Pricing Models Comparison
Detailed cost breakdown for both APIs
| Aspect | Gemini API | Vertex AI |
|---|---|---|
| Pricing Model | Per Request Pay per API call | Token-Based Pay for input/output tokens |
| Free Tier | 15 requests/minute 1,500 requests/day | Limited free credits $300 trial (new users) |
| Cost per Image | $0.00 Within free tier limits | ~$0.05-0.20 Varies by tokens used |
| Monthly Estimate (1,000 images) | $0 Well within free tier | $50-200 Depends on complexity |
| Monthly Estimate (10,000 images) | $0-50 May exceed free tier | $500-2,000 Significant cost at scale |
| Enterprise Pricing | Standard Contact for volume discounts | Negotiable Custom pricing available |
Cost Optimization Tips
- Gemini API: Maximize free tier usage by implementing request caching and rate limiting
- Vertex AI: Optimize prompts to reduce token consumption and use batch processing
- Monitor usage patterns to predict when you'll exceed free tier limits
