Cache mismanagement is silently burning agent budgets: how to fix it
brandon_galang · x · 2026-10-12
An experienced agentic engineer warns that mishandling prompt caches silently burns budgets: most APIs have 5-minute cache TTLs, so gaps between prompts—or juggling parallel sessions—mean paying full input-token price every message. His fixes: switch to providers with 1-hour TTL (e.g. Anthropic), limit parallel sessions, and compact large resumed sessions with a smaller model (he uses 5.6 luna high in Cursor).
