Scenario: LLM Inference Cost vs Latency Tradeoffs

"You are building an AI-powered product and must choose between Option A (higher cost, lower latency) and Option B (lower cost, higher latency). How would you decide?"

The Decision Framework

OPTION A: Premium Model (e.g., GPT-4, Claude Opus, Gemini Pro)
Cost: $15-75 / 1M tokens | Latency: 500ms-3s TTFT | Quality: Highest

OPTION B: Efficient Model (e.g., GPT-4o-mini, Claude Haiku, Gemini Flash)
Cost: $0.25-3 / 1M tokens | Latency: 100ms-500ms TTFT | Quality: Good

THE REAL ANSWER: Use both. Route dynamically.
