No image will be stored. Only the extracted face features are stored on server until [LargeFaceList - Delete](https://docs.microsoft.com/rest/api/faceapi/largefacelist/delete) is called.<br> Find Similar is used for scenario like finding celebrity-like faces, similar face filtering, or as a light way face identification. But if the actual use is to identify person, please use [PersonGroup](https://docs.microsoft.com/rest/api/faceapi/persongroup) / [LargePersonGroup](https://docs.microsoft.com/rest/api/faceapi/largepersongroup) and [Face - Identify](https://docs.microsoft.com/rest/api/faceapi/face/identify).<br>''recognitionModel'' should be specified to associate with this large face list. The default value for ''recognitionModel'' is ''recognition_01'', if the latest model needed, please explicitly specify the model you need in this parameter. New faces that are added to an existing large face list will use the recognition model that''s already associated with the collection. Existing face features in a large face list can''t be updated to features extracted by another version of recognition model. Please refer to [Specify a recognition model](https://docs.microsoft.com/azure/cognitive-services/face/face-api-how-to-topics/specify-recognition-model).<br><br>Large face list quota:<br>* Free-tier subscription quota: 64 large face lists.<br>* S0-tier subscription quota: 1,000,000 large face lists.'
