Vertex AI Review: Google’s Most Complete AI Platform?

Vertex AI

    What is Vertex AI?

    Google offers a robust platform for designing intelligent agents that combine deterministic flows, complex reasoning, and generative responses based on LLM models like Gemini. This solution enables scaling multichannel applications with a secure infrastructure integrated into the Google Cloud ecosystem. Visual drag-and-drop interface; no-code frameworks supported.

    ✅Combines intent-based guided flows designed in Dialogflow CX with generative responses via Vertex AI and Gemini, all within an enterprise-class infrastructure that enables contextual reasoning and conversational adaptability.
    ✅Thanks to the open Agent2Agent (A2A) protocol, agents built on frameworks such as ADK, LangChain, Crew AI, and others can collaborate seamlessly, acting as a coordinated team of agents.
    ✅Vertex AI connects agents with over 100 pre-integrated tools, custom APIs through Apigee, enterprise flows, and RAG capabilities with Vertex AI Search, all within an environment protected by the MCP Protocol.

    Leading platform for developing intelligent, scalable, and multilingual agents.

    Frequently Asked Questions

    Is Vertex AI better than OpenAI GPTs?

    Vertex AI is an enterprise-grade platform for building, deploying, and managing large-scale AI models, offering greater control and customization options. OpenAI GPTs is a much simpler, no-code way to create custom AI agents for specific tasks.

    How much does Vertex AI cost?

    Vertex AI has a complex pay-as-you-go pricing model based on computing resource usage, model training, and predictions. It’s geared toward enterprise budgets.

    Does Vertex AI work for small businesses?

    It’s generally too complex and expensive for a typical SMB, unless they have a dedicated AI development team. For most SMBs, OpenAI GPTs or no-code chatbot platforms are more suitable. Developers can build and deploy large-scale AI models with greater control and security.
