Model selection method and terminal

A terminal, comprising a memory and a processor, wherein

• the memory is configured to store one or more computer programs, and when the one or more computer programs stored in the memory are executed by the processor, the terminal is enabled to implement the following steps:
• obtaining first behavior data generated when a user operates the terminal;
• selecting, according to a preset policy, a first model from a plurality of models stored on the terminal;
• running the first model by using the first behavior data as an input parameter of the first model, to obtain a first output result;
• providing a first artificial intelligence (AI) service based on the first output result;
• selecting a second model from the plurality of models when the first model does not meet a condition;
• running the second model by using second behavior data as an input parameter of the second model, to obtain a second output result, wherein the second behavior data is generated after the first behavior data, and is generated when the user operates the terminal;
• and
• continuing to provide the first AI service based on the second output result.
