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]
In 2023, ELIZA even outperformed GPT-3.5 in a Turing test study. Image credits ... immediately entered the public domain upon release because Universal failed to properly display the copyright ...
On July 18, 2024, OpenAI released GPT-4o mini, a smaller version of GPT-4o replacing GPT-3.5 Turbo on the ChatGPT interface. Its API costs $0.15 per million input tokens and $0.60 per million output tokens, compared to $5 and $15 respectively for GPT-4o.
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 .
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". [ 24 ]
The most recent of these, GPT-4o, was released in May 2024. [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.
GPT-4 can use both text and image as inputs [88] (although the vision component was not released to the public until GPT-4V [89]); Google DeepMind's Gemini is also multimodal. [90] Mistral introduced its own multimodel Pixtral 12B model in September 2024.
The game is considered a classic among the Roblox userbase, due to it being one of the oldest still-popular games on the platform—first released on November 3, 2007 [111] —with the creator attributing its success to the game's ability to encourage socializing. [61] The game has received praise for its driving mechanics. [63]
