The difference between OpenConfig and native YANG data models lies in their development and purpose:

D: Native models are developed by vendors and are specific to their platforms. They are designed to integrate features or configurations that are relevant only to that vendor’s platform. Native models, being vendor-specific, provide the most detailed and granular control over the vendor’s devices1.

OpenConfig models, on the other hand, are developed by a collaborative group of network operators and are intended to be vendor-neutral. They aim to provide a more standardized model that can be used across different vendors’ equipment, focusing on the needs of the operators rather than the specific capabilities of the devices1.
