GPT-5

GPT-5 is the latest generation of OpenAI’s large language model (LLM), which powers ChatGPT and is also available to developers via an API. Compared to previous versions, it offers more advanced logical reasoning, multimodal processing (text, images), and a significantly longer context window, allowing it to handle more complex tasks and longer documents at once. Models of this generation are used not only in chat interfaces but also in agent systems, where they independently plan and execute multi-step tasks.
