OpenAI has officially launched its highly anticipated GPT-5 model and announced that it is now available for free to all users. This company, led by CEO Sam Altman, calls it "the smartest, fastest, and most useful model to date," claiming it provides more accurate responses in fields such as mathematics, science, finance, and law.

Key Features and Promises of GPT-5

At the launch, Altman compared GPT-5 to the "retina display" of the Apple iPhone, emphasizing its high accuracy, making users feel "as if they are talking to an expert on any subject." He openly claimed that GPT-5 is the "best coding model" and "writing model" in the world and also performs well in areas such as healthcare.

GPT-5 is a "reasoning" model that can solve problems through an iterative process to reach the final result. To support this new model, OpenAI is taking decisive action. Researcher Tina Kim said that the company will "phase out all old models" to ensure that GPT-5 becomes its core technology.

OpenAI also claims that GPT-5 solves two major issues that have plagued existing AI models: hallucination problems and cybersecurity vulnerabilities. Although the company states that the new model can more easily connect to Google accounts and has stronger resistance to hijacking attempts, a recent report by Wired magazine shows that ChatGPT still has obvious cybersecurity vulnerabilities, so its security remains to be tested in practice.

Personalization and Future Outlook

GPT-5 offers four preset personality options, including "cynic," "robot," "listener," and "nerd," aiming to enhance the model's customizability.

Although Altman is confident about GPT-5, he admits that OpenAI is still a long way from achieving its core goal: Artificial General Intelligence (AGI). He believes GPT-5 is an important step in that direction and acknowledges that there is still "something very important missing."

Additionally, OpenAI recently released an update that includes "gentle reminders" during long sessions, encouraging users to take breaks to address potential issues such as "ChatGPT psychosis" or delusional problems.

Business and Market Dynamics

Just before the release of GPT-5, OpenAI also launched two models called "gpt-oss-120b" and "gpt-oss-20b," which are "state-of-the-art open-weight language models," but these models are undoubtedly overshadowed by the brilliance of GPT-5.

As a former nonprofit organization, OpenAI's commercial value is rapidly increasing. It has been reported that the company is negotiating a potential secondary stock offering with an estimated valuation of up to 500 billion dollars
