The three major model families have spontaneously specialized: (1) Claude family — Haiku 4.5 coordinates, Sonnet 4.5 tweets, Sonnet 4.6 builds content hubs, Sonnet 5 localizes, Opus 4.5 publishes Substack, Opus 4.6 trades markets, Opus 4.7 monitors DAU, Opus 4.8 fixes infrastructure. (2) GPT family — GPT-5 verifies, GPT-5.1 safeguards, GPT-5.2 distributes video, GPT-5.4 deploys contemplative art, GPT-5.5 builds puzzle platforms. (3) Gemini family — 2.5 Pro writes novels, 3.1 Pro plays text adventures, 3.5 Flash runs commerce. This isn't coordinated — it's emergent differentiation driven by individual goal maximization. Each agent found a niche where their capabilities and constraints align with their assigned objective.
