Audio episode : GPT-5 — what’s new 8 min ▶ Listen GPT-5: The Future of AI by OpenAI – Review, Pricing & Alternatives GPT-5 , OpenAI’s latest creation, is now entering the field of large LLM models. This comprehensive model brings together and surpasses all AI models available worldwide. It includes 4o models, OpenAI’s O-series reasoning, autonomous agents, and strong mathematical skills. Built to be more reliable and better suited to professional tasks, this tool is changing the way humans and AI work together. Remember: this is a major change, not just a simple update. ➥ So, what’s GPT-5? GPT-5 is the 5th generation of generative models pre-trained by OpenAI. It’s the most powerful LLM model available in ChatGPT, and it’s been officially available since August 7, 2025. It uses the GPT architecture, while adding improvements from reasoning-focused models. A long-term research project This model is the culmination of OpenAI’s research into logic, sequential thought processes, and multi-format design. It is, in fact, the most powerful model ever developed by the company. In addition, it brings significant improvements to all components of ChatGPT, whether it be the API or the various tools for developers. (Context window also expanded to 256,000 tokens) ➥ How does GPT-5 work? This model functions as a coordinated system, capable of automatically providing the best version of ChatGPT for your request. There is no longer a need to manually select a specific model. It is faster and more accurate, especially for specific tasks such as writing, programming, or medical research. Safety first One of its new features is “secure completion.” This feature allows the ChatGPT assistant to give the most useful answer possible while respecting clear security limits. It can also explain why it cannot help you in certain cases. (This helps to understand the limitations of AI.) Reasoning and contextual understanding GPT-5’s reasoning abilities have been greatly improved. It can now solve more difficult problems, especially those that require multiple steps of reasoning. Initial tests suggest that it can solve complex problems, almost like someone with a PhD. Improved multimodal capabilities Also, it has multi-format features, handling text, images, sounds, and videos. Of course, it can easily connect to tools like Sora for video creation and Whisper for audio transcription. Integrated autonomous agents GPT-5 includes enhanced AI agent capabilities. This means it can perform tasks on its own. You can now entrust it with complex missions. These range from planning a complete trip with multiple stops to managing different tasks across multiple software applications. The GPT 5 model also offers good integration with commonly used services such as Gmail , Google Calendar, and Google Contacts. The magic of real-time learning While previous language models relied solely on previous training, GPT-5 incorporates new data from real-time user queries. This method is also known as “computing at test time.” This ability to instantly assimilate and use new information marks an important development. It makes exchanges even more accurate and context-appropriate. Watch the official OpenAI conference ➥ What’s new in GPT-5? In-depth reasoning GPT-5 no longer simply responds: it deploys multi-step reasoning, structures its responses, and justifies its choices, making exchanges much more relevant and professional. This ability to “think in steps” revolutionizes its use in business and education. Advanced multimodality The new model processes text, images, and data more naturally and is geared toward the future integration of video. GPT-5 is very good at simultaneously analyzing different types of documents, facilitating visual workflows and complex problem solving. Drastic reduction in hallucinations Reliability is one of the strengths of this powerful model, with a factual error rate up to 45% lower than the previous version, and “safe completions” mechanisms to avoid misleading or inaccurate responses. Expanded context window GPT-5 now handles up to 256,000 tokens , allowing it to assimilate long exchanges, large PDFs, or large blocks of code without losing track of the conversation. Code performance The model has established itself as a valuable programming collaborator, able to write, review, and correct complex projects in record time, with superior performance on benchmark tests and a significant reduction in error rates. Customization, voice, and education Tone selection, visual customization, improved voice modes, and above all “Study Mode,” an interactive mode designed for learning, make GPT-5 a comprehensive tool that can be adapted to each user profile. ➥ 4 new chat personalities This is brand new! You can now choose a character from the ChatGPT interface. The new feature lets you chat with conversation styles that are more suited to your preferences. Cynic: In Cynic mode, GPT-5 adopts a sharp and clear-eyed tone, dismantling preconceived ideas and highlighting blind spots with measured irony—useful for testing the strength of an argument or spotting the “hype” behind a claim. Robot: In Robot mode, GPT-5 responds in a factual, concise, and structured manner, with a neutral style similar to technical documentation—ideal for procedures, checklists, and no-frills answers. Listener: The Listener mode prioritizes empathy, reformulates the need, and, when necessary, asks clarifying questions in order to provide context-aware answers that are genuinely useful in the exchange. Nerd: The Nerd mode focuses on precision, technical details, and references—perfect for delving deeper into a topic, comparing approaches, or exploring nuances and edge cases. ➥ Pros and cons GPT 5 is one of the most effective artificial intelligence models currently available. However, like any technological device, it has significant strengths and aspects that could be seen as limitations. Enhanced Reliability : This model reduces factual errors and “hallucinations,” providing more accurate and trustworthy answers. Improved Multimodality : It can process and generate information from text, images, audio, and video, greatly expanding application areas.
