System

A system comprising:

• circuitry configured to:
• receive, via a communication interface coupled to a packet-switched network, attribute data records each including age, physiological condition indicators, allergen flags, and dietary preference parameters for each member of a family;
• compute per-user nutritional requirement values by applying a constraint optimization to the attribute data records and reference nutritional data stored in a memory;
• generate, by inputting the per-user nutritional requirement values into a large language model as a structured prompt character string, a nutritionally balanced meal plan satisfying the per-user nutritional requirement values;
• validate the meal plan by comparing each entry against allergen exclusion rules derived from the allergen flags, and upon detecting a violation, regenerate the meal plan by inputting a revised prompt character string into the large language model;
• derive from the validated meal plan an aggregated ingredient list with quantities and transmit the aggregated ingredient list to an external ordering service over the packet-switched network;
• generate, by inputting the meal plan and apparatus capability parameters into the large language model, procedure data indicating a sequence of cooking steps with temperature, duration, and stirring parameters;
• and
• transmit, via the communication interface, control command data derived from the procedure data to a cooking apparatus over the packet-switched network to cause the cooking apparatus to execute the sequence of cooking steps.

A method performed by circuitry of a system, the method comprising:

• receiving, via a communication interface coupled to a packet-switched network, attribute data records associated with a plurality of user profiles, each attribute data record including a plurality of user-specific parameters;
• computing, based on the attribute data records and reference data stored in a memory, per-user requirement values for each of the plurality of user profiles;
• generating, by inputting the per-user requirement values into a data generation model, a composite output plan satisfying constraint conditions derived from the per-user requirement values;
• generating, based on the composite output plan, instruction data including a sequence of operational parameters;
• and
• transmitting, via the communication interface, the instruction data to a controlled apparatus over the packet-switched network to cause the controlled apparatus to execute operations in accordance with the operational parameters.
