A benchmark study comparing a 3-billion-parameter specialized OCR model (DharmaOCR) against major commercial frontier APIs reveals that specialization through fine-tuning can outperform larger models on quality, cost, and production stability. The specialized 3B model scored 0.911 versus Claude Opus 4.6's 0.833, while costing roughly 52x less per million pages. The key finding is that distributional alignment — how closely a model's training history matches its deployment task — is a more decisive variable than parameter count. Evidence also shows specialization compounds: starting from a domain-adjacent base model before fine-tuning produces materially better results than starting from a general-purpose model. The article argues enterprise AI procurement should treat training history alignment as a first-class evaluation variable alongside model scale.
