OpenAI’s GPT series comprises a family of large language models designed for generating text and performing natural language processing tasks. GPT (Generative Pre-trained Transformer) models are based on a decoder-only transformer architecture, optimized for tasks like text completion, summarization, translation, and question answering.
The series began with GPT-1, which demonstrated the power of unsupervised pretraining for NLP tasks. GPT-2 expanded this approach with a much larger model, showcasing capabilities like coherent text generation and contextual understanding. GPT-3 further scaled up to 175 billion parameters, enabling highly versatile applications such as code generation and chatbot interactions. GPT-4, the latest in the series, introduced advancements in multi-modal capabilities, handling both text and images.
The GPT series has been widely adopted due to its versatility and scalability. OpenAI provides API access, making these models accessible for integration into various applications without the need for extensive computational resources or expertise in training.
