│ FALLBACK STRATEGY │

└──────────────────────────────────────────────────────────────────────────────┘
|
|
|
|
If optimization fails:
|
|
|
|
1. Deploy 3-model ensemble (DQN + PPO + MAMBA-2)
|
|
→ All models meet <5ms P95 latency target
|
|
→ Total GPU memory: 315MB (well under 4GB budget)
|
|
|
|
2. Use TFT for batch predictions (non-latency-critical)
|
|
→ Batch size = 8 → 1.76ms per sample throughput
|
|
→ 570 samples/sec (acceptable for non-real-time use)
|
|
|
|
3. Defer TFT real-time to GPU upgrade (8GB+ VRAM)
|
|
→ RTX 4060 Ti (8GB) or RTX 4070 (12GB)
|
|
→ Cost: $300-400 hardware investment
