2. • Agentic AI — Introduction & Core Concepts: Introduction to Agentic AI: understanding autonomous, goal-driven AI systems that perceive, plan, act and learn. • Hands-on Practical: Build a Web-Search & Validation Agent: Live coding session where we build an agent that searches the web, validates information, and returns a verified answer. • Q&A & Next Steps: Discuss open questions, limitations and ethical considerations — and brainstorm how you could build your own agentic projects Agenda 26-07-2025
3. Evolution Toward Agentic AI 2021- 2022 DALL·E (OpenAI): Introduced text-to-image diffusion models, sparking the generative art revolution. ChatGPT (OpenAI): Launched in Nov 2022, bringing natural language conversations to the mainstream. 26-07-2025 2023- 2024 2025–2026 GPT-4: Enabled multimodal input (text + image), with enhanced reasoning and controllability. Gemini 1 & 1.5 (Google): Gemini 1.5 pushed boundaries with massive context windows—up to 1 million tokens. the mainstream. Rise of Agentic AI: Autonomous agents emerge, capable of reasoning, planning, and executing tasks independently. Multi-Agent Collaboration: Agents begin functioning like human teams, collaborating across domains like code, business, and research.

5. Strong Suit Make Agent development feels like software development. ADK stands for Agent Development Kit, an open‑source, code‑first toolkit by Google for building intelligent AI agents. Designed from the ground up for multi-agent systems, agents that reason, communicate, and collaborate like a team Google ADK 26-07-2025
6. Google ADK 26-07-2025
7. • Command-Line Interface (CLI): Commands like adk run, adk web, and api_server simplify agent execution and debugging. • Web UI: Visualizes agent definitions, execution steps, and event traces for easier development. • Event-Driven Architecture: Logs every interaction (e.g., user inputs, tool calls, LLM responses) for transparency and debugging. • Session and State Management: Maintains conversational context and memory across sessions. Developer Tools and Capabilities • MCP Integration: Standardizes tool communication, enabling agents to interact with external APIs and databases. • Deployment Flexibility: Supports containerization for deployment across environments, including Google Cloud. • Agent2Agent (A2A) Protocol: Facilitates interoperability between agents across platforms via standard HTTP endpoints. 26-07-2025

19. Last step to apply credit! Set your project’s billing account to Google Cloud Platform Trial Billing Account
20. Issues When attempting to redeem credits It may be unclear where the credits land. If you users are confused, have them navigate to the Credits tab on the page on of the console That is where they will see the credits
21. Issues if the user ALREADY has a existing billing account make sure they use the correct one Click on the 3 Dot menu on the project, and select “Change Billing,” from the drop down select that Google Cloud Platform Trial Billing
