GPT

Generative Pre-trained Transformer (GPT) is a type of large language model (LLM) and a prominent framework for generative artificial intelligence. It is an artificial neural network used in natural language processing, based on the transformer deep learning architecture, pre-trained on large datasets of unlabeled text, and capable of generating novel human-like content.
== History ==
The first GPT model was introduced in 2018 by OpenAI. Since then, OpenAI has released a series of increasingly capable GPT foundation models, each sequentially numbered in the "GPT-n" series. These models have shown significant improvements in capabilities due to increased size (number of trainable parameters) and more extensive training.
=== GPT-1 (2018) ===
GPT-1, released in June 2018, marked the beginning of the GPT era. With 117 million parameters, it demonstrated the potential of large-scale pre-training followed by fine-tuning for specific tasks. GPT-1 introduced several key innovations, including large-scale pre-training, fine-tuning, and transfer learning.
=== GPT-2 (2019) ===
In November 2019, OpenAI introduced GPT-2, a large language model with 1.5 billion parameters. GPT-2 significantly enhanced text generation capabilities and showcased improved natural language understanding across various domains.
=== GPT-3 (2020) ===
June 2020 saw the arrival of GPT-3, a foundational large language model with 175 billion parameters. GPT-3's profound advancements in natural language understanding and generation capabilities set new benchmarks in the field of AI, enabling a wide range of applications from conversational chatbots to content creation.
=== GPT-4 (2023) ===
The most recent iteration, GPT-4, was released in March 2023. OpenAI declined to publish the size or training details of this model, citing competitive and safety considerations.
== Products and Services ==
