Blanching

Etymology

from O.Fr. blanchir (to whiten) + the culinary preprocessing tradition of brief thermal exposure to halt enzymatic activity; adopted by spinner engineers who needed a word for 'brief alarming pause before proceeding normally'

Definition

A brief, high-temperature preprocessing pass in which Claude rapidly neutralizes the most volatile elements of a user's prompt before the main reasoning cycle begins. As in culinary Blanching, the process is fast, slightly traumatic for the subject matter, and produces a more stable final product.
