A developer significantly reduced API costs for processing PDFs by splitting tasks between different Anthropic Claude models. By using the more affordable Claude Haiku 4.5 for optical character recognition (OCR) on image-heavy documents and the more capable Claude Sonnet 4.6 for subsequent concept extraction and structuring, costs were cut by approximately 80%. This approach leverages Haiku's efficiency for simple transcription and Sonnet's power for complex analysis, demonstrating a practical strategy for optimizing LLM usage based on task complexity. AI
