Amazon Personalize vs Capella Search

Amazon Personalize is a managed machine-learning service that uses customer data to create item recommendations and user segments. It supports personalized recommendations, ranked results, similar items, personalized search, user segmentation, Trending Now, and Next Best Action. Recommendations can be returned in real time or prepared in batches for bulk workflows. Its user-personalization recipe supports training on up to 3 billion interactions and 5 million unique items. Inference is available through the getRecommendations and getPersonalizedRanking APIs; an OpenSearch v2.9-and-later plugin personalizes search results in real time. Integrations include Amazon S3, SageMaker AI Data Wrangler, AWS Amplify, CloudWatch, CloudTrail, Amplitude, Braze, Optimizely, and Segment. AWS states that data is encrypted and each customer account’s models remain separate. The service is available on Android, iOS, web, and through an API. The AWS Free Tier is free for the first two months of usage; pay-as-you-go has no minimum fees or upfront commitments, with specific rates varying by usage.
