Unlike chatbots, generative AI agents—also known as agentic AI—are set to revolutionize AI architecture by autonomously handling complex tasks that typically require human intervention. 

In April 2024, Google Cloud introduced Vertex AI Agent Builder, a tool that lets you create AI-powered conversational agents without writing any code. 

But Vertex AI offers much more than just an AI agent builder. This article will walk you through all you need to know about Google Vertex AI—its features, pricing, how to use the platform, and best alternatives like Voiceflow.

What’s Vertex AI?

Vertex AI is Google Cloud’s fully managed platform designed for building, deploying, and managing machine learning and generative AI models. 

First launched in May 2021, Vertex AI simplifies the entire machine learning workflow for businesses and developers by integrating a wide range of tools and services into a single, cohesive platform. 

Here’s an in-depth look at its capabilities:

  • End-to-End ML Model Management: Train, test, tune, and deploy machine learning models on a single platform. Vertex AI supports 150+ foundation models including Gemini 1.5 Pro. 
  • MLOps Integration: Automate, standardize, and manage machine learning projects with MLOps tools. This ensures continuous integration and deployment (CI/CD) of models. 
  • Generative AI with Gemini: Quickly build and deploy generative AI applications using Gemini, which enhances performance with long context understanding and multimodal capabilities, enabling the integration of audio, video, text, and code inputs.
  • Enterprise-Ready AI Agents: Vertex AI’s no code conversational AI builder supports the creation of sophisticated AI agents that can handle complex tasks.
  • Specialized AI Solutions: Deploy Google Cloud’s AI solutions, such as Anti Money Laundering AI, easily. These pre-built solutions help businesses address specific challenges with minimal setup.

The Generative AI Studio allows you to focus on fine-tuning and customization rather than building models from scratch. 

Vertex AI Agent Builder

Vertex AI is a platform for building, deploying, and managing intelligence search and conversation applications. 

Here are the key features of Vertex AI’s Agent Builder:

  • Advanced Integrations: Supports integrations with frameworks like LlamaIndex and LangChain for enhanced AI capabilities.
  • RAG: Uses Retrieval Augmented Generation to combine LLM-generated responses with real-time data retrieval and enterprise data for more accurate and context-aware interactions.
  • NLU: Advanced natural language understanding for accurate query responses, supporting multiple languages.
  • No-code Development: Use the visual drag-and-drop interface to create AI agents without a single line of code.

Vertex AI Agent Use Cases

There are four types of agents that you can build using Google’s Vertex AI: 

  1. Customer agents: travel booking, manage orders, FAQ bots
  2. Employee agents: employee onboarding, invoice payments, inventory management
  3. Knowledge agents: legal, sales, customer support
  4. Voice agents: contact center, food ordering, automobiles

What Are the Disadvantages of the Vertex AI Agent Builder

Vertex AI Agent Builder, while powerful, has some limitations. It offers less customization than building agents from scratch, may struggle with scalability for highly complex applications, and is heavily dependent on Google Cloud services. There can be an initial learning curve despite its no-code interface, and extensive use of advanced features may lead to higher costs. 

Vertix AI Pricing

Vertex AI offers a free tier with limited usage, allowing you to try out the platform at no cost. This free tier includes a specific amount of usage for services like training and predictions. Beyond the free tier, pricing is based on your usage of various services, such as training hours, prediction hours, and data storage. For example, model training starts at $0.10 per training hour for standard models. For additional data, such as video, text, image processing, rates range from $0.0001 to $0.008 per unit.

Vertex AI Competitors and Alternatives

There are several free and paid alternatives to the Google Vertex AI Agent Builder, including Voiceflow, Dialogflow, Rasa, Amazon Lex, and IBM Watson Assistant. 

If you’re looking for the best free alternative to Vertex AI Agent Builder, choose Voiceflow—the number one AI agent builder trusted by 250,000+ teams, from Home Depot to LVMH. Here’s why:
