Abstract: A method, apparatus, device, and medium for action execution are provided. In a method, a set of actions to be executed at a first device is determined from a plurality of actions based on a first action model at the first device. A data accumulated indicator associated with the set of actions is obtained. In response to that the data accumulated indicator meets a predetermined condition, parameter data associated with the set of actions is transmitted to the second device to cause the second device to update a second action model at the second device using the parameter data. By means of the example implementations of the present disclosure, sufficient consideration is given to rewards and consumption related to executing actions, and each action can be executed under the condition that consumption constraints are met, so as to increase the corresponding reward.
