GPT-4

"some have predicted that GPT-4 will contain over 100 trillion parameters — nearly 600 times as many as GPT-3"
GPT-4 (Generative Pre-trained Transformer 4) is a hypothetical version of the GPT (Generative Pre-trained Transformer) language model that has not yet been released. The GPT series of language models are developed by OpenAI and are known for their ability to generate human-like text, perform language translation, and complete a variety of other language tasks.
As of September 2021, the most recent version of the GPT model is GPT-3 (Generative Pre-trained Transformer 3), which has 175 billion parameters. It is possible that a future version of the GPT model, such as GPT-4, may have significantly more parameters than GPT-3. The number of parameters in a language model is a measure of its capacity and complexity, and a larger number of parameters can enable a model to learn more complex relationships between words and generate more realistic and varied text. However, it is worth noting that the size of a model is not the only factor that determines its performance, and there may be other improvements or changes made to the model in addition to increasing the number of parameters.
