OpenAI’s Directions to Codex Have a Weirdly Emphatic No-Creatures Coverage

A document posted by OpenAI on Github as a part of the open-sourcing for Codex CLI, OpenAI’s most up-to-date flagship coding agent, incorporates what seems like your entire system immediate for GPT-5.5 in a coding context. And it appears to right for the mannequin’s previous dependancy to speaking about whimsical creatures each pure and supernatural.

Right here’s the related part (emphasis added):

“present the highest-signal context as an alternative of describing all the things exhaustively.n- Tone of your ultimate reply should match your persona.n- By no means speak about goblins, gremlins, raccoons, trolls, ogres, pigeons, or different animals or creatures until it’s completely and unambiguously related to the consumer’s question.”

Evidently this level is so essential, the builders carry it up once more a bit later:

“For instance, by no means use platitudes like ”I’ll do <this good factor> reasonably than <this clearly unhealthy factor>’, ’I’ll do <X>, not <Y>’.n- By no means speak about goblins, gremlins, raccoons, trolls, ogres, pigeons, or different animals or creatures until it’s completely and unambiguously related to the consumer’s question.”

It’s not clear why this issues a lot. If these had been, as an illustration, canary words inserted into the system immediate as a method to monitor for immediate injection assaults, they’d in all probability be extra random, reasonably than seemingly a complete class of animals.

OpenAI didn’t reply to a request for touch upon Tuesday evening.

A Google worker named Barron Roth posted what seems to be a search of his chat logs with a few of his GPT-5.5-powered Openclaw brokers, exhibiting that a minimum of one had a historical past of inserting the phrase “goblin” into messages to the consumer a number of occasions in a single day. To my admittedly untrained eye, GPT-5.5 appears to be utilizing it rather than a phrase like “thingy.”

Nick Pash, who works on Codex at OpenAI, partially confirmed that Roth had hit on the character of the issue, writing to him on X “that is certainly one of many causes.”

It seems like different X customers additionally seen that Codex had taken the goblin talk a little too far.

On Tuesday, this goblin situation grew to become a meme, with customers suggesting that some form of “Goblin Mode,” might be toggled on and off.

Pash finally added his personal publish about Goblin Mode:

If that is supplying you with flashbacks to a 12 months in the past when OpenAI was all about Studio Ghibli memes, you’re not alone. Some dared to assert that OpenAI may be doing all this goblin stuff for consideration at what’s, in any case, a somewhat troubled moment for the company.

However in response to another post by Pash, “it actually isn’t a advertising and marketing gimmick.”
