A hybrid client and server ranking system downloads and update from the backend system to a temporary storage location on the computing device and validates the update to the model without loading it permanently into the application by executing the update to the model with no data to generate an evaluation score and determining that validation passed or failed based on the evaluation score. Based on determining that validation passed, the hybrid client and server ranking system generates an updated model by updating the model with the update to the model. The hybrid client and server ranking system can further generate composite features comprising new features and local features currently stored on the computing device. The hybrid client and server ranking system generates, using the updated model and the composite features, a ranked list of content. The ranked list of content can be displayed on a computing device.

Methods and systems are disclosed for sharing collections of content items in chat sessions. The methods and systems receive a request to share a first content item and present a GUI comprising a first set of options and a second set of options, the first set of options being associated with adding the first content item to a collection of content items that is accessible to a plurality of recipients, the second set of options being associated with sending the first content item to individual recipients. The methods and systems determine a set of target recipients of the first content item and select a content sharing link between a first link to the collection of content items and a second link directly to the first content item. The methods and systems send, to a target recipient, the content sharing link that has been selected.

Sharing content item collections in a chat

A sender holds a first platform account with an interaction system. The sender selects a content item to be shared with a recipient. In response to determining that a recipient identifier of the recipient is not linked to a platform account, an off-platform communication is transmitted to a second user device associated with the recipient identifier. The off-platform communication is in an electronic format supported by the second user device and contains a user-selectable registration link. In response to detecting establishment of a second platform account linked to the recipient identifier, the recipient is enabled to access the content item on the second user device via a user interface provided by an interaction application. A relationship between the first platform account and the second platform account is established within the interaction system.
