Since its launch in 2022, the development journey of ChatGPT has marked a significant transformation in human-computer interaction. From being an initial novel experiment, it has rapidly grown into an indispensable digital tool in the daily lives of many people.

According to statistics, ChatGPT attracted over one million users within just five days of its launch. By November 2023, the number of weekly active users had reached 100 million, and by August 2024, this figure had surpassed 200 million, with monthly visits reaching approximately 3.1 billion times. Such an astonishing user base reflects the widespread application of ChatGPT in daily life.

With the continuous progress of technology, ChatGPT launched the GPT-4o version in May 2024, achieving multimodal interaction. This upgrade enables the AI to process and generate text, images, and audio, greatly enriching the user experience. Whether it is in summarizing legal documents, analyzing medical images, or generating concepts in the creative industries, GPT-4o has demonstrated its potential as an important part of the workflow.

In October 2024, ChatGPT introduced the search function SearchGPT, which has elevated the search experience to a new level. Unlike traditional search engines, SearchGPT provides comprehensive and contextually relevant answers, completely changing the way users obtain information. Although Google has long dominated the search market, its market position is being challenged under the impact of ChatGPT.

As ChatGPT's capabilities continue to improve, it has gradually entered ordinary households and become a household assistant. Whether it is arranging schedules, solving technical problems, or helping children with their homework, ChatGPT handles these tasks with ease. This universality is what sets it apart. Meanwhile, Google's response in this area seems to be lagging. The internal structural complexity and risk aversion have slowed down its innovation speed, making it unable to adapt to market demands in a timely manner.

However, ChatGPT is not without challenges. Although its performance in some areas is commendable, there still exists the "hallucination" problem, that is, the AI may generate seemingly reasonable but actually inaccurate information. This could affect users' trust in critical fields such as healthcare and law, so OpenAI has made solving this problem a top priority.

With the widespread application of ChatGPT, ethical issues have gradually emerged. A study shows that many parents trust ChatGPT's medical advice more than that of professional medical staff. This phenomenon reminds us to be cautious when relying on AI advice. In addition, privacy and data security issues cannot be ignored either. OpenAI has taken measures to enhance the privacy protection of user data, but the discussion on AI ethics continues.

In the future, OpenAI plans to further improve ChatGPT's reasoning ability and accuracy through new models to enhance the user experience. The rapid development of AI tools will undoubtedly change our ways of living and working. As more and more companies invest in the AI field, ChatGPT will continue to deepen its application in both professional and personal lives, and the pressure from competitors such as Google will become more and more significant.
