📊 Performance Benefits

Without Batching

• Load models (30s) → Generate (25s) → Unload
• Repeat for each prompt
• 8 prompts = ~7 minutes 20 seconds

With Simple Prompt Batcher

• Load models once (30s) → Generate all 8 (8 × 25s)
• Models stay loaded between generations
• 8 prompts = ~3 minutes 50 seconds

Result: ~50% time savings on batch processing! 🎯
