How to Make Your AI App Feel Magical: Prompt Caching

Prompt caching is a technique used by AI apps to improve speed and user experience. It involves pre-loading relevant information as soon as users start interacting with the app, reducing response times. OpenAI and Anthropic are two major providers offering unique prompt caching solutions. OpenAI's approach automatically stores prompts, tools, and images for a smoother experience, while Anthropic's caching provides more granular control, allowing developers to specify what to cache. Both systems have their strengths: OpenAI is optimal for shorter prompts with frequent requests, offering a 50% cost reduction on cache hits; Anthropic excels with longer prompts and provides more control over cached elements, ideal for apps requiring selective storage. Properly structuring prompts for caching can significantly enhance speed, making AI apps feel magical to users.
