ChatGPT is a NLP (natural language processing) model chatbot developed by OpenAI based on the GPT-3 family of large language models and is fine-tuned with both supervised & reinforcement learning techniques. GPT-3 stands for “Generative Pre-trained Transformer 3”. This project is currently in beta testing and launched on November 30, 2022. 

The ChatGPT can be used for customer service, personal assistant applications, automated customer support, and many more. You can access ChatGPT simply by visiting chat.openai.com and creating an OpenAI account. Currently it's FREE considering its  in “research preview” time period and open for users to try out and provide feedback but as of Feb 1st there is  also a paid subscription version called ChatGPT Plus.

GPT-3 was trained using a combination of supervised learning and Reinforcement Learning through Human Feedback (RLHF). Supervised learning is the stage where the model is trained on a large dataset of text scraped from the internet. The reinforcement learning stage is where it is trained to produce better responses that align with what humans would accept as being both human-like and correct. It's not an easy task for ChatGPT to replace Google in the near future as there are many differences between a chatbot and a Search Engine.

The basic difference is that a chatbot is a language model created with the purpose of holding a conversation with the end user. A search engine indexes web pages on the internet to help the user find the information they asked for. ChatGPT does not have the ability to search the internet for information.

 ChatGPT Use-Cases:

ChatGPT can be applied to a range of NLP applications, such as: Generating Text, Dialogue Generation, Language Translation, Text Summarization, Text Classification, Question Answering, Text Completion etc.

●  Language Translation: Useful for chatbot or customer service applications.

● Generating Text: This can be used for writing, content creation, and other applications.

●Dialogue Generation: Making it useful for building chatbots and virtual assistants.

● Text Classification: Useful for sentiment analysis, intent recognition, and other NLP applications.

● Text Summarization: Useful for news articles, long documents, and other texts.

● Text Completion: Useful for predictive text input and other applications.

● Question Answering: Useful for chatbots and customer service applications.
