Local-First AI Inference Cuts PDF Processing API Costs 75% Across 4,700 Documents
bibryam · x · 2026-09-12
An InfoQ article details the Local-First AI Inference architecture pattern for cost-effective document processing. On a real workload of 4,700 PDFs:
- Local extraction handled 70-80% of documents
- Cloud vision models handled only edge cases
- Human review covered about 5%
The result: API costs fell 75% and processing time dropped 55%. The core idea is a tiered pipeline—cheap local models do bulk triage, while expensive cloud capabilities and humans are reserved for the long tail.
