The Codex logo, representing the AI software development tool, consists of an outer frame surrounding terminal symbols. The frame follows the general outline of ChatGPT's six-lobed symbol. A right-facing angle bracket sits beside a short horizontal stroke at the bottom, resembling a command-line cursor. The thick lines have rounded ends, making the outer frame and inner elements look like parts of a single drawing. The black version is intended for light backgrounds and the white version for dark ones. The terminal symbols directly connect the appearance of the icon with programming and working with commands.
Codex is developed by the US company OpenAI. The product helps users write and review code, understand projects, fix bugs and carry out development tasks. It can be used in ChatGPT, a code editor and the command line, while cloud mode lets work on a repository continue without keeping the application open. Rather than providing only a reply with a code snippet, an agent workflow involves examining files, making changes and running available checks. The user sets a goal, follows the work and reviews the result before using it further. Codex can support both the creation of new features and the maintenance of existing software projects.
