## Pricing for Vision Workloads

Vision models charge for image tokens. Each image is converted to tokens based on resolution:

### Approximate Tokens per Image

| Resolution | Approximate Tokens | GPT-4o Cost/Image | Claude Cost/Image |
|-----------|-------------------|-------------------|-------------------|
| 512x512 (thumbnail) | ~170 | $0.0009 | $0.0005 |
| 1024x1024 (standard) | ~765 | $0.004 | $0.002 |
| 2048x2048 (high-res) | ~1,100 | $0.006 | $0.003 |
| 4096x4096 (very high) | ~2,500+ | N/A (max 2048) | $0.008 |

### Cost Comparison: Document Processing

Processing 10,000 document images per day (average 1024x1024):

| Model | Daily Image Cost | Daily Text Output | Total Daily | Monthly |
|-------|-----------------|-------------------|-----------|---------|
| GPT-4o-mini | $1.15 | $0.30 | $1.45 | $43.50 |
