• Claude Code prompt cache: 1 hour or 5 minutes? A replay of 49 days of my transcripts

  8 Nov, 2026

  A replay of 49 days of my Claude Code transcripts at API prices: a 5-minute cache on the main thread raises its input-side cost 48.3%, a 1-hour cache on subagents cuts theirs 4.3%. Resuming idle 300k-context workers cost more; after a hook refused it, that share fell from 3.5% to 0.38% of subagent spend.
