A thread breaks down ten practical ways to cut an AI API bill without reducing output quality.
Key tactics include prompt caching, batching non-urgent jobs, capping output tokens, routing easy work to cheaper models, compacting context, trimming RAG top-k, stopping runaway generation, delegating heavy subtasks to subagents, and caching repeated answers at the app layer. The author claims stacking the techniques can reduce spend by up to 90%.
