GlossoGen study shows AI agents evolve and transmit new languages

EliasEskin · x · 2026-09-03

A study with Schmidt Sciences and AE Systems rigorously examines LLM agent language emergence, beyond anecdotal single-run evidence. Key findings: emergence depends on model strength, scratchpad message access, and efficiency pressure; the emergent languages are morphologically productive and compositional; and they can be culturally transmitted to new agents, even weaker models that couldn't develop language themselves. The team built GlossoGen, a platform for controlled, sandboxed multi-agent experiments with configurable initial conditions.
