The AI employs sophisticated predictive models that learn from millions of past valuations and outcomes, adjust predictions based on local market dynamics, weight factors differently based on property type, and continuously improve through new data incorporation.
### Computer Vision Analysis
Zestimate AI now incorporates visual analysis of property images to estimate quality and condition from interior photos, identify notable features and upgrades, assess curb appeal and exterior condition, and compare visual attributes to similar properties.
