COMPUTER IMPLEMENTED METHOD FOR OBTAINING AN OUTPUT RESPONSE TO A NATURAL LANGUAGE INPUT PROMPT

Computer implemented method for obtaining an output response to a natural language input prompt, the output response being generated by a language model selected from a group of language models, comprising the steps: - receiving the input prompt; 10 - determining a complexity score of the input prompt; - determining a time-criticality score of the input prompt; - for each language model, computing a quality of service score related to the combination of the language model 15 and the input prompt, on the basis of the complexity score of the input prompt, the time-criticality score of the input prompt, a stored response quality function of the language model and a stored latency function of the language model; 20 - selecting a selected language model on the basis of the computed quality service; - forwarding the input prompt to the selected language model; - receiving the output response generated by the selected 25 language model on the basis of the input prompt.
