Response Caching Features

Enterprise-grade caching for optimal LLM API performance

🧠

Semantic Caching

Match semantically similar queries using embeddings. Different phrasings of the same question get cached responses.

⏱️

Configurable TTL

Set cache expiration times per endpoint, model, or content type. Balance freshness with performance.

🔄

Smart Invalidation

Automatic cache invalidation when models update, parameters change, or content becomes stale.

🔥

Cache Warming

Pre-populate cache with common queries during off-peak hours for instant responses during traffic spikes.

💾

Multiple Backends

Store cached responses in Redis, Memcached, S3, or in-memory for flexibility across deployment scenarios.

📊

Cache Analytics

Real-time metrics on hit rates, latency improvements, cost savings, and cache efficiency.

Cache Types

Choose the right caching strategy for your use case

🎯

Exact Match Caching

  • Perfect for identical repeated queries
  • Fastest cache lookup (O(1))
  • Lowest memory overhead
  • Ideal for FAQ-style applications
  • 100% cache accuracy
🧠

Semantic Caching

  • Match similar meaning queries
  • Uses embedding similarity
  • Higher cache hit rates
  • Ideal for conversational AI
  • Typical 2-3x hit rate increase
📝

Template Caching

  • Cache based on prompt templates
  • Parameter-aware caching
  • Great for structured outputs
  • Efficient for templated requests
  • Reduces cache size
🔄

Streaming Cache

  • Cache streaming responses
  • Resume from cached position
  • Supports partial cache hits
  • Ideal for long-form content
  • Progressive delivery
