A developer proposes a method to combat confabulations in Large Language Models (LLMs) by enforcing that every factual claim made by the model must be an exact quote from the source document. This approach, termed "proof-based grounding," involves classifying output fields as either copied or composed and using code to verify that all factual fields are direct copies. The prompt should explicitly state the rule that will reject answers not found by exact string matching, and constraints like maximum item counts or string lengths should be enforced in the schema rather than prose to prevent the model from deviating.
