ChatGPT : chatbot launched by OpenAI

 Launched by OpenAI in November 2022, ChatGPT is a chatbot. It is built off of the GPT-3.5 family of massive language models via OpenAI, and it has been enhanced using supervised and reinforcement learning methods.

On November 30, 2022, ChatGPT was released as a prototype. It soon gained popularity for its thorough responses and clear responses in a wide range of topics. Its uneven factual accuracy was found to be a major flaw.

Elon Musk has worked with OpenAI in the past, but he is not currently involved in its daily operations or decision-making. OpenAI is an independent organization.

A sizable language model is ChatGPT (LLM). Massive volumes of data are used to train large language models (LLMs) to precisely anticipate what word will appear next in a phrase.

It was shown that the language models could perform more tasks when there was more data available.

Similar to autocomplete, but on a mind-boggling size, LLMs predict the next word in a string of words in a sentence as well as the following sentences.

They are able to produce paragraphs and full pages of text thanks to this skill.

But LLMs have a drawback in that they frequently fail to comprehend precisely what a person wants.

And with the aforementioned Reinforcement Learning with Human Feedback (RLHF) training, ChatGPT advances the state of the art in this area.

GPT-3.5 was once educated on big quantities of information about code and data from the internet, which include sources like Reddit discussions, to assist ChatGPT research speak and reap a human fashion of responding. ChatGPT was once additionally educated the usage of human remarks (a approach known as Reinforcement Learning with Human Feedback) so that the AI discovered what people anticipated when they requested a question. Training the LLM this way is innovative due to the fact it goes past clearly education the LLM to predict the subsequent word.

The engineers who built ChatGPT employed contractors (called labelers) to price the outputs of the two systems, GPT-3 and the new InstructGPT (a “sibling model” of ChatGPT).


Based on the ratings, the researchers got here to the following conclusions:

“Labelers significantly prefer InstructGPT outputs over outputs from GPT-3.

InstructGPT models show improvements in truthfulness over GPT-3.

InstructGPT shows small improvements in toxicity over GPT-3, but not bias.”

ChatGPT is in particular programmed no longer to furnish poisonous or dangerous responses. So it will keep away from answering these sorts of questions.

Another challenge is that due to the fact it is skilled to furnish solutions that experience proper to humans, the solutions can trick people that the output is correct.

Many users observed that ChatGPT can furnish fallacious answers, inclusive of some that are wildly incorrect.
