ChatGPT (Chat Generative Pre-trained Transformer) [1] is a large-scale language generation model launched on November 30th, 2022 by OpenAI. The model is trained on a massive dataset of human-generated text and can generate human-like text in a wide range of styles and formats.

Training

ChatGPT is based on OpenAI's GPT-3.5, an upgraded version of GPT-3, the A.I. text generator [2]. The GPT3.5 language model was initially built from web content and other publicly available sources [3]. Supervised machine learning techniques were then used to build the model. Supervised learning refers to a class of systems and algorithms that determine a predictive model using data points with known outcomes. The model is learned by training through an appropriate learning algorithm (such as linear regression, random forests, or neural networks) that typically works through some optimization routine to minimize a loss or error function. [4]. By using Reinforcement Learning from Human Feedback, human trainers played the role of both the user and the AI agent—generating a variety of responses to any given input and then evaluating and ranking them from best to worst [5]. This data was used to train a reward model.

An OpenAI reinforcement learning algorithm called Proximal Policy Optimization was used to fine-tune results [6]. Proximal Policy Optimization balances ease of implementation, sample complexity, and ease of tuning to compute an update at each step that minimizes the cost function while ensuring the deviation from the previous policy is relatively small [7]. The Transformer architecture used in ChatGPT is a type of neural network that is particularly well-suited to natural language processing tasks. The architecture is based on the idea of self-attention, which allows the model to weigh the importance of different words in a sentence when generating new text. This allows the model to generate text that is more coherent and relevant to the input. [8]

Capabilities

ChatGPT's main function is to mimic a human conversation. However, it can perform other functions as well. It has the ability to generate responses in a chatbot or virtual assistant, brainstorm content ideas on keywords or topics, create personalized communications such as email responses or product recommendations, create marketing content like blog posts or social media updates, translate text from one language to another, generate shorter summaries of long documents, and write and debug computer programs [9].

Reception and Interest

After launching in November 2022, ChatGPT ________________________ (add some stat about popularity). ** add a sentence about companies that are interested in being a part of / acquiring open AI for chatGPT **. Buzzfeed Inc Chief Executive Jonah Peretti spoke about relying on ChatGPT creator OpenAI to enhance its quizzes and personalize some content for its audiences [10]. In January 2023, Microsoft confirmed it was making making a "multibillion dollar" investment in OpenAi and said it plays to expand the partnership as part of a greater effort to add more artificial intelligence to its suite of products. [11] In December 2022, Google internally expressed alarm at the unexpected strength of ChatGPT and the newly discovered potential of large language models to be a serious thread to its main search business. [12]. Sunday Pichai, Google's Chief executive, upened the work of many teams to respond to the threat that ChatGPT poses [13].
