Turbo-OCR hits 1,200 img/s with C++/CUDA

Turbo-OCR is a high-performance C++/CUDA inference server designed for massive document processing. By bypassing Python overhead and utilizing TensorRT, it achieves 100x-500x higher throughput than standard PaddleOCR implementations, making it an ideal "pre-filter" for large-scale RAG pipelines and document indexing where speed is the primary constraint.

// ANALYSIS

Turbo-OCR ruthlessly targets the "Python tax" in document AI, trading layout complexity for massive raw throughput.

–Engineered in C++20 and CUDA to eliminate GIL overhead and maximize GPU utilization to 99% on modern NVIDIA hardware.
–Multi-stream pipeline architecture allows parallel processing of detection and recognition stages, hitting 1,000+ img/s on sparse documents.
–Optimized for Blackwell and Ada Lovelace GPUs using TensorRT FP16, providing a high-speed alternative to expensive and slow VLM-based OCR.
–Developed using AI coding assistants to bridge the gap between high-level OCR models and low-level systems performance.
