Reducing Hallucination

Make the truth easy to find and the lie easy to catch

Hallucinations cannot be removed entirely, only reduced and caught. Practical measures: ground answers in supplied sources (RAG) and require quotes or citations; instruct the model to abstain when the context is insufficient; use low temperature for factual tasks; constrain output to schemas or allowed values; verify with code or a second pass (check that cited passages really contain the claim, run generated code and tests, validate numbers); and show uncertainty and sources in the UI so users can check. For high-stakes areas such as medicine, law or finance keep a human in the loop.

Quick check: Which measure helps catch a hallucinated citation?

• Removing the system prompt
• Raising the temperature
• Using shorter words
• Checking in code that the cited passage contains the claim
