DeepSeek-OCR 3B Vision Language Model Deployment Guide | Fine-tuning Vision Transformer for Document AI

DeepSeek-OCR: How to Run & Fine-tune for Real-World Document Intelligence How can you effectively deploy and customize DeepSeek-OCR, a 3B-parameter vision model, to achieve production-grade document understanding with minimal resource overhead? The answer lies in understanding its unique architecture—contextual optical compression that converts 2D layouts into efficient vision tokens—and leveraging two distinct but complementary deployment paths: vLLM for service-oriented stability and Unsloth for performance-optimized inference. This guide walks through both approaches, then demonstrates how just 60 training steps on a domain-specific dataset can slash error rates by 88%, turning a capable generalist into a highly accurate specialist.
