OpenAI has unveiled Codex CLI, an open-source coding tool designed to operate directly from terminal software. This new coding agent connects OpenAI’s AI models with local code and computing tasks, enabling users to write, edit, and manage code seamlessly. While it marks progress towards OpenAI's vision for 'agentic software engineers,' Codex CLI focuses on integrating models with command-line interfaces. The company also announced a $1 million initiative to support software development projects utilizing this tool. OpenAI cautions users about the risks of AI in coding, especially concerning security vulnerabilities.
