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]
In tests users have conducted in the hours since o1-preview became widely available the model does seem able to correctly answer many questions that befuddled previous models, including OpenAI’s ...
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. [3]

OpenAI's new o3 and o3 mini models, which are in internal safety testing currently, will be more powerful than its previously launched o1 models, the company said. ... Microsoft-backed OpenAI ...
Many OpenAI staff thought that o1 was not ready to be unveiled, but Altman pushed to launch it anyway to burnish OpenAI’s reputation as a leader in AI. This is the first time details of this ...
Generative pretraining (GP) was a long-established concept in machine learning applications. [16] [17] It was originally used as a form of semi-supervised learning, as the model is trained first on an unlabelled dataset (pretraining step) by learning to generate datapoints in the dataset, and then it is trained to classify a labelled dataset.
DeepSeek, the Chinese AI startup, shocked the world after unveiling an AI model last week that rivals leading models like OpenAI’s o1, while claiming it cost far less to develop and required far ...
