Covers pricing models, TTLs, and key differences: Anthropic offers explicit cache_control breakpoints with 90% read discounts but 5-minute TTLs; OpenAI provides automatic caching with 50% discounts and no configuration; Gemini supports long TTLs up to 24 hours with per-hour storage billing. Includes real cost numbers from a 50k requests/day support bot showing 85% cost reduction, common hit-rate failure patterns (multi-tenancy, TTL mismatches, silent invalidation from prompt changes), and structural rules for designing cacheable prompts. Recommends choosing caching strategy per feature rather than per provider. ## Full article daily.dev links to this article rather than hosting it.
