OpenAI made ChatGPT (Generative Pre-trained Transformer), an AI-powered chatbot. It can have conversations like a person, answer questions, write content, solve problems, and help with a lot of other things because it is based on advanced language models. The system uses machine learning to understand the situation, keep the conversation going, and come up with answers that sound natural and helpful. ChatGPT is different from regular search engines because it takes information from many sources and presents it in a conversational way. It can talk about deep subjects, write creative pieces, fix code, translate languages, and even talk about philosophy.
How ChatGPT Models Have Changed Over Time
The current standard is GPT-4o.
As of April 30, 2025, GPT-4 will no longer be available on ChatGPT and will be completely replaced by GPT-4o. This is a big step forward for the platform. The GPT-4o model and its family, which are also known as the “o models,” are OpenAI’s newest flagship models. They were built from the ground up to be multimodal. Updates to GPT-4o have made it easier to use and more intuitive. GPT-4o is easier to use, more creative, and more collaborative. It also follows instructions better and handles coding tasks more smoothly. The model now talks to you in a way that is clearer and more natural, with shorter, less cluttered answers.
