6-Layer API Cost Compression Formula

High model bills aren't solved by calling less — they're solved at the architecture level. This breakdown covers a 6-layer cost compression formula: prompt trimming, tiered model routing, semantic caching, batch async processing, and more. Routing simple classification tasks to Haiku 4.5 instead of Opus 4.8 can mean a 20x cost difference. A 10% boost in cache hit rate typically cuts your total bill by around 15%. These are real numbers, not theory. Want to switch between GPT-5.4, Claude, DeepSeek, Gemini 3, and 200+ models through a single API? XycAi has you covered.
