ChatGPT's power source, GPT-5, unveiled by OpenAI as the cutting-edge model

In a groundbreaking development, OpenAI has unveiled GPT-5, the next generation of the AI model that powers ChatGPT. This latest iteration, released in August 2025, promises significant improvements and new capabilities over its predecessors [1][2][3][4][5].

One of the key advancements is the Smart Real-Time Router. GPT-5 automatically selects the best internal model for each task, eliminating the need for users to manually choose between speed or reasoning-focused models. This results in a seamless balance of speed, depth, and accuracy [1][3][5].

Users can now tailor the chatbot's tone and style to their needs by choosing from four preset personalities—cynic, robot, listener, and nerd. This feature, known as Multiple Personalities, makes interactions feel more natural and context-appropriate [1].

GPT-5 also demonstrates improved reasoning, problem-solving, and structured thinking. These advancements have been found useful for scientific and ambiguous contexts, producing more reliable, high-quality outputs at faster speeds [2].

The model excels at complex, multi-step tasks involving tool calls, following instructions, handling tool errors, and retrieving long-context content. It achieves state-of-the-art results on recent benchmarks in advanced tool use and agentic tasks [4].

GPT-5 is available in three sizes (regular, mini, nano), each with selectable reasoning levels (minimal, low, medium, high). This flexibility supports a wide range of use cases, including long text inputs (up to 272,000 tokens) [3].

Developers benefit from new API features, such as a verbosity parameter to control answer length and detail. GPT-5 can thus produce answers from concise to comprehensive depending on needs [4].

In the realm of coding, GPT-5 achieves leading benchmark scores in real-world coding tasks, slightly outperforming competitor models like Anthropic’s Claude and Google DeepMind’s Gemini. It can generate entire software applications on demand [5].

While GPT-5 leads in many domains, it underperforms some frontier AI models in certain tests. This nuanced performance landscape across different tasks underscores the ongoing evolution of AI technology [5].

Mark Chen, OpenAI's chief research officer, has described GPT-5 as "the most accurate and reliable AI model available on the market" [6]. Sam Altman, OpenAI's CEO, has gone a step further, calling GPT-5 a "legitimate PhD expert in any area," surpassing previous versions that were compared to college or high school students [7].

The rapid growth of ChatGPT's user base is a testament to the model's utility. It has grown four times larger than it was last year, and OpenAI expects it to reach 700 million weekly active users, up from 500 million in just five months [8].

People and teams are increasingly using ChatGPT to learn, create, and solve harder problems. From writing computer programs and preparing party invitations to navigating the health care system, GPT-5 offers a versatile and powerful tool [9].

This performance has set a record for the fastest-growing app user base [10]. As this story continues to develop, updates are expected.

In addition to these improvements, users can now interrupt the chatbot with follow-up queries in GPT-4o. This feature allows for more interactive and dynamic conversations [11].

As OpenAI continues to release new products and upgrades, the future of AI technology looks promising, with GPT-5 setting a new standard for intelligence, usability, and adaptability.
