The claim-verification cost profile, stage by stage
Per-claim verification is the defense against citation hallucination. It also costs real money. A breakdown of token costs at each stage of the verification pipeline, with the numbers we actually see in production.
Numeric claim extraction and verification
How we parse numbers from drafts — percentages, dollar figures, head counts, dates — and check each one against a KB source before the sentence ships. The pipeline, the regex floor, the LLM ceiling, and what we still get wrong.
The hallucination budget, per claim
Treat hallucination as a cost: each claim in a draft has a probability of being mis-attributed. Here's how we budget it, how we trade latency against grounding strength, and why the budget is per-claim, not per-draft.
The claim-level verification pass, explained
After the draft model writes a sentence, a smaller verifier model reads each substantive claim and asks: is this entailed by the source block? Here's how that works, what it costs, and where it still misses.
Grounded Retrieval 101, Part 2: why citations don't guarantee groundedness
A citation tells you which passage was retrieved. It does not tell you whether the cited passage actually supports the generated claim. Part 2 of the Grounded Retrieval series — the entailment gap, and what closes it.
