Generative Pre-trained Transformer 4 (GPT-4) is a multimodal large language model created by OpenAI, and the fourth in its series of GPT foundation models. [1] It was launched on March 14, 2023, [1] and made publicly available via the paid chatbot product ChatGPT Plus, via OpenAI's API, and via the free chatbot Microsoft Copilot. [2]
The most recent of these, GPT-4, was released in March 2023. [11] Such models have been the basis for their more task-specific GPT systems, including models fine-tuned for instruction following—which in turn power the ChatGPT chatbot service. [1] The term "GPT" is also used in the names and descriptions of such models developed by others.
The 2023 GPT-4 was praised for its increased accuracy and as a "holy grail" for its multimodal capabilities. [15] OpenAI did not reveal high-level architecture and the number of parameters of GPT-4. Competing language models have for the most part been attempting to equal the GPT series, at least in terms of number of parameters. [16]
chatgpt.com. ChatGPT is a generative artificial intelligence chatbot [ 2 ][ 3 ] developed by OpenAI. Launched in 2022 based on the GPT-3.5 large language model (LLM), it was later updated to use the GPT-4 architecture. ChatGPT can generate human-like conversational responses and enables users to refine and steer a conversation towards a desired ...
Foundation model. A foundation model, also known as large AI model, is a machine learning or deep learning model that is trained on broad data such that it can be applied across a wide range of use cases. [ 1 ] Foundation models have transformed artificial intelligence (AI), powering prominent generative AI applications like ChatGPT. [ 1 ]
They said that GPT-4 could also read, analyze or generate up to 25,000 words of text, and write code in all major programming languages. [186] Observers reported that the iteration of ChatGPT using GPT-4 was an improvement on the previous GPT-3.5-based iteration, with the caveat that GPT-4 retained some of the problems with earlier revisions. [187]
GPT-2 was pre-trained on a dataset of 8 million web pages. [2] It was partially released in February 2019, followed by full release of the 1.5-billion-parameter model on November 5, 2019. [3] [4] [5] GPT-2 was created as a "direct scale-up" of GPT-1 [6] with a ten-fold increase in both its parameter count and the size of its training dataset. [5]
Glossary. v. t. e. Artificial general intelligence (AGI) is a type of artificial intelligence (AI) that matches or surpasses human cognitives capabilities across a wide range of cognitive tasks. This contrasts with narrow AI, which is limited to specific tasks. [ 1 ][ 2 ] AGI is considered one of the definitions of strong AI.
