CDEDUP: collapsing the answers that mean the same thing
A semantic cache slowly accumulates near-duplicate answers. CDEDUP finds the clusters that mean the same thing and collapses them, reclaiming memory, and Crowkis is honest about its cost.

Boring on purpose: the operational philosophy
Exciting infrastructure is a contradiction in terms. Every Crowkis design decision optimizes for the same review: 'it just runs.'

securityMay 10, 2026· 3m
Closed-source as a security posture, argued honestly
