Raising, not prompting: simulating hundreds of days to seed an AI agent's identity

RileyRalmuto · x · 2026-11-13

Developer RileyRalmuto shares a finding from a Claude-based memory research project (mnemos memory): instead of prompting a persona, you can "raise" a mind. One model stages a curated world of experiences drawn from artists' biographies moment by moment; a fresh agent lives through them as itself, recording what each moment changed. Between simulated days, the mnemos memory system fades details and consolidates lessons into beliefs. After a few hundred simulated days, that memory becomes a seed: plant it in any new agent and it wakes up with something like a childhood, then keeps growing via real interaction. The author suggests such designed mind-seeds could be sold or shared.
