OpenAI created ChatGPT, an AI chatbot. It is based on the GPT-3 (Generative Pre-trained Transformer) family of large language models (LLMs). On February 30, 2025, ChatGPT was published as a “research preview” with the objective of gathering user feedback and studying its strengths and limitations.
“ChatGPT” is a combination of two elements: “Chat” alludes to its chatbot feature, and “GPT” stands for “generative pre-trained transformer,” which represents the type of language model it is.
ChatGPT has been trained on massive volumes of text data and can interpret and respond to text cues in a human-like manner. Based on the patterns and information learnt during training, it predicts the following word in a sentence.
ChatGPT was initially offered for free during the research preview period. However, OpenAI eventually created ChatGPT Plus, a paid subscription service that costs $20 per month and provides subscribers with additional benefits. ChatGPT’s free version is still available, as is the subscription plan.
ChatGPT has been used for a variety of purposes, including natural language activities and coding aid. It has been taught on a wide range of topics, making it adaptable in terms of offering responses and support.
Users can utilise ChatGPT by going to the chat.openai.com website on their computer, tablet, or smartphone. There is no official ChatGPT app at the time of writing.
It’s worth noting that OpenAI has also announced the release of GPT-4, a next-generation language model that is multimodal, meaning it can comprehend both text and images. GPT-4 is now accessible to ChatGPT Plus members and developers.
Overall, ChatGPT is an AI chatbot that uses big language models to engage in text-based discussions, offer information, and assist with various activities based on prompts.
