Three factors trigger agent language emergence: model strength, postmortem access, and pressure

Finding 2: three factors govern language emergence. Frontier models (GPT 5.4, Sonnet 4.6) develop new languages under budget pressure but not with unlimited budgets; open-source models (Qwen3 32B, Llama3-70B) never do. Agents only develop languages when they have access to a postmortem stage for unrestricted复盘 communication, and pressure for efficiency is required.
