The Gemini ecosystem has evolved into a comprehensive suite of models, tools, and APIs. Whether you are “vibe-coding” a web app or deploying enterprise-grade agents, navigating the options can be overwhelming.
I am happy to announce a new Gemini for Developers codelab. This codelab is designed to teach you everything you need to know about the Gemini ecosystem, from the different model flavors to tools powered by Gemini to integration using the Google Gen AI SDK and the new Interactions API.
What you will learn and build
This codelab takes you through the full spectrum of Gemini products, including Google AI Studio for fast prototyping, Vertex AI Studio for enterprise deployment, and developer tools like the Gemini CLI and Google Antigravity.
Here is a look at the specific capabilities you will explore:
- The unified SDK: Learn to use the Google Gen AI SDK (supporting Python, Go, Node, Java, and C#) to interface with models on both Google AI and Vertex AI.
- Advanced reasoning: Experiment with Thinking Mode, where you can control the model’s internal reasoning process and budget.
- Long context: See how to leverage the 1 million+ token context window to process massive inputs, such as extracting chapters from video files.
- Agentic workflows: Dive into the Interactions API and Google Antigravity to build agents capable of planning, executing complex tasks, and conducting deep research.
- Multimodal magic: Generate images with Nano Banana, create speech with text-to-speech models, and engage in real-time voice and video conversations using the Live API.
- Grounding: Learn to connect model responses to real-world data using built-in tools like Google Search, Google Maps, and Code Execution.
Who is this for?
This codelab is for everyone. If you are just starting, you can use the Gemini App to generate basic code. If you are building applications requiring local context, you will learn how to utilize Gemini CLI or Antigravity. For those needing to deploy to the cloud, the guide covers Vertex AI.
