4. Hello to
6. Enterprise Vertex AI Studio Google Cloud APIs cloud.google.com/vertex-ai Consumers Gemini gemini.google.com Developers Google AI Studio Google APIs aistudio.google.com ai.google.dev/gemini-api
7. Unified SDK
8. Using environment variables Gemini Developer API on Google AI Studio export GOOGLE_API_KEY='your-api-key' Gemini Developer API on Vertex AI export GOOGLE_GENAI_USE_VERTEXAI=true export GOOGLE_CLOUD_PROJECT='your-project-id' export GOOGLE_CLOUD_LOCATION='us-central1' client = genai.Client() Common client initialization
9. Native Tool Use
10. Google Search Tool Ground model responses in Google Search results For more accurate, up-to-date, and relevant responses
11. Why grounding? Ask an LLM: ⚛Explain Einstein’s Relativity 🪐How many moons does Saturn have? ⌚What time is it today? 🌤What is the weather like in Zurich?
12. Google Search Tool google_search_tool = Tool(google_search=GoogleSearch()) response = client.models.generate_content( model="gemini-2.0-flash-001", contents="How’s the weather like today in Zurich ?", config=GenerateContentConfig(tools=[google_search_tool]) )
13. Rio de Janeiro Demo3 Demo3: In Vertex AI Studio, show this prompt without and with Google Search grounding and also show the code: Whats the weather like today in Zurich? Use Celsius and JSON format
14. Automatic Function Calling Submit a Python function for automatic function calling (instead of submitting an OpenAPI specification of the function)
15. Automatic Function Calling def get_current_weather(location: str) -> str: """Example method. Returns the current weather. Args: location: The city and state, e.g. San Francisco, CA """ weather_map: dict[str, str] = { "Barcelona": "sunny", "Paris": "foggy", "Milan": "raining", "Rome": "hot", "London, UK": "rainy and dark", } return weather_map.get(location, "unknown")
16. Manual Function Calling (before)
17. Automatic Function Calling response = client.models.generate_content( model="gemini-2.0-flash-001", contents="What is the weather like in Zurich?", config=GenerateContentConfig( tools=[get_current_weather], temperature=0))
18. Multimodal Live API
19. • Multimodality – model can see, hear, speak • Low-latency – for real-time interaction • Memory – model remembers the session • Tools – Function calling, code execution, and Google search Multimodal Live API–key capabilities
20. Rio de Janeiro Dem Demo6: First, show that Live API is available in Google AI Studio. Then, show 1-2 of these starter apps: cd ~/git/pvt-gemini20
21. Ricc Demo

32. Make me a captivating endless runner game. Key instructions on the screen. p5js scene, no HTML. I like pixelated red dragons and dungeon-like backgrounds. Oh wow this is amazing! Now please change the code in two ways: When you start you can choose among 4 named characters: a red dragon ("Ale"), a giraffe ("Seby"), a puffin ("Papino") or a waffle ("waffle"). Less pixelated than it is now please. with SPACE you have single/double jump - as it is with letter "f/F" you spit fire on obstacles and destroy them with a mini explosion effect. This gives you five points
33. Rio de Janeiro Dem Demo8: go to gemini.google.com => paste this: Make me a captivating endless runner game. Key instructions on the screen. p5js scene, no HTML. I like pixelated red dragons , ogres, gelatinous cubes, goblins. zombies and dungeon-like backgrounds. Try on both 2.5flash and 2.5pro then https://editor.p5js.org/
34. Dungeon Runner Smurfs & Dragons (maths) 3D Googley Lego Tetris zurigram.web.app/
35. Friends will be friends.. sometimes My friend Paolo: “I love it for my daughters, can you add Lithuanian and Dutch?” Riccardo: “no way! No time for that” Paolo: “Ok, I’ll try myself! Don’t give me the prompt!” …
