Production Best Practice: RAG architectures benefit tremendously from Prompt Caching. By pinning the shared system prompt and static chunk headers at the front of the context, 80%+ cache hit rates are achievable, cutting input token spend by up to 90%. Use hybrid routing: direct simple single-hop queries to efficient budget models while reserving reasoning models for synthesis.
Workload Architecture FAQs
How does prompt caching benefit a RAG Document QA Pipeline?
In a RAG Document QA Pipeline, system instructions, schema definitions, and RAG context chunks frequently repeat. Setting a cache hit rate of 75% reduces effective input token spend by up to 68%, providing dramatic margin improvements.
Why is Claude 3.5 Sonnet vs GPT-4o recommended for this architecture?
Claude 3.5 Sonnet and GPT-4o represent the production sweet spot for Enterprise Search & Retrieval. Claude 3.5 Sonnet provides premier accuracy, while GPT-4o offers high throughput unit economics for routine turns.
Should RAG Document QA Pipeline use the 24-hour asynchronous Batch API?
No. RAG Document QA Pipeline typically requires sub-second conversational or real-time latency SLAs, which necessitates standard on-demand inference endpoints.
How do conversation turns compound token costs in this workflow?
With 2 turn(s) configured per session, context accumulates as previous query/response history is re-sent. Careful management of context window and truncation keeps token inflation linear rather than quadratic.
