Clarifai Release 6.5 introduces significant enhancements to its search capabilities and user authentication processes, including the implementation of Social Single Sign-On (SSO). The update to search functionalities features a complete overhaul of the search APIs, enabling users to search for images by concept, visual similarity, or metadata, with automatic indexing upon upload. The release introduces a more versatile visual search that operates without the necessity of pre-labeling or training models with specific concepts, allowing localized search through detected image regions. Video search is also enhanced, treating each video frame as an individual image for search purposes. Additionally, the integration of Social SSO simplifies user access by allowing logins through existing Google and GitHub accounts, eliminating the need for new sign-up processes or passwords.
