OpenAI o3 is a reflective generative pre-trained transformer (GPT) model developed by OpenAI as a successor to OpenAI o1. It is designed to devote additional deliberation time when addressing questions that require step-by-step logical reasoning. [1] [2] OpenAI released a smaller model, o3-mini, on January 31st, 2025.

OpenAI o1 is a reflective generative pre-trained transformer (GPT). A preview of o1 was released by OpenAI on September 12, 2024. o1 spends time "thinking" before it answers, making it better at complex reasoning tasks, science and programming than GPT-4o. [1] The full version was released to ChatGPT users on December 5, 2024. [2]
OpenAI has unveiled a preview of its new o3 reasoning models, which, CEO Sam Altman said immodestly, begin the “next phase” of AI. The models, announced Friday, did so well on a prominent ...
OpenAI unveils latest AI model, customizable GPTs and digital store. Samantha Kelly, CNN. November 6, 2023 at 3:57 PM. The technology behind viral AI chatbot ChatGPT just got a whole lot smarter.
Generative Pre-trained Transformer 2 (GPT-2) is a large language model by OpenAI and the second in their foundational series of GPT models. 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]
Last December, OpenAI said it was testing reasoning AI models, o3 and o3 mini, indicating growing competition with rivals such as Alphabet's Google to create smarter models capable of tackling ...
Bengio said that stronger safety tests and regulatory oversight are needed for advanced AI models. OpenAI's new o1 model is better at scheming — and that makes the "godfather" of AI nervous.
Generative Pre-trained Transformer 1 (GPT-1) was the first of OpenAI's large language models following Google's invention of the transformer architecture in 2017. [2] In June 2018, OpenAI released a paper entitled "Improving Language Understanding by Generative Pre-Training", [ 3 ] in which they introduced that initial model along with the ...
