Latest AI advancement by OpenAI: An overview of GPT-5, their new model
In an exciting development, OpenAI has unveiled its latest and most advanced language model, GPT-5. This AI model, announced and released on August 7, 2025, is now available on a range of platforms, including browsers on PC or Laptop, mobile apps on iOS and Android devices, and the official ChatGPT app for Mac.
One of the key features of GPT-5 is its smarter task routing. The model automatically selects the best reasoning model or standard GPT style for the task, eliminating the need for users to pick manually between reasoning or speed-focused models. This real-time routing makes GPT-5 more efficient and user-friendly.
GPT-5 also offers four preset chatbot personalities—cynic, robot, listener, and nerd—to make conversations more natural and context-appropriate. This feature allows users to tailor their interactions, making the AI more adaptable to different situations.
Another significant improvement is the reduction in hallucinations. GPT-5 significantly lowers the rate of generating factually incorrect or fabricated information compared to earlier models. It is about 45% less likely to produce factual errors than GPT-4 and about 80% less likely than the OpenAI o3 model.
GPT-5 is also faster and more efficient in its thinking. It uses 50-80% fewer output tokens to perform better across capabilities like visual reasoning, coding, and scientific problem-solving while running faster. This speed and efficiency make GPT-5 a powerful tool for complex tasks.
In terms of coding and debugging capabilities, GPT-5 excels, particularly in complex front-end generation and debugging larger repositories. It is the strongest OpenAI coding model to date.
GPT-5 is also more reliable on complex, open-ended questions, with about 80% fewer factual errors on critical benchmarks. It is also trained to better recognize its own limitations, enhancing trustworthiness especially in domains like health.
For developers, GPT-5 offers customizable reasoning and verbosity parameters, allowing API users to control the amount of reasoning effort (from minimal to high) and answer length (low to high verbosity), optimizing for speed or quality depending on the task.
GPT-5 also demonstrates better agentic and real-world task performance, chaining together actions to accomplish complex tasks more reliably. However, its navigation of certain websites shows mixed results compared to rival AI models.
Early feedback from companies such as Amgen and Morgan Stanley indicates higher accuracy, reliability, and quality of outputs, reflecting GPT-5’s value in business applications.
Subscribers to paid tiers of ChatGPT such as Plus, Pro, and Team have access to the model picker, allowing them to select previous and current versions of the model, including the GPT-4 model. Free users will be switched to GPT-5 mini when their main use ends.
The Voice mode is coming to all tiers, and users can customize the responses to this. Additionally, users can alter the color scheme of the interface to personalize their experience.
In summary, GPT-5 is distinguished by its smarter task routing, personality options, sharp reduction in hallucinations, improved coding and reasoning abilities, and flexible developer controls, making it OpenAI’s most advanced and useful language model yet. This AI model is set to revolutionize the way we interact with AI, offering a more natural, less 'AI-like' writing style and greater reliability in its responses.
Artificial-intelligence advancements in GPT-5 are evident in its ability to choose the best reasoning model or standard GPT style for tasks, enhancing efficiency and user-friendliness.
The integrated artificial-intelligence within GPT-5 allows it to excel in complex tasks, particularly in coding, debugging, and complex front-end generation.
