Couchbase Capella has introduced a Private Preview of its AI services, focusing on the Model Service, which facilitates the deployment of private language and embedding models securely at scale. This service is designed to overcome regulatory challenges faced by enterprises, such as GDPR and PII protection, by allowing AI models to function within an organization's internal network, ensuring data security and compliance. The Model Service offers features like secure model deployment, OpenAI-compatible APIs, and performance enhancements such as caching and batching, along with tools for content moderation and keyword filtering. Users can deploy models to improve performance while keeping data within the operational cluster's network, addressing latency and compliance issues. The blog also provides a tutorial on deploying and using models in Capella, highlighting its value-added features to enhance AI application performance. The service is available for Private Preview, encouraging users to provide feedback for future development.
