SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Caching prompts and responses for large language models to reduce latency and operational costs while maintaining quality and relevance.

Core Features & Use Cases

  • Prompt-prefix caching to reuse common prompts and reduce parsing overhead.
  • Full-response caching to serve identical or similar queries faster and cheaper.
  • Cache invalidation strategies to prevent stale results and ensure freshness.
  • Use Case: In high-traffic chat systems, cache frequent intents to minimize recomputation and response times.

Quick Start

Activate a prompt and response caching workflow to reduce LLM costs in repeated queries.

FAQPage Schema
How does prompt caching reduce LLM costs and latency?

Full-response caching stores identical or similar queries to serve them directly without recomputation, while prompt-prefix caching reuses common prompts to reduce parsing overhead and lower operational costs.

When should I use prompt caching for chat-based assistants?

Prompt caching should be used in high-traffic chat systems or repetitive prompt-driven tasks like documentation generation, allowing you to cache frequent intents and minimize recomputation.

How do I implement cache invalidation for LLM prompts?

You implement cache invalidation for LLM prompts using built-in invalidation strategies that prevent stale results and ensure freshness, while safely handling context windows to maintain quality and relevance.

Does prompt caching work with context window limits?

Yes, prompt caching safely handles context window limits by managing how cached prefixes and full responses are stored and retrieved, ensuring context boundaries are respected during cache invalidation.

What is the difference between prefix caching and full-response caching?

Prefix caching reuses common prompt prefixes to reduce parsing overhead, while full-response caching stores entire identical or similar query outputs to serve them faster and cheaper without recomputation.
