ClaimWriter cuts deep research hallucination up to 4.5×

Faithfulness can be fixed at the drafting stage rather than by better retrieval — the writer, not the search, is where most hallucinations enter. Teams building deep research pipelines can plug ClaimWriter into existing frameworks and audit outputs with ClaimProbe using the released code. The benchmark offers a reproducible baseline for measuring claim-level grounding across competing agent stacks.

Harvey LAB-AA v1.1 Adds Hallucination Gate to Legal Benchmark

The hallucination gate reshuffles the leaderboard: Muse Spark 1.3 would lead at 26.7% all-pass without it, but two thirds of its passes contain material hallucinations, while GPT-6 Astra keeps nearly all its passes and jumps from joint 10th to 3rd. Legal tech teams benchmarking models for drafting work should weight groundedness over raw pass rates, and cost data matters too — Grok 4.7 tops the table at roughly US$9.50 per task, under half the ~US$21.70 of Claude Fable 5.1.
