Ultimate Handbook : Google Certified Generative AI Leader

I followed this guide myself and got certified, and now I’m sharing it with you.

Are you ready to become a certified Generative AI Leader on Google Cloud? This certification is designed for professionals who want to bridge the gap between business strategy and cutting-edge AI technology. As a Generative AI Leader, you’ll demonstrate your ability to identify gen AI use cases, leverage Google Cloud’s tools, and drive responsible AI adoption in organizations. It’s not about coding or deep technical implementation — it’s about strategic vision, collaboration, and innovation.

Handwritten notes! And there are lots of it.

Don’t worry about trying to read those notes! I’ve created something much more readable that will help you master every topic before you take your exam.

How This Handbook Is Structured

This handbook is a step-by-step guide built around the official exam outline. It combines Google Cloud’s official study materials with real-world examples, additional references, and practical insights. Whether you’re a business executive, IT leader, or an AI enthusiast, this breakdown will help you prepare effectively.

The exam is divided into four sections with the following weight:

  • Section 1: Fundamentals of Gen AI (~30%)
  • Section 2: Google Cloud’s Gen AI offerings (~35%)
  • Section 3: Techniques to improve Gen AI model output (~20%)
  • Section 4: Business strategies for a successful Gen AI solution (~15%)

Let’s dive in!

Section 1: Fundamentals of Generative AI (~30% of the Exam)

This section tests your foundational knowledge of generative AI concepts, machine learning basics, data types, and Google’s models. Focus on understanding how these elements apply to business scenarios.

1.1 | Core Concepts and Use Cases

Understand the key concepts and their distinctions:

  • Artificial Intelligence (AI): Machines that mimic human intelligence to perform tasks like learning and decision-making. Generative AI is accelerating the current “golden phase” of AI, where systems create new content like text, code, and images.
  • Machine Learning (ML): A subset of AI where systems learn from data without explicit programming. Unlike traditional programming, which uses rules (e.g., “IF this THEN that”), ML learns from examples.
  • Generative AI (Gen AI): A type of ML that creates new content. Instead of just predicting, it can write emails, generate code, or design images.
  • Foundation Models: Large, adaptable models trained on vast datasets. They are “foundational” because they can be fine-tuned for a wide range of specific tasks.
  • Multimodal Foundation Models: These models handle multiple data types simultaneously, such as text, images, and audio.
  • Diffusion Models: A class of generative models that create data by reversing a noise-adding process, commonly used for image and video generation.
  • Prompt Engineering: The art of crafting inputs (prompts) to guide a model to produce the desired output.
  • Large Language Models (LLMs): A type of foundation model specialized in language, trained on massive amounts of text.

There are broadly three types of ML Approaches:

  • Supervised Learning: Uses labeled data to predict outcomes (e.g., classifying emails as spam).
  • Unsupervised Learning: Finds patterns in unlabeled data (e.g., grouping photos by faces).
  • Reinforcement Learning: Learns through trial and error with a system of rewards (e.g., an AI learning to play a game).

You should also be familiar with the ML lifecycle and the corresponding Google Cloud tools:

  1. Data Ingestion & Preparation: Tools like BigQuery or Dataflow for collecting and cleaning data.
  2. Model Training: Use Vertex AI or AutoML to train your models.
  3. Model Deployment: Deploy models for use with Vertex AI Endpoints.
  4. Model Management: Monitor performance with Vertex AI Model Monitoring and manage versions in the Model Registry.

When choosing a model, consider:

  • Modality: What type of data will it handle (text, images, audio)?
  • Context Window: How much input can the model process at once?
  • Security & Reliability: What are the uptime guarantees and data handling policies?
  • Cost & Performance: How do you balance speed and accuracy?
  • Customization: What options are available for fine-tuning the model?

Generative AI can be used to:

  • Create: Generate marketing copy, product designs, or code.
  • Summarize: Condense lengthy reports for executives.
  • Discover: Analyze data for insights, such as trend forecasting.
  • Automate: Generate personalized recommendations or customer service responses.

1.2 | Data Types and Their Business Implications

This section emphasizes the characteristics and importance of data.

  • Data Types: Differentiate between structured (organized data like spreadsheets) and unstructured(free-form data like emails or videos). Similarly, know the difference between labeled (tagged data for supervised learning) and unlabeled (raw data for unsupervised tasks).
  • Data Quality: High-quality data is essential for reliable AI. Poor data can introduce bias or lead to inaccurate outputs. Key characteristics include completeness, consistency, relevance, and availability.

1.3 | The Core Layers of the Gen AI Landscape

Understand the layers of the generative AI stack and their business implications:

  • Infrastructure: The hardware layer, like Google Cloud’s GPUs and TPUs, which enables scalable computing.
  • Models: The algorithms trained on data, such as LLMs.
  • Platforms: The tools that simplify deployment and management, like Vertex AI.
  • Agents: Software that uses tools to act on specific goals, such as a chatbot.
  • Applications: The user-facing tools, like the Gemini app, that drive productivity.

1.4 | Google’s Foundation Models

Know the use cases and strengths of Google’s key models:

  • Gemini: A multimodal model excellent for conversational AI and content creation. It can handle text, images, code, and more.
  • Gemma: A family of lightweight, open models optimized for on-device and local deployments. This includes CodeGemma (for programming) and PaliGemma (for visual data).
  • Imagen: Specialized in high-quality text-to-image generation and editing.
  • Veo: Generates high-quality videos from text or images.

Section 3: Techniques to Improve Gen AI Model Output (~20% of the Exam)

This section covers how to mitigate limitations and optimize model outputs.

3.1 | Overcoming Foundation Model Limitations

Be prepared to identify and address common issues:

  • Data Dependency: Models can reflect biases from their training data.
  • Knowledge Cutoff: Models are only aware of information up to their last training update.
  • Hallucinations: Models can generate false or nonsensical information.
  • Bias and Fairness: Models can produce biased outputs, which can have real-world consequences.
  • Edge Cases: Models may fail in rare or unusual scenarios.

Use these techniques to mitigate limitations:

  • Grounding: Tying a model’s output to a verifiable source of data.
  • Retrieval-Augmented Generation (RAG): Augmenting a prompt with retrieved information from an external data source to improve accuracy.
  • Prompt Engineering: Crafting prompts to guide the model.
  • Fine-Tuning: Training a model on a smaller, task-specific dataset.
  • Human-in-the-Loop (HITL): Using human reviewers to validate AI outputs.

3.2 | Prompt Engineering Techniques

Master these techniques to get the best results from a model:

  • Zero-shot: Prompting with no examples.
  • One-shot/Few-shot: Providing one or more examples to guide the model.
  • Role Prompting: Assigning a persona to the model.
  • Chain-of-Thought: Asking the model to “think out loud” and show its step-by-step reasoning.
  • ReAct (Reasoning + Action): A powerful technique that combines reasoning with the ability to take actions, such as using an API to get real-time data.
I would highly recommend to read my article on Context Engineering to get more in-depth details about Context of LLMs.

Context Engineering is here…because prompts alone don’t scale

3.3 | Grounding Techniques
