GPT
Generative Pre-training Transformer, often abbreviated as GPT, refers to a class of machine learning models that are used to generate natural language text. Developed by OpenAI, a leading research organization in the field of artificial intelligence, these models are at the cutting edge of AI technology.
Origins and Development
The development of GPT models was inspired by earlier work on transformer-based language models, which were introduced in a 2017 paper by Vaswani et al. entitled “Attention is All You Need”. The paper showed that a transformer model, which uses a mechanism called “attention” to understand the context of words in a sentence, could outperform other state-of-the-art models on a range of language tasks.
OpenAI built on this idea with the introduction of GPT-1 in 2018. This model was pre-trained on a large corpus of text data, which allowed it to learn a wide range of language patterns and structures. The model could then generate text that was remarkably fluent and coherent, although it still had limitations in terms of its understanding and generation of content.
The GPT model underwent further development with the introduction of GPT-2 in 2019 and GPT-3 in 2020. Each new iteration of the model was larger and more powerful than the last, with GPT-3 containing 175 billion parameters, making it the largest language model of its kind at the time of its release.
How GPT Works
The GPT models are based on the transformer architecture, which uses attention mechanisms to understand the context of words in a sentence. The models are trained on a large corpus of text data, which allows them to learn a wide range of language patterns and structures. This pre-training phase is unsupervised, meaning that the models learn to understand and generate language by recognizing patterns in the data, rather than being explicitly told what to do.
