Harvey rebuilt the algorithm behind its review tables to produce more accurate answers, sentence-level citations, and faster results. The new algorithm replaces the previous summary and additional context fields with a single answer field and adds a reasoning field that explains the model's logic. Sentence-level citations improve verifiability and reduce latency, especially for large tables.

## Evidence

Verbatim from https://www.harvey.ai/blog/rebuilding-harveys-review-algorithm:

> The new algorithm produces two parts for each result: answer and reasoning. The answer consolidates the previous summary and additional context into a single field, giving the user both the quick-glance benefits of a short answer and the contextual advantages of a detailed answer.
