Abstract: A method of improving a language model and outputs of the language model. An output is received from a language model executed on an initial prompt. The output is validated by comparing the output to one or more rules. The output is determined to have failed to validate and in response, an updated prompt is generated. The updated prompt includes the output, at least one rule that caused the output to fail to validate, and an instruction to correct the output based on the at least one rule. The language model is executed on the updated prompt to generate a corrected output, which is validated by comparing the corrected output to the one or more rules. The language model is retrained on training data comprising at least the one or more rules, the output, the updated prompt, and the corrected output to yield a retrained language model.
