# Nanonets-OCR2-3B Vision Language Model
# Based on Qwen2.5-VL-3B, fine-tuned for document OCR (Oct 2025 release)
# Improvements over OCR-s: better semantic tagging, LaTeX equations, flowcharts
# ~12-16GB VRAM with 30K context, outputs structured markdown with semantic tags
#
# Build: docker build -f Dockerfile_nanonets_vllm_gpu_VRAM10GB -t nanonets-ocr .
# Run:   docker run --gpus all -p 8000:8000 -v ht-huggingface-cache:/root/.cache/huggingface nanonets-ocr
