Datalab's Indra OCR Parses 49 Pages per Second on a CPU
Datalab's new 1M-parameter Indra OCR reads 49 pages per second on CPU, outpacing Tesseract and PaddleOCR while keeping layout and reading order intact.
- Datalab released Indra OCR, a 1M-parameter CPU OCR model under Apache 2.0.
- Hits 49 pages/sec on 32 cores, 11-17x faster than Tesseract and PaddleOCR.
- Scores 41.3 on OmniParseBench text vs 35.8 PaddleOCR and 19.3 Tesseract.
- Outputs markdown, plain text, or JSON with layout blocks, boxes, and reading order.
- Only 18 MB of ONNX weights, no PyTorch; weights on Hugging Face.
- Weak on handwriting, complex tables, degraded scans, and non-supported scripts.
Indra OCR parses documents with a 1-million-parameter recognizer
Datalab has released Indra OCR, a compact document-conversion stack that runs on CPUs and turns PDFs or images into Markdown, plain text, or structured JSON. Its output can include line-level bounding boxes, labeled layout blocks, reading order, and confidence scores.
Modern document parsers often use vision-language models that render each page as an image and generate text token by token, increasing memory use and latency. Indra targets high-volume ingestion jobs such as preparing documents for retrieval-augmented generation, indexing scanned archives, and routing difficult pages to larger models.
The repository code uses the Apache 2.0 license. The model weights use a modified OpenRAIL-M license that permits free research use and free use by startups with less than $20 million in funding or revenue. Organizations outside those terms should review the model license before deployment.
49 pages per second, under test
On a 32-core AMD EPYC system, Datalab reports processing 300 OmniParseBench pages at 49 pages per second. A 4-vCPU configuration averaged roughly 230 milliseconds of latency per page.
