# s57_a002

Genesis model routing hierarchy (cheapest to most expensive): Gemini Flash $0.15 (bulk/fast) → DeepSeek-R1 Distill $0.12 (fast reasoning) → DeepSeek-R1 $0.55 (deep strategy) → Kimi K2.5 $1.07 (agentic) → Haiku $1.00 (extractions) → Sonnet $9.00 (coordination) → Opus $15.00 (architecture only). NEVER use Opus for tasks DeepSeek-R1 can handle.
