What is prompt caching? A plain-English guide for BFSI engineers.
Prompt caching is a technique where AI models reuse portions of previously processed input context (e.g., regulatory documents, historical transaction logs) to avoid recomputing the same embeddings, cutting latency and cost. E.g., a compliance team building an AI agent to summarise 10,000 historical KYC files caches the legal definition section once, then applies it to each file.
WHY IT MATTERS
Dramatically reduces cost of batch processing in BFSI (AML screening, regulatory reporting, portfolio analysis); enables real-time agent responses without token waste.
