  • Publication number: 20250265629
    Abstract: An online concierge system generates a plurality of bundles based in part on a seed list of contexts by generating one or more prompts that are provided to a machine learned model, where for a first context of the seed list of contexts, a prompt instructs the machine learned model to determine: a first bundle for the given context, where the first bundle includes a list of products, a title, and an explanation. The plurality of bundles is stored in a datastore. The system selects, for a customer, the first bundle from the plurality of bundles in the datastore, and generates a list of items from an online catalog that corresponds to the list of products of the first bundle. The system provides the list of items, the title, and the explanation for presentation to a customer client device of the customer.

  • Patent number: 12337160
    Abstract: A medicament delivery device has an actuation member which is movable relative to a body. The actuation member has a flexible arm comprising an engagement surface. The device has a contoured surface. When the actuation member is in a first position the engagement surface engages the contoured surface. When the actuation member moves to a second position, the flexible arm is deflected radially by the engagement of the engagement surface with the contoured surface. The device further has a blocking member. The blocking member has a proximal portion which engages the flexible arm when the blocking member is in an extended position for preventing the flexible arm from being deflected radially and moving distally. The blocking member is movable relative to the body to disengage the proximal portion from the flexible arm.
