9 min read
Amazon Bedrock offers powerful AI capabilities, but without proper optimization, costs can quickly escalate. This guide provides strategies and best practices for optimizing costs when running AI workloads on Amazon Bedrock, including model selection and resource management.
Cost Optimization Impact
Proper optimization strategies can reduce Bedrock costs by 40-60% while maintaining or even improving performance.
Quick Comparison
| Aspect | Prompt Engineering | Fine-Tuning |
|---|---|---|
| Setup Time | Minutes to hours | Days to weeks |
| Cost | Low (API calls only) | High (training + hosting) |
| Data Required | Few examples | Hundreds to thousands |
| Flexibility | Very flexible | Fixed after training |
| Performance | Good for general tasks | Excellent for specific tasks |
Decision Framework
Use Prompt Engineering When:
- You need rapid prototyping
- Requirements change frequently
- Limited training data available
- Budget constraints exist
- General-purpose tasks
Use Fine-Tuning When:
- Domain-specific expertise needed
- Large dataset available
- Consistent output format required
- Lower latency critical
- Long-term stable requirements
Best Practices
Prompt Engineering Best Practices
Structure
- Use clear instructions
- Provide examples (few-shot)
- Define output format
Optimization
- Test iteratively
- Version control prompts
- Monitor performance
Fine-Tuning Best Practices
Data Preparation
- Clean and validate data
- Ensure diversity
- Balance dataset
Training
- Start with small datasets
- Monitor for overfitting
- Validate thoroughly
