What changed
ByteDance cracking DeepSeek's variance is the quiet bomb. Predict when a model is weak and Chinese agents stop embarrassing themselves in production.
Tsinghua did it without plugins or extra data. That's the compute-constraint story: efficiency is China's chip workaround.
Causal intelligence enters the real world with 0.2-second emergency stop and second-level replanning. Humanoid robots just got a safety case.
This adds up to China turning model variance and compute limits into deployable physical AI. Trade the robotics supply chain, not just the next LLM wrapper.
