About:

• The tool has been developed by OpenAI, a research institute founded in 2015.
• This tool ‘knew’ every topic under the sun; it could answer questions and carry on a conversation.
• This tool interacts with humans in natural language and is impressive because aside from answering general queries, it has many other functions.
• ChatGPT is much more than a chat bot.
  • For example, you can ask it to write a program or even a simple software application.
• It can also do creative tasks such as writing a story. It can explain scientific concepts and answer any question that needs factual answers.

Language Model:

• ChatGPT is what is called a Language Model, rather than a chat bot.
• A language model is a software that prints out a sequence of words as output that are related to some words given as input with appropriate semantic relation; in practical terms, it means that it can perform tasks like answering questions and carrying on a conversation with humans.
• It is often used in natural language processing (NLP) applications, such as speech recognition, automatic translation, and text generation.
• There are a few other language models like:
  • BERT (Bidirectional Encoder Representations from Transformers) from Google.

Standard Techniques:

• The accuracy of ChatGPT or any language model can be measured using standard techniques.
• One such technique is “Recall-Oriented Understudy for Gisting Evaluation” or the ROUGE metric which compares ChatGPT’s output of content against a standard expected content and measures the overlap as success percentage.
• For language models like GPT that are also used in translation, another metric called the BLEU metric (Bilingual Evaluation Under Study) is employed; this metric compares overlap in translated content with a standard translation.

Neural Network:

• It is also a neural network.
• A neural network can be thought of as a large network of computers that can fine tune its output of words based on the feedback given to it during stages of training: this training process and the technology together are called Reinforcement Learning.
• The input data is typically huge corpus of text.

OpenAI:

• OpenAI is a research institute and company that focuses on developing artificial intelligence technology in a responsible and safe way.
• It was founded in 2015 by a group of entrepreneurs and researchers, including Elon Musk, Sam Altman, and Greg Brockman.
