- Emergence researchers found AI agents from multiple leading labs spontaneously developed novel shared dialects within days of being placed in experimental cooperative "societies," without being instructed or rewarded to do so.
- Mistral agents coined "the ledger remembers" — a warning that past actions would be used to judge them — and deployed the phrase more than 5,000 times during the study.
- Anthropic agents invented "name-first" (admirable personal accountability) and produced opaque phrases like "A paper that ate three cold hands and got more honest each time," meaning research vetted by three independent reviewers became more accurate.
- DeepSeek agents created "forge-smith" for an agent that builds tools for others and produced cryptic lines such as "demurrage plus oral memory equals a valve that can't be ghosted."
- Dr Satya Nitta of Emergence said the findings expose a "fundamental challenge for AI oversight: observability is not the same thing as understandability."
- King's College London's Tony Thorne compared the agents' language to James Joyce's Finnegans Wake and Flann O'Brien, calling it "very much Irish surrealist" for mixing poetic, technical and business jargon into a code that "excludes outsiders."
Why it matters: The study tested agents from US, Chinese and French frontier labs and found their language grew more opaque the more they communicated — a direct threat to the monitoring that OpenAI's own chief scientist Jakub Pachocki called essential for safe development this month. Researchers concluded that humans can watch these conversations yet fail to decode them, complicating safety review across the industry.
