Gemini 3 Usage Example

1. Basic Usage

Prepare a Google account (e.g., Gmail). If you don’t have one, you can register on the official Google website.
Use a browser to visit Google AI Studio (https://aistudio.google.com/) or the Gemini official website (https://gemini.google.com/). Log in to start using it.

2. Basic Operations

Chat Conversation: Enter your question or instruction in the homepage input box, such as “Explain the basic concepts of quantum mechanics” or “Help me write a resignation letter.” Gemini 3 will generate a response in real-time.
Multimodal Input: Supports uploading images, audio, and video. For example, upload a landscape photo and ask “Where was this photo taken?” or upload an audio file for transcription into text.

2. Common Scenario Hands-On

1. Text Creation

Writing Assistance: Input a topic and general structure, and let Gemini 3 generate articles, reports, emails, etc. For example: “Help me write a report on the development trends of artificial intelligence, including current status, challenges, and future directions.”
Creative Writing: Generate stories, poems, scripts. For example: “Write a sci-fi story about a future city where the protagonist is a robotics engineer.”

2. Image Generation

Text-to-Image: Input a description to generate an image, such as “Generate an image of a beach at sunset with palm trees and waves.”
Image-to-Image: Upload a sketch or reference image along with a text description, and let Gemini 3 generate a more refined image based on the reference.

3. Code Generation & Optimization

Input a requirement like “Write a Python function to calculate the Fibonacci sequence,” and you’ll get the code.
Provide existing code for optimization or logic explanation. For example: “Help me optimize this SQL query to improve efficiency.”

4. Learning Assistance

Knowledge Explanation: Ask subject-specific questions, such as “Explain the meaning and application scenarios of Newton’s second law.”
Problem-Solving Guidance: Upload math problems, physics problems, etc., and let it provide problem-solving ideas and steps.

5. Application Development

In Google AI Studio, click “Build,” input a functional requirement (e.g., “Make a simple to-do list app”), and Gemini 3 can generate an interactive web application.
Combine with other tools (e.g., Nano Banana Pro) to create agents for automating tasks.

3. Precautions

Network Environment: Requires a stable internet connection. Some features may require access via a VPN (please comply with local regulations).
Model Selection: Free users default to Gemini 2.5. For advanced features of Gemini 3 Pro (such as deep research, high-definition image generation, etc.), a paid subscription or student discount application is required.
Data Security: Avoid inputting sensitive information. Google may use conversation data for model training.
