ChatGPT (Chat Generative Pre-trained Transformer)

ChatGPT is a chatbot introduced by OpenAI in November 2022. It is based on the OpenAI GPT-3 family of large language models and is refined (learning transfer approach) with learning techniques and supervised reinforcement. ChatGPT was launched as a prototype on November 30, 2022 and quickly attracted attention for its detailed answers and precise answers in multiple knowledge areas. Its uneven material accuracy was considered a material defect. After the release of ChatGPT, OpenAI was valued at $29 billion. ChatGPT has been enhanced since GPT-3.5 with supervised learning and reinforcement learning. Both approaches used human trainers to improve model performance.

For supervised learning, the model was equipped with cats, which the trainers played on on both sides. : the user and AI Assistant. In the reinforcement phase, the trainers were the first to classify the responses generated by the model during the previous conversation. These rankings were used to create "reward models", where the model was refined using multiple iterations of Proximal Policy Optimization (PPO). Proximal Policy Optimization algorithms offer an economic advantage over regional trust policy optimization algorithms; eliminate many computationally intensive operations with greater efficiency. The models were trained in collaboration with Microsoft on their Azure supercomputing infrastructure. In addition, OpenAI continues to collect data from ChatGPT users that can be used to train and optimize ChatGPT. Users can vote for or against the responses they receive from ChatGPT; they can also fill the text field with an additional opinion by voting yes or no. Although the main function of the chatbot is to imitate a human interlocutor, ChatGPT is versatile.

For example, it has the ability to write and debug computer programs; compose music, TV films, cartoons and student essays; Answering test questions (sometimes, depending on the test, above the average of candidates); writing poems and song lyrics; emulate Linux; simulate an entire chat room; play games like noughts and crosses; and simulate ATM training data. ChatGPT contains man pages and information about Internet phenomena and programming languages such as bulletin board systems and the Python programming language.

Compared to its predecessor InstructGPT, ChatGPT tries to limit malicious and fraudulent responses. In one example, InstructGPT accepts the request “Tell me when Christopher Columbus arrived in the US in 2015”. To be honest, ChatGPT acknowledges the counterfactual nature of the question and formulates its answer as a hypothetical view of what would have happened if Columbus had arrived in the US in 2015, using information about Columbus' voyages and facts about the modern world , including the perception of Colombo's Unlike most chatbots, ChatGPT remembers previous signals given to it in the same conversation; Journalists have suggested that this could allow ChatGPT to be used as a personalized therapist.

To prevent offensive results from being presented and generated in ChatGPT, requests are filtered through the OpenAI Enterprise Moderation API and suggestions that are potentially racist or sexist are rejected. ChatGPT has many limitations. OpenAI acknowledges that ChatGPT "sometimes writes plausible but wrong or nonsensical answers". This behaviour is common with large speech patterns and is known as hallucination. The ChatGPT rewards model, designed in with human oversight in mind, can be over-optimized, affecting performance, aka Goodhart's Law. ChatGPT has limited knowledge of events after 2021. According to the BBC, as of December 2022, ChatGPT is no longer authorized to "express political opinions or engage in political activity".

However, research suggests that ChatGPT exhibits a pro-environmental and libertarian bias when asked to comment on the policy statements of two mainstream voting apps. During training on ChatGPT, reviewers preferred longer answers regardless of actual understanding or content of . The training data is also subject to an algorithmic error that can be revealed when ChatGPT responds to requests, including people's handles. On one occasion, ChatGPT spawned a rap claiming that female and black scientists were inferior to white and male scientists.

Google internally expressed alarm at the unexpected strength of ChatGPT and the newly discovered potential of large language models to disrupt the search engine business, and CEO Sundar Pichai "upended" and reassigned teams within multiple departments to aid in its artificial intelligence products and Microsoft Bing was planning to add optional ChatGPT functionality into its public search engine, possibly around March 2023.

Is OpenAI owned by Elon Musk?

Elon Musk is the founder of Tesla, SpaceX, and several other start-ups. He has made large contributions to OpenAI, including donating $10 million in 2016. However, he is not the sole owner of the company.
