GPT-3 (short for "Generative Pre-training Transformer 3") is the third version of the machine learning model for language processing GPT (Generative Pre-training Transformer) developed by OpenAI. It is a powerful tool for generating human-like text and performing various natural language processing tasks.


How ChatGPT 3 works

ChatGPT 3 is based on the Transformer architecture for neural networkspresented in the article "Attention is All You Need" by Vaswani et al. 2017. The Transformer architecture is well suited for natural language processing because it can process input sequences in parallel rather than sequentially, making it much faster than previous models such as recurrent neural networks (RNNs).

ChatGPT 3 takes a sequence of words as input and predicts the next word in the sequence. It does this by learning the statistical patterns and relationships between the words in the input text. For example, if the input text is "The cat sat on the", the model might predict that the next word is "mat" because it has learned that "on the" is often followed by a noun.

ChatGPT 3 can not only predict the next word in a sequence, but also generate entire text passages. To do this, it uses a method called "Sampling", where it predicts the next word in the sequence multiple times and then selects the word it thinks is the most likely based on the context of the input text. In this way, the model can produce coherent and naturally flowing text, just as a human would write it.

Main features and applications

One of the most important features of ChatGPT 3 is that it has been pre-trained on a very large dataset of texts written by humans. This pre-training allows the model to learn the structure and patterns of language in a general sense, so that it can perform well on a variety of natural language processing tasks without the need for task-specific training data.

ChatGPT 3 is significantly more powerful than its predecessor GPT-2 because it has a larger number of parameters and a larger dataset on which it has been trained. This has allowed it to achieve top performance in several natural language processing benchmarks and be used to develop various applications such as chatbots and language translation systems.

One of the most interesting aspects of ChatGPT 3 is its ability to "zero-shot" learning, which means that it can perform a new task without task-specific training data. This is possible because GPT-3 has learned the structure and patterns of the language so well during pre-training that it can adapt to new tasks relatively easily.
