OpenAI launches Codex, a new AI coding agent for software development

Bottom line: Codex aims to streamline routine programming work and set a new standard for AI-driven software engineering. As the technology matures, OpenAI envisions Codex and similar agents playing an increasingly central role in the future of software development. OpenAI has introduced Codex, a new AI-powered coding agent now available as a research preview to select ChatGPT subscribers. This launch marks a significant milestone for the company, signaling its ambition to redefine how software engineers interact with artificial intelligence in their daily workflows. Codex is built on a specialized version of OpenAI's o3 reasoning model, known as codex-1, which has been fine-tuned specifically for software engineering. This model was trained using reinforcement learning on various coding tasks, enabling it to generate cleaner, more reliable code that closely follows user instructions. Unlike earlier models, codex-1 iteratively tests its output, ensuring its code passes necessary che ... Read full article.
