ChatGPT is a generative artificial intelligence chatbot developed by OpenAI and launched in 2022. It is currently based on the GPT-4o large language model (LLM). ChatGPT can generate human-like conversational responses and enables users to refine and steer a conversation towards a desired length, format, style, level of detail, and language. [2]
For starters, ChatGPT-4 is multimodal (working with both imagers and text) and more “steerable” than ChatGPT-3.5 in that it can take multiple prompts in greater numbers, which allows it to ...
Generative Pre-trained Transformer 3 (GPT-3) is a large language model released by OpenAI in 2020.. Like its predecessor, GPT-2, it is a decoder-only [2] transformer model of deep neural network, which supersedes recurrence and convolution-based architectures with a technique known as "attention". [3]
The release of ChatGPT led to an uptick in LLM usage across several research subfields of computer science, including robotics, software engineering, and societal impact work. [17] In 2024 OpenAI released the reasoning model OpenAI o1 , which generates long chains of thought before returning a final answer.
The creators of ChatGPT have revealed a new model they say is even more powerful than that already viral system. The new tool, GPT-4, is available in some versions of ChatGPT and to paying ...
The system then responds with an answer within seconds. ChatGPT reached 1 million users 5 days after its launch. [255] [256] As of 2023, ChatGPT Plus is a GPT-4 backed version of ChatGPT [257] available for a US$20 per month subscription fee [258] (the original version is backed by GPT-3.5). [259]
Both text-davinci-003 and ChatGPT were released in November 2022, with both building upon text-davinci-002 via reinforcement learning from human feedback (RLHF). text-davinci-003 is trained for following instructions (like its predecessors), whereas ChatGPT is further trained for conversational interaction with a human user.

In 2022, a chatbot based on GPT-3, ChatGPT, became unexpectedly popular, [36] triggering a boom around large language models. [37] [38] Since 2020, Transformers have been applied in modalities beyond text, including the vision transformer, [39] speech recognition, [40] robotics, [41] and multimodal. [42]
