Prompt Caching Patterns

Implement effective caching strategies to reduce LLM costs by up to 90%.

When to Use

• Same or similar prompts are sent repeatedly
• Large system prompts are reused across requests
• Responses can be reused for identical queries
• Need to reduce latency for common requests
• Optimizing costs for high-volume applications
