 3: Build and Test Your Search App

With your Data Store ready, it’s time to create a Search App in the Vertex AI Agent Builder. This app will allow your chatbot to handle complex queries, providing accurate and contextually relevant responses. Test your app with various queries to see how well it performs and make adjustments as needed.

Fine-Tuning and Customizing Your Chatbot

Creating a basic chatbot is just the beginning. Fine-tuning is where your chatbot becomes truly unique. By training your Gemini model with specific datasets, you can tailor responses to fit your brand’s voice and style. This process involves creating a dataset with examples of desired responses and using Vertex AI to train your model, making it smarter and more aligned with your needs.

Grounding with Data Stores

Grounding is about ensuring your chatbot has a reliable base of knowledge to draw from. By linking your Vertex AI Agent Builder app to your newly created Data Store, your chatbot will have access to the most relevant and up-to-date information, improving its accuracy and reliability.

Bringing Your Chatbot to Life

Once your chatbot is fine-tuned and ready, it’s time to deploy it. Use Vertex AI Studio to handle deployment, configuring settings and endpoints to ensure seamless operation. Once deployed, integrate the chatbot into your website using APIs or SDKs. Test the interaction between your chatbot and website to guarantee a smooth user experience.

Beyond the Basics: Expanding Your AI Capabilities

Vertex AI is a powerful tool with applications far beyond basic chatbot creation. Here’s how you can leverage it for more advanced projects:

  • Machine Learning and AI Models: Use Vertex AI to create predictive models, natural language processing tools, and more.

  • Big Data Analytics: Analyze massive datasets in real-time to uncover insights and trends.

  • Recommendation Systems: Build personalized recommendation engines for eCommerce, streaming platforms, and more.

  • Image and Video Recognition: Develop AI models capable of understanding and categorizing visual content.

Final Thoughts: Your AI Journey Begins Now

Congratulations! You’ve just built your first chatbot using Google’s Vertex AI. But this is only the beginning. At The Shakti Agency, we believe in pushing the limits of what’s possible. Keep experimenting, refining, and expanding your AI capabilities. The future of business is AI-driven, and you’re now equipped to lead the way.

Stay creative, stay innovative, and most importantly, have fun with AI!
