Vertex AI Studio Development Guide

by | Jan 31, 2026

Imagine if you could develop an entire financial analyst assistant application without writing a single line of code, and all within just ten minutes. It’s more possible than ever with Google’s Vertex AI Studio and Gemini, as recently demonstrated by Googlers Shubham Saboo and Colby Hawker on the Google Cloud Tech YouTube channel. This tutorial delves into the innovative ‘vibe coding’ feature, enabling developers to utilize prompt instructions to generate a working application seamlessly. The demonstration starts off by addressing common frustrations developers face when kicking off their AI projects – the hassle of securing a cloud account, configuring roles, and setting up an initial environment. Vertex AI Studio aims to eliminate these barriers with its ‘Express mode,’ allowing developers to prototype without a Google Cloud account or credit card.

The central premise explored involves converting PDF earnings reports into structured diagrams with the help of AI agents that refine and optimize prompt instructions. Such an approach not only accelerates the development process but allows developers to create production-ready JSON outputs. While the idea of instantly generating a functional application may sound ambitious, the presenters convincingly guide the audience through each step—from uploading a sample PDF to using AI to transform data into actionable formats.

The integration of the ‘/build’ command highlights the seamless transition from simple prompts to complete applications, an area where the Vertex AI Studio truly shines. By embedding sophisticated agents, developers can scale their projects from basic iterations to complex systems, ultimately moving toward a production environment in Google Cloud’s full account setup. However, it’s important to note the limitation of the ‘Express mode’ being in preview and not universally accessible yet.

On the flip side, while the presentation provides an exciting glimpse into the future of AI-driven development, the current limitations on feature access could leave some developers eagerly awaiting broader availability. There’s also the potential challenge of ensuring that such AI-generated outputs meet the nuanced needs of every unique project. Developers may find themselves questioning whether the optimization tools can handle the diversity of real-world data inputs and outputs consistently.

Despite the limitations, the potential benefits of these advancements in AI development tools stand out. The capacity for a rapid transition from idea to a robust, collaborative, and secure AI agent may dramatically reshape how developers approach building applications. This ambitious demonstration invites developers to explore these tools further, promising a streamlined, efficient path to harnessing the power of AI in practical applications. The session concluded with a compelling roadmap for turning a nascent idea into a scalable, maintainable solution within minutes, making this showcase exciting for developers worldwide.
