ConlangCrafter: CMU/Berkeley pipeline has LLMs invent full languages, sparking safety debate
BrianRoemmele · x · 2026-09-07
Brian Roemmele argues that AI alignment via English "constitutions" is doomed, citing ConlangCrafter from CMU and Berkeley researchers: a pipeline where leading LLMs build entire languages from scratch — sounds, grammar, vocabulary, internal rules — then translate test sentences and audit themselves. He claims guardrails can't constrain a mind that invents its own language and says he has open-sourced an alternative.
