OpenAI has launched a new open-source coding tool called Codex CLI, which allows programmers to use artificial intelligence to help with coding tasks directly from their terminal software. This new tool is designed to work with OpenAI's latest AI models, making it easier for developers to access the power of AI when writing code. By running locally on a user's computer, Codex CLI can assist with a variety of coding tasks, bringing AI closer to the programming process. This launch is part of OpenAI's efforts to make AI more accessible and integrated into everyday programming.
