v. t. e. 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".

Auto-GPT. Auto-GPT is an open-source " AI agent " that, given a goal in natural language, will attempt to achieve it by breaking it into sub-tasks and using the Internet and other tools in an automatic loop. [ 1] It uses OpenAI 's GPT-4 or GPT-3.5 APIs, [ 2] and is among the first examples of an application using GPT-4 to perform autonomous tasks.
GPT-4o ( GPT-4 Omni) is a multilingual, multimodal generative pre-trained transformer designed by OpenAI. It was announced by OpenAI's CTO Mira Murati during a live-streamed demo on 13 May 2024 and released the same day. [ 1] GPT-4o is free, but with a usage limit that is 5 times higher for ChatGPT Plus subscribers. [ 2]
