# Customization in AI Infrastructure

**Customization** is the first pillar of the [[concept-3c-framework|3C Framework]]. Chinese AI solution providers eschew the pursuit of purely general-purpose solutions in favor of building **modular, adaptable infrastructure** tuned to local technical, regulatory, and operational needs. This takes the form of easy-to-install, subscription-based AI services engineered for specific local contexts — especially in nuanced sectors like finance and healthcare.

A prime example is **[[entity-ant-group-d2|Ant Group]]'s AI doctor agents** on the Alipay app. These agents are trained not just on general data, but specifically on **clinical literature, structured diagnostic data, and the actual decision-making logic of top Chinese physicians**. That contextual depth is the point: customization means encoding domain expertise into the infrastructure layer, not just prompting a general model.

Infrastructure customization also happens below the model. **[[entity-alibaba-d2|Alibaba Cloud]]** offers storage optimized specifically for generative-AI read/write speeds — a hardware-level tuning that general-purpose clouds don't necessarily prioritize. This operational agility is difficult for decentralized, general-purpose ecosystems to match because customization here depends on owning and tuning the full stack — see [[concept-vertically-integrated-ai]].
