| `llava` | 4GB | ✅ Working | Alternative |
| `llava-llama-3` | 8GB | ✅ Working | Best quality local |

### Performance:
- **Speed**: 5-30 seconds per image
- **Quality**: Good (depends on model)
- **Reliability**: Varies by model
- **Cost**: Free (but uses your hardware)

### Pros:
✅ Fully local (privacy)
✅ No API costs
✅ Works offline
✅ No rate limits

### Cons:
❌ Large downloads (7-20 GB)
❌ High RAM usage (8-16 GB)
❌ Slow inference (5-30s)
❌ Setup complexity
❌ Inconsistent results
❌ Hardware dependent

### Code Integration:

```python

## 💰 Cost Analysis

### Groq API Pricing:
- **Free Tier**: 1,000 requests/day
- **Paid**: $0.0007 per image (after free tier)
- **Example**: 100 images/day = ~$0.02/day = **$0.60/month**

### Local Model Costs:
- **Electricity**: ~$0.05-0.10 per hour of inference
- **Hardware**: If you need to upgrade RAM/GPU
- **Time**: Your time managing models

**Break-even point**: ~3 years of Groq API = cost of 16GB RAM upgrade

## 🚀 My Recommendation

### For Your Use Case: **Groq API**

**Why:**

1. **You're already using Groq** for text tasks
2. **No setup hassle** - just add API key
3. **Much faster** - 2s vs 30s per image
4. **Better quality** - 90B model vs 0.8-9B local
5. **Cost is negligible** - free tier covers most use cases
6. **Production-ready** - reliable, consistent

### When to Use Local Instead:

- You need **offline** processing
- You have **strict data privacy** requirements
- You're processing **10,000+ images/day** (cost adds up)
- You have **spare GPU/RAM** and want to experiment
