Revolutionized Language Model: GPT-5 Features Improved Memory Capabilities and Accuracy by OpenAI
OpenAI has made a significant leap in artificial intelligence (AI) with the release of GPT-5, the latest addition to their family of AI models. This groundbreaking model, launched on August 7, 2025, is set to be the new default for ChatGPT users, both free and paid [1][4].
GPT-5 represents a significant advancement from its predecessors, combining the strong reasoning capabilities of OpenAI's "o" series models with the faster response times of the GPT-series models. This unified model design enables GPT-5 to tackle a broader range of complex tasks, such as generating software applications, managing calendars, and creating research briefs on behalf of users [1][4].
One of the key differences between GPT-5 and earlier models is its substantially improved reasoning, coding quality, and user experience. GPT-5 excels at complex, end-to-end coding tasks with minimal prompting, demonstrating superior performance on coding benchmarks [5]. It is also more agentic, meaning it can take initiative and perform tasks as an intelligent assistant rather than merely responding to prompts, positioning it closer to an AI agent than a chatbot [1][2].
Other notable improvements include a real-time router that autonomously decides when to give fast answers or undertake deeper "thinking" for more thorough responses, simplifying the user experience [1][4]. GPT-5 also demonstrates higher safety standards with fewer hallucinations and more honest communication about its capabilities and actions [5].
The GPT-5 Pro variant, aimed at enterprise and educational users, offers extended reasoning capabilities for more reliable and detailed answers [3][4]. GPT-5 is not only available in ChatGPT but also integrated into tools like GitHub Copilot, reinforcing its role as a collaborative coding assistant [2][5].
The growth of the ChatGPT user base has been impressive, with an estimated 500 million weekly active users as of April 2025. Despite the delay in the release of GPT-5, this growth continued during the delay period [3]. OpenAI predicts that the number of weekly active ChatGPT users could increase to 700 million in the near future [1].
Users can personalise the interface by selecting the chat colour and one of four communication styles: Cynic, Robot, Listener, or Nerd. Via API, users can choose between three versions of the model: GPT-5, GPT-5 mini, or GPT-5 nano [1].
OpenAI's CEO, Sam Altman, stated that the transition to GPT-5 will make using ChatGPT "so impressive" that users won't want to go back to previous versions [2]. The delay in the release of GPT-5 did not appear to impact the growth of the ChatGPT user base, making this achievement all the more noteworthy [3].
GPT-5 fabricates facts less often and communicates more clearly when it cannot answer a question, contributing to its increased reliability and safety [1]. With its advanced capabilities, GPT-5 is positioned as OpenAI’s most intelligent, fastest, and most capable model to date, aiming at outperforming humans in many economically valuable tasks and advancing toward artificial general intelligence (AGI) [1][4].

The unified model design of GPT-5 allows it to tackle complex tasks that previous models couldn't, such as generating software applications, managing calendars, and creating research briefs.
In addition to its improved reasoning and coding capabilities, GPT-5 exhibits higher safety standards with fewer hallucinations and more honest communication about its actions, contributing to its increased reliability and safety.
