## Parallel vs Sequential

```
Sequential (litellm/OpenRouter/etc):
  Request → Try GPT-4o ($0.03) → ❌ fail
          → Try Claude ($0.003) → ❌ fail
          → Try Groq ($0.00006) → ✅ success
  Result: 3 API calls, 3× latency, $0.033 cost

Parallel (A3M):
  Request → GPT-4o ═╗
           → Claude ═╣ → Score each → Pick best by confidence
           → Groq   ═╝
  Result: 1 round-trip, 1× latency, $0.00006 cost

Same answer quality. 550× cheaper. 3× faster.
