Why architecture matters here

CoVe adds cost but reduces hallucination when accuracy matters. Architecture matters because isolation + claims + revise compose.

The architecture: every piece explained

The top strip is loop. Draft answer. Plan verifications. Answer each. Compare to draft.

The middle row is output. Revise draft. Final answer. Isolation is key. Batched calls.

The lower rows are ops. Cost. Metrics. Ops — when to apply + when not + budget.

End-to-end flow

End-to-end: user question. LLM drafts answer. Extract 5 claims. For each, ask verification Q in isolated call. Contradictions flag claims. Revise draft to drop or correct. Return final.
