OpenAI Codex is an artificial intelligence model developed by OpenAI. It parses natural language and generates code in response. It powers GitHub Copilot, a programming autocompletion tool for select IDEs, like Visual Studio Code and Neovim. [1] Codex is a descendant of OpenAI's GPT-3 model, fine-tuned for use in programming applications.
GitHub Copilot was initially powered by the OpenAI Codex, [13] which is a modified, production version of the Generative Pre-trained Transformer 3 (GPT-3), a language model using deep-learning to produce human-like text. [14]
The loss incurred on this batch is the multi-class N-pair loss, [12] which is a symmetric cross-entropy loss over similarity scores: / / / / In essence, this loss function encourages the dot product between matching image and text vectors to be high, while discouraging high dot products between non-matching pairs.
OpenAI cited competitiveness and safety concerns to justify this strategic turn. OpenAI's former chief scientist Ilya Sutskever argued in 2023 that open-sourcing increasingly capable models was increasingly risky, and that the safety reasons for not open-sourcing the most potent AI models would become "obvious" in a few years.

The AI-powered chatbot will include web links in responses for the first time, as it looks to take on Google.
OpenAI o1 is a 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 ]
OpenAI said it collaborated extensively with the news industry and gathered feedback from its partners on the search function. Any website or publisher can choose to appear in ChatGPT search.
