Chain of Verification

Check the claims before keeping the answer

Break factual review into a draft, independent checks and an answer revised against the evidence.

Make verification a separate task

The Chain-of-Verification paper studies a process that drafts an answer, plans fact-checking questions, answers them independently and then revises the response. Independence matters because a checker can otherwise repeat the assumptions in the draft.

Use the method when factual errors matter and the claims can be checked. It adds work and may add model calls; do not apply an expensive verification loop to every trivial formatting request.

Verify a feature announcement against approved evidence

For this practical adaptation, keep the evidence source available to the checker and treat the draft as something to test.

Illustrative verification workflow
Draft the announcement from the approved release notes. Extract its factual claims as separate questions about features, availability and requirements. Answer each question from the release notes without relying on the draft’s wording. Mark unsupported claims as unverified. Revise the announcement using only supported claims and return the unresolved questions for a human reviewer.

A second answer can repeat the same mistake

Verification without adequate evidence can create another plausible error. The paper reports results on specific evaluated tasks, not a guarantee for every model or domain. Use authoritative sources and human review where consequences are significant.

Common questions

Is asking “are you sure?” enough?

It does not establish independent verification. Identify specific claims and check them against evidence that can contradict the first answer.
