Smart Iterative Refinement

How It Works

┌─────────────────────────────────────────────────────┐
│  1. Generate infographic with Nano Banana Pro       │
│                    ↓                                │
│  2. Review quality with Gemini 3.6 Flash            │
│                    ↓                                │
│  3. Score >= threshold?                             │
│       YES → DONE! (early stop)                      │
│       NO  → Improve prompt, go to step 1            │
│                    ↓                                │
│  4. Repeat until quality met OR max iterations      │

Review Log

Each generation produces a JSON review log:

{
  "user_prompt": "5 benefits of exercise...",
  "infographic_type": "list",
  "style": "healthcare",
  "doc_type": "marketing",
  "quality_threshold": 8.5,
  "iterations": [
    {
      "iteration": 1,
      "image_path": "figures/exercise_v1.png",
      "score": 8.7,
      "needs_improvement": false,
      "critique": "SCORE: 8.7\nSTRENGTHS:..."
    }
  ],
  "final_score": 8.7,
  "early_stop": true,
  "early_stop_reason": "Quality score 8.7 meets threshold 8.5"
}
