📖 Lesson Start

How Gemini 3 Evolved, and How It Compares with ChatGPT

🗣 (S)

I heard that Gemini 3 is a big update, but I’m not sure what exactly changed.
Is it “just faster,” or is it something more fundamental?

🎓 (T)

Great question. Gemini 3 is not just a speed upgrade.
It represents a shift in how Google wants AI to behave.

Earlier models mainly focused on text generation and some image capabilities.
But Gemini 3 aims at something larger:

to function as a reasoning partner, a multimodal worker, and an agent that can take action.

Let’s walk through what changed, step by step.

🔹 1. Deep Reasoning Power: A Major Leap Forward

🗣 (S)

“Reasoning” sounds a bit abstract. How do I feel the improvement in real use?

🎓 (T)

Think of reasoning like the ability to solve a puzzle that has many pieces.
Older AI models could respond well when the question was simple or direct.
But complex tasks—those requiring multiple steps—were challenging.

Gemini 3 improves this in several ways:

① Multi-step logical thinking

It can follow a chain of logic:
“If A happens, then B becomes possible, and because of C, the best choice is D.”

This makes it useful for:

Business planning
Writing long documents
Analysing data relationships
Solving math or logic tasks
Understanding cause-and-effect in complex situations

② Gemini 3 “Thinking” mode

You can choose which mode to use depending on your purpose.

Thinking mode gives the model time to think more deeply before producing an answer.
It performs better in:

Structural planning (ex. long reports, lesson plans, business frameworks)
Mathematical reasoning
Software architecture
Advanced brainstorming

It feels more like talking to a colleague who takes time to consider the whole picture.

🗣 (S)

So it’s not only giving answers faster—it gives better answers?

🎓 (T)

Exactly.
Gemini 3 is designed for slow, deliberate thinking when needed, not only quick replies.

🔹 2. Stronger Multimodal Ability

🗣 (S)

I heard that Gemini is especially good with images and video.
Is that a big difference compared to earlier versions?

🎓 (T)

Yes. Gemini 3 is much more capable across different types of data.

It can read, interpret, and generate across:

Text
Images
Audio
Video
Code

And not just individually—in combination.

Examples of practical use

“Explain this chart and write a summary for my report.”
“Read this scanned document and extract important points.”
“Look at this UI screenshot and generate the HTML/CSS code.”
“Watch this short video and describe its main actions.”
“Generate an image for my presentation.”

This makes the model helpful for business, design, research, and content creation.

🗣 (S)

So Gemini is like an assistant who can “see” and “hear,” not only “read”?

🎓 (T)

Exactly.
Gemini 3 moves beyond writing: it becomes a tool that interacts with your world.

🔹 3. Agent-Style Behavior & Coding Support

🗣 (S)

What does “agent-style” mean? I hear this a lot recently.

🎓 (T)

Great question.
An agent is an AI that does more than answer questions—it performs tasks.

Gemini 3 takes steps toward this approach.

It can:

Read your entire codebase
Suggest improvements
Modify files
Debug step-by-step
Explain complex code
Help plan features
Generate tests

Google clearly intends Gemini to be a software development partner, not just a chatbot.

🗣 (S)

So Gemini 3 is targeting engineers and technical teams?

🎓 (T)

Yes.
While anyone can use it, Google designed parts of Gemini 3 to behave like:

“an AI teammate inside your workflow.”

This is different from ChatGPT’s approach, which is strong in creativity and conversation, but Gemini 3 aims more at system-level tasks.

🔹 4. Deep Integration with Google Ecosystem

🗣 (S)

I use Gmail, Google Drive, and Docs every day.
Does Gemini 3 work smoothly with them?

🎓 (T)

This is one of Gemini’s biggest strengths.

Gemini 3 integrates deeply with:

Gmail
Google Docs
Sheets
Drive
Calendar
Google Search
Android apps

This means:

You can ask Gemini to draft emails using your Gmail history.
It can summarise your documents in Drive.
It can analyse spreadsheets in Sheets.
It can schedule things using Calendar.
It can pull real-time information using Search.

This creates fast real-world usability.

🗣 (S)

So Gemini is like an assistant living “inside” my Google life?

🎓 (T)

Exactly.
If you work in Google Workspace, Gemini feels natural and efficient.

🧭 Comparison: Gemini 3 vs ChatGPT

Now let’s compare them across several dimensions.

🔹 1. Ecosystem & Workflow Integration

Gemini

Best for people already using Google Workspace
Strong integration with email, documents, calendars, files
Real-time information retrieval through Google Search

ChatGPT

Best for people building customized workflows
GPTs and plugins allow specialized tasks
API ecosystem is advanced and flexible

🗣 (S)

So Gemini fits “office and business life,”
and ChatGPT fits “custom tools and creative workflows”?

🎓 (T)

Perfect summary.

🔹 2. Information Freshness

Gemini

Uses Google Search foundation
Very strong real-time information retrieval
Reliable for fact-checking and up-to-date content

ChatGPT

Mainly uses training data
Browsing is possible, but not as deep as Google
Sometimes slower in acquiring the latest info

🔹 3. User Experience (UI/UX)

Gemini

Easy for Google users
Notebook-style interface supports long, structured work
Feels like part of your existing tools

ChatGPT

Clean, simple interface
Very intuitive for beginners
Natural and human-like conversation style

🔹 4. Strengths & Ideal Users

Gemini Strengths

Logical structure
Data organization
Technical documents
Coding inside large systems
Real-time information
Google-integrated workflows

Ideal users:
Business professionals, researchers, engineers, and anyone who lives inside Google Workspace.

ChatGPT Strengths

Creative writing
Emotional expression
Brainstorming and idea exploration
Teaching and explanation
Natural conversation
Custom AI agents (GPTs)

Ideal users:
Creators, writers, planners, educators, and people who want a conversational partner for thinking.

🔹 5. Practical Usage Decision

🎓 Quick Rule of Thumb

If your goal is “work efficiency,” choose Gemini.

Because it integrates with Google Docs, Sheets, Gmail, search, and real-time data.

If your goal is “creative or conceptual thinking,” choose ChatGPT.

Because its language style, narrative ability, and expressive depth are unmatched.

🗣 (S)

So I don’t need to choose one model forever?
I can simply switch depending on the task?

🎓 (T)

Exactly. That’s the best strategy.

AI is not about choosing a single tool—
it is about knowing which tool solves which problem.

You will be far more productive when you match your task with the right model.
