- Who is affected: Developers and users of OpenAI's Codex, particularly those using GPT-5.5, are directly impacted by these restrictions.
Codex's New Restrictions
OpenAI has placed a ban on its AI Agent, Codex, from referencing goblins and other mythical creatures.
Codex is OpenAI's answer to Anthropic's Claude Code AI Agent.

The newest version has strict behavioural rules.
According to newly released base instructions for GPT-5.5 in OpenAI's Codex CLI, the model is explicitly told to "never talk about goblins.
What to Watch Next
The industry will be watching to see how these restrictions impact Codex's functionality and user adoption. Future iterations of AI models may continue to implement similar behavioral guidelines as AI companies attempt to control outputs.
