OpenAI's AI coding assistant, Codex, is now accessible to ChatGPT Plus users, enabling individual developers and smaller teams to leverage its capabilities. Codex has been upgraded with internet access, voice input, and improved software development tools. Internet access facilitates interaction with web-dependent tasks and can be controlled to enhance safety. With voice input, developers can issue verbal instructions, enhancing accessibility. The streamlined handling of pull requests decreases repository clutter, boosting operational efficiency. Users can manually activate internet access, while openAI closely monitors for potential prompt injection attacks.
