Claude Code Auto Dream: Automatic Memory Consolidation During Idle Periods — Based on Sleep-Time Compute Research (5× Compute Reduction at Equal Accuracy)

SFEIR Institute·medium signal

Claude Code is rolling out Auto Dream, a background sub-agent that consolidates memory files every 24 hours after 5+ sessions. It deduplicates entries, converts relative dates to absolute, removes contradicted facts, and keeps MEMORY.md under 200 lines — all during idle periods when the developer isn't actively working. Built on Letta/UC Berkeley's sleep-time compute research showing that pre-computing during idle time reduces test-time compute by 5× at equal accuracy, with up to 18% accuracy gains.
