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]
Although decoder-only GPT-1 was introduced in 2018, it was GPT-2 in 2019 that caught widespread attention because OpenAI at first deemed it too powerful to release publicly, out of fear of malicious use. [14] GPT-3 in 2020 went a step further and as of 2024 is available only via API with
OpenAI's GPT-n series Model Architecture Parameter count Training data Release date Training cost GPT-1: 12-level, 12-headed Transformer decoder (no encoder), followed by linear-softmax. 117 million BookCorpus: [39] 4.5 GB of text, from 7000 unpublished books of various genres.

GPT-4o has knowledge up to October 2023, [15] [16] but can access the Internet if up-to-date information is needed. It has a context length of 128k tokens [ 15 ] with an output token limit capped to 4,096, [ 16 ] and after a later update (gpt-4o-2024-08-06) to 16,384.
OpenAI's chatbot, ChatGPT, was released in November 2022, is based on GPT-3.5 and GPT-4 large language models. Celeste Biever wrote in a Nature article that "ChatGPT broke the Turing test". [ 9 ]
OpenAI's GPT-4 model was released on March 14, 2023. Observers saw it as an impressive improvement over GPT-3.5, with the caveat that GPT-4 retained many of the same problems. [ 96 ] Some of GPT-4's improvements were predicted by OpenAI before training it, while others remained hard to predict due to breaks [ 97 ] in downstream scaling laws .
On March 30, 2023, AutoGPT was released by Toran Bruce Richards, the founder and lead developer at video game company Significant Gravitas Ltd. [3] AutoGPT is an open-source autonomous AI agent based on OpenAI's API for GPT-4, [4] the large language model released on March 14, 2023. AutoGPT is among the first examples of an application using ...
Generative Pre-trained Transformer 4 (GPT-4) is a multimodal large language model trained and 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]
