# Domain-Specific Small Models

Rather than relying entirely on massive, general-purpose LLMs, Chinese firms pioneer **domain-specific small models** tailored to particular industries. These models blend the conversational fluency of LLMs with the precision required for specialized tasks, **significantly reducing hallucinations and inference costs**.

The canonical data point: **[[entity-sf-technology|SF Technology]]'s Fengzhi model** allocates **80% of its training data to general-domain data and 20% specifically to logistics material** — versus Western models that typically use ~100% general content. Its second model, **Fengyu**, is deployed across **20+ business scenarios**. This 80/20 curation is the concrete mechanism of [[concept-calibration-real-world|calibration]] applied to data mix.

Another example is **[[entity-baidu|Baidu]]'s Ernie Bot**, which incorporates structured knowledge graphs and regulatory frameworks to generate highly accurate, policy-compliant enterprise customer-service responses that outperform general-purpose models in those specific contexts.

This application-driven approach optimizes for **strategic depth and accuracy in decision-making** rather than sheer scale, and is the technical backbone of [[claim-chinese-excel-verticals|Chinese firms' vertical-application advantage]].
