ChatGPT (Generative Pre-trained Transformer) is an advanced chatbot that is based on artificial intelligence (AI) and developed by the US company OpenAI was developed. It simulates human-like conversations and processes requests in natural language. The technology behind this are so-called Large Language Models (LLMs), trained with immense amounts of data from the Internet.
Functionality and technical basis
ChatGPT is based on a neural network that works according to the Transformer model. This enables the system to understand the complex relationships between words in a text and to generate new, coherent and context-related content based on this. The algorithm analyzes the previous context of a conversation in order to create suitable answers. It not only processes input in text form, but since newer versions such as GPT-4o, it can also understand and generate audio and image content.
The training is based on billions of words and text passages as well as other data such as images, audio and video in order to learn patterns and contexts. This enables ChatGPT to answer questions, compose, translate, summarize, paraphrase and correct texts. The models such as GPT-3.5, GPT-4 and the latest version GPT-5 (as of August 2025) are continuously being developed to improve accuracy and the range of applications.
