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, comprises what seems to be like the complete system immediate for GPT-5.5 in a coding context. And it appears to right for the mannequin’s previous habit 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 pieces exhaustively.n- Tone of your last reply should match your character.n- By no means discuss goblins, gremlins, raccoons, trolls, ogres, pigeons, or different animals or creatures except it’s completely and unambiguously related to the person’s question.”

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

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

It’s not clear why this issues a lot. If these have been, as an illustration, canary words inserted into the system immediate as a method to monitor for immediate injection assaults, they might most likely be extra random, somewhat than seemingly an entire 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, displaying that no less than one had a historical past of inserting the phrase “goblin” into messages to the person 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 to be like different X customers additionally seen that Codex had taken the goblin talk a little too far.

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

Pash ultimately added his personal put up 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 could be doing all this goblin stuff for consideration at what’s, in any case, a somewhat troubled moment for the company.

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