Google Gemini 2.5 Pro Finally Launches!

— Has It Surpassed ChatGPT? The Dawn of AI War Chapter 2 —

Hello, everyone. Today, we'll explore the major news that has been shaking the tech world in early November 2025: "Google Gemini 2.5 Pro's Major Update". The AI evolution race has finally entered the next phase. OpenAI, Anthropic, and Google — let's take a closer look at what evolution "Gemini 2.5 Pro" has achieved and why it's being said to have "surpassed ChatGPT?"

Introduction: Early November, The World Changed

This news was reported around November 3-4, 2025. American tech media outlets such as "9to5Google," "The Verge," and "Android Authority" simultaneously reported on Gemini 2.5 Pro's update content. Shortly after, the topic spread across Japanese media, and social networks were filled with voices saying "Gemini is amazing" and "Google's comeback."

Google's official blog also announced it around the same time, with the following statement:

"Built on Gemini 2.5 Pro, it handles complex tasks like navigating websites and filling out forms, offering faster performance and improved reasoning."

In other words, it has evolved into an AI that is "faster, smarter, and capable of actual operations." This single statement sent shockwaves through the global AI industry.

Chapter 1: What Has Changed in Gemini 2.5 Pro?

1. The Arrival of the "Computer Use" Model

The biggest focus is the emergence of the Computer Use model. This is a mechanism that allows AI to "operate computers on behalf of humans." For example, it can automatically perform tasks like form input, web page navigation, and file operations.

To put it simply, while previous AI was like a "brain," this time it has gained "limbs." If ChatGPT is a "brain" type that thinks about text, Gemini has evolved into an AI that "thinks and acts."

2. Model Deprecation and Official Release Transition

• gemini-2.5-pro-preview-06-05
• gemini-2.5-flash-preview-05-20 and others are scheduled to be deprecated on November 18.

The API changelog dated November 4 announced the end of older preview models.

This means Google has "moved beyond the preview stage and transitioned to an official release." It's like a beta version becoming a stable version for smartphone apps. This is evidence that the technology has matured and the development cycle has stabilized.

3. Significant Improvements in Reasoning Performance and Speed

Gemini 2.5 Pro adopts what's called a "thinking model." Rather than simply answering questions, it goes through an internal process of "hypothesis → verification → conclusion" before providing a response.

According to DeepMind, in fields such as mathematics, science, and coding, it achieved an 88.0% score on the AIME 2025 test. This is said to match or exceed ChatGPT-4 levels.

Furthermore, processing speed has also improved. The lightweight model "Gemini 2.5 Flash" is reported to have achieved 20-30% efficiency improvements with equivalent performance.

Chapter 2: Why Is It Said to Have "Surpassed ChatGPT?"

Let's analyze the headline "Has it surpassed ChatGPT?"

1. The AI War Landscape

• OpenAI (ChatGPT)
• Anthropic (Claude 3.5)
• Google (Gemini 2.5)

These three powerhouses lead the current generative AI market. Gemini 2.5, in particular, is differentiating itself with its high multimodal capabilities (understanding images, audio, and video simultaneously) and strong integration with Google services.

2. The Meaning of "Surpassed?"

This phrase does not mean "game over." It means that there are areas where it has an advantage in benchmarks (performance tests). In reality, ChatGPT's strengths in natural language generation and stability remain strong. On the other hand, Gemini excels in tool integration, multimodal capabilities, and speed.

In other words, "which one is 'better' depends on the user." Even so, the phrase "surpassed?" captures people's interest because it's evidence that the speed of AI evolution has exceeded imagination.

Chapter 3: Practical Uses and Possibilities

1. For Creators and Individual Users

• Code generation
• Image and video analysis
• Voice input responses
• Document summarization

Gemini 2.5 Pro can perform not only text generation but also:

All of these can be done quickly and accurately. The era has arrived where YouTube scripts, blog posts, and business emails can all be completed in minutes.

2. For Developers and Enterprises

The fact that AI can operate browsers and operating systems opens up possibilities beyond the concept of business automation (RPA). For example, "automatically filling expense forms" or "registering data in Google Sheets" — AI that performs human tasks is becoming a reality.

3. Applications in Learning and Education

Thinking models can explain "why" something is the case, not just provide answers. This characteristic is highly valuable for educational AI, and the fact that students can learn "thinking processes" is a major advancement.

Chapter 4: Benefits and Considerations

Benefits

1. Significantly improved processing speed and efficiency
2. Can understand long text, images, and video together
3. Capable of actual operations (Computer Use)
4. High compatibility with the Google ecosystem

Considerations

1. Some features are paid or region-restricted
2. Migration costs from older versions
3. Safety and misinformation risks still exist
4. The 'surpassed' expression is limited to specific fields

Chapter 5: Summary — The Beginning of the Next-Generation AI Era

Everyone, this news doesn't mean just feature additions. It means AI has entered a phase where it can "think" and "act."

• Long text processing capability (up to 1,000,000 tokens)
• Multimodal understanding (images, video, audio)
• Practical operation model (Computer Use)

Gemini 2.5 Pro has transformed how AI is used with three major elements:

ChatGPT, Claude, Gemini — all of these AIs continue to evolve. However, the "dawn of Chapter 2" that Google showed this time will likely be a catalyst that makes future AI competition even more interesting.

A Question for Everyone

When AI becomes capable of "thinking and acting," what should humans do? It's the ability to correctly distinguish between "what to leave to AI" and "what humans should decide." The evolution of Gemini 2.5 marks the beginning of an era where we master the use of AI.
