A no-code interface within Vertex AI (now part of Gemini Enterprise Agent Platform) for experimenting with foundation models: testing prompts, tuning inference parameters (temperature, top-k, top-p), and comparing responses before integrating a model into an application.
In GENAI-L (Domain 2) it is distinguished from Agent Builder: Studio is for rapid prototyping and prompt exploration on a model, while Agent Builder orchestrates tools, data, and multi-step flows to build a complete agent.
Vertex AI Studio is a concept that can show up on the exam. Check the full guide to see it in context.
