Details

  • Codex now features internet connectivity, enhancing its coding capabilities, but this option remains off by default to prioritize user security.
  • OpenAI has expanded Codex access to ChatGPT Plus subscribers, no longer limiting it to Enterprise and Team tiers.
  • Users must explicitly turn on web access after reviewing updated risk information detailing potential vulnerabilities and tradeoffs.
  • With internet access, Codex can perform real-time API integrations and manage dependencies while coding.
  • The system runs in a sandboxed cloud environment, offers integration with GitHub repositories, and leverages AGENTS.md guidance files for contextual code understanding.

Impact

This move intensifies competition with Anthropic's Claude Code and Google's Gemini Code Assist, both of which recently upgraded their coding assistants. By opening Codex's capabilities to the ChatGPT Plus tier, OpenAI broadens access to more developers and independent users. However, enabling web connectivity brings new benefits and also demands fresh scrutiny of security and responsible AI use.
