GPT-5 is the fifth and current flagship model of the generative pre-trained transformers (GPT) from OpenAI<\/a>. It was introduced on August 7, 2025 and represents a further development of the predecessor models, including GPT-4 and its variants. GPT-5 is a multimodal large language model<\/a> that can process and generate text, images and audio content.<\/p>\n

Definition and architecture of GPT-5<\/h2>\n

GPT-5 is a comprehensive system designed to integrate both rational and non-rational functions under a unified user interface. A key innovation is the real-time router, which automatically decides whether to use a fast, high-throughput model for routine queries or a more in-depth \u201ethinking model\u201c for complex thought processes. This eliminates the need for users to manually switch between specialized models.<\/p>\n

The model was trained from scratch as a native multimodal system, meaning that it was developed simultaneously with different data modalities such as text and images, rather than building on already trained speech or vision models. The training process included unsupervised pre-training, supervised fine-tuning and reinforcement learning using human feedback.<\/p>\n
