GPT is a family of artificial intelligence models developed by OpenAI for language, reasoning, coding, multimodal tasks, and tool use.
What is GPT?
GPT stands for Generative Pre-trained Transformer. It is not one model but a family that has evolved through multiple generations with different capabilities, speeds, prices, and access methods.
How does GPT work?
GPT models process inputs as tokens and generate outputs based on patterns learned during training. Selected versions can reason through complex problems, understand images or audio, call tools, and complete multistep workflows.
Where is GPT used?
The family powers capabilities in ChatGPT, the OpenAI API, and third-party applications for writing, research, customer support, data analysis, coding, and agents. Context limits, modalities, and pricing depend on the exact model.
Strengths and limitations
GPT offers a wide range of models and strong integration with tools and applications. However, outputs may be inaccurate, training details are only partly disclosed, and models or prices can change over time.
In short
GPT names OpenAI’s model family, while ChatGPT is a product that can use different models. The two terms are related but not interchangeable.
