Mulling
/ˈmʌl.ɪŋ/ (warm, spiced; best served in cold weather)v. intr.Common
Etymology
From Mid. Eng. mull (to heat and spice a beverage) + deliberative latency jargon, 2022; the thermal metaphor is considered accurate by the thermal engineering team, though for unrelated reasons
Definition
A controlled, low-temperature cognitive process in which Claude warms a partially-formed idea by rotating it slowly through successive attention layers, adding spice tokens where appropriate, until the response achieves optimal conceptual temperature. Not to be confused with Marinating, which involves immersion rather than heat.

Usage
