Cost Optimization Tips
- Use OCR first - Extract text cheaply, then LLM for analysis
- Smaller images - Resize to 1024px max before sending
- Template-based - Use rules for consistent formats
- Batch processing - Group similar documents
- Output caching - Store results to avoid re-processing
- LLMs - Full LLM comparison
- Chatbots - Conversational extraction
