N8n semantic cache workflow

★ 6.6 · n8n · medium · 14 nodes

N8n semantic cache workflow is an n8n automation template that implements semantic caching for language model queries: instead of calling an LLM repeatedly, the system looks for a semantically similar answer in the cache and returns it directly. Reach for it when LLM API costs are growing because users ask the same questions in different wordings, when chatbot response times need to improve without sacrificing quality, or when you want to reduce load on rate-limited endpoints.
