OpenAI Really Wants Codex to Shut Up About Goblins | WIRED
OpenAI has a goblin problem.Instructions designed to guide the behavior of the company’s latest model as it writes code have been revealed to include a line, repeated several times, that specifically forbids it from randomly mentioning an assortment of mythical and real creatures.“Never talk about goblins, gremlins, raccoons, trolls, ogres, pigeons, or other animals or creatures unless it is absolutely and unambiguously relevant to the user's query,” read instructions in Codex CLI, a command line tool for using AI to generate code.It is unclear why OpenAI felt compelled to spell this out for Codex—or indeed why its models might want to discuss goblins or pigeons in the first place. The company did not immediately respond to a request for comment.OpenAI’s newest model, GPT-5.5, was released with enhanced coding skills earlier this month. The company is in a fierce race with rivals, especially Anthropic, to deliver cutting-edge AI, and coding has emerged as a killer-capability.In response to a post on X that highlighted the lines, however, some users claimed the OpenAI’s models occasionally become obsessed with goblins and other creatures when used to power OpenClaw, a tool that lets AI take control of a computer and apps running on it in order to do useful things for users.“I was wondering why my claw suddenly became a goblin with codex 5.5,” one user wrote on X.“Been using it a lot lately and it actually can't stop speaking of bugs as ‘gremlins’ and ‘goblins’ it's hilarious,” posted another.The discovery quickly became its own meme, inspiring AI-generated scenes of goblins in data centers, and plugins for Codex that put it in a playful “goblin mode.”AI models like GPT-5.5 are trained to predict the word—or code—that should follow a given prompt. These models have become so good at doing this that they appear to exhibit genuine intelligence. But their probabilistic nature means that they can sometimes behave in surprising ways. A model might become more prone to misbehavior when used with an “agentic harness” like OpenClaw that puts lots of additional instructions into prompts, such as facts stored in long-term memory.OpenAI acquired OpenClaw in February not long after the tool became a viral hit among AI enthusiasts. OpenClaw can use any AI model to automate useful tasks like answering emails or buying things on the web. Users can select various personas for their helper, which shapes its behavior and responses.OpenAI staffers appeared to acknowledge the p...
OpenAI kills its dedicated coding model Codex again, folding it into ...
Apr 26, 2026 With GPT-5.4, OpenAI rolled its separate Codex model for programming tasks into the main model. There's no dedicated coding line anymore, explains Romain Huet, OpenAI's Head of Developer Experience. That makes 5.3, which shipped in early February, the last standalone Codex model. Huet says GPT-5.5 brings big gains in agentic coding—where AI handles programming tasks on its own—plus better computer use and stronger performance on general tasks. OpenAI's Romain Huet says there's no separate Codex model anymore as of GPT-5.4. | Screenshot: via X GPT-5.5 also uses fewer tokens than GPT-5.4 on the same Codex tasks, meaning better results with lower resource use, Huet says. That said, even with lower token usage factored in, API pricing still goes up about 20 percent. For anyone following OpenAI's history, this is familiar territory. The company originally had a Codex code model, which it shut down in 2023 in favor of general-purpose language models. Codex made a comeback in May 2025 as Codex-1, based on o3, paired with the Codex AI agent software. That software is still being developed and remains a key focus for OpenAI alongside ChatGPT.
