Ercan Ermis created prompt-caching.ai to address the high costs of multi-turn AI interactions. The tool automates the injection of cache_control breakpoints, which is often done manually or inefficiently, leading to significant token waste.
Business Model
Revenue Model
Open Source (MIT License). Free for public use.
Pricing Tiers
The tool is released under the MIT License. Users only pay for the underlying Anthropic API usage (0.1x for cache reads, 1.25x for cache creation).
