What is prompt caching in LLMs?
Prompt caching is a technique where the initial part of a long prompt given to a large language model (LLM) is stored in memory after being processed once. This avoids re-computation for subsequent, similar requests, significantly speeding up responses and reducing costs for repetitive queries in financial analysis.
WHY IT MATTERS
Optimizes performance and cost-efficiency for LLM applications in BFSI, crucial for high-volume tasks like legal document review or customer service automation.
