Let me be brutally honest: every large language model you've ever used — GPT-5.5, Claude, Gemini, Llama — they all suffer from the same fatal flaw. They're geniuses at everything and masters of nothing. They can write Python. They can explain quantum physics. They can draft a legal contract. And every single time, they get the gist right but the details wrong. The code has subtle bugs. The physics is hand-wavy. The contract misses a clause that would cost you millions. What if I told you I designed an architecture that fixes this — permanently — by splitting AI into 200+ hyper-specialized expert models , each one a world-class authority in exactly ONE tiny niche, all orchestrated by a single routing brain? This is Tianshu (天枢) — the Ultra-Fine-Grained Mixture-of-Experts architecture — and I'm going to break down every layer of it. Buckle up. This is long. This is dense. This is the most detailed MoE architecture you'll ever read on the internet.…
