Use Surya hOCR for Free

Surya hOCR is an AI model released 2024 by vikp, a leading organization in large language model research. Surya's high-accuracy OCR — extracts text with bounding boxes from scanned pages, screenshots, and photos in 90+ languages. With a large number of parameters and a a large context window context window, Surya hOCR is designed to excel across a range of demanding tasks — from software engineering and mathematical problem-solving to multilingual content generation and long-document analysis.

Surya hOCR uses a dense transformer architecture with a large number of parameters of parameters, all of which are active for every input token. Dense architectures provide predictable, consistent behavior across diverse task types — there are no "cold" experts to warm up, and quality is uniform across prompts. vikp's training pipeline combined large-scale pretraining on a large-scale multilingual pretraining dataset with supervised fine-tuning and alignment techniques (RLHF or DPO), producing Surya hOCR's characteristic balance of capability, helpfulness, and safety.

As of 2026-10-16, Surya hOCR by vikp demonstrates measurable performance on standard AI evaluation benchmarks. On Average OCR Accuracy — which measures model performance on specialized evaluation tasks — it achieves 92.3%. These scores place Surya hOCR in a competitive position within its model class. Note that benchmark scores reflect controlled evaluation conditions; real-world performance varies by task, prompt design, and domain specificity.

The primary strengths of Surya hOCR are: Multilingual OCR across 90+ languages; Layout analysis: tables, columns, headers; GPL-3.0 open source. These make it particularly well-suited for Multilingual document OCR in 90+ languages, Complex layout document parsing, Academic paper extraction. Users working on complex, multi-step problems benefit most from Surya hOCR's ability to maintain coherence across long inputs and produce structured, verifiable outputs.

Like all current AI systems, Surya hOCR has limitations: GPL-3.0 license limits some commercial use cases; Slower than simpler OCR models. For production deployments, validating outputs against authoritative sources — especially for domain-specific or time-sensitive information — remains best practice. vikp continues to improve Surya hOCR through ongoing research.

Surya hOCR is available on LITHOVEX AI with a free account. Unlike direct API access — which requires billing setup, API key management, and per-token charges — LITHOVEX AI provides a seamless browser interface with no setup required, making Surya hOCR accessible to students, researchers, developers, and early-stage teams globally.

OCR pipeline using Surya: detection + recognition + layout analysis

The training pipeline for Surya hOCR involves multiple stages: large-scale pretraining on diverse multilingual text and code corpora to develop broad world knowledge, followed by supervised fine-tuning on instruction-response pairs, and alignment techniques such as RLHF or DPO. Each stage refines the model's helpfulness, accuracy, and safety. vikp's research team — based in International — has optimized Surya hOCR for the specific capability profile described above.

Inference efficiency: Surya hOCR is designed to deliver quality outputs at practical serving speeds. Its context capacity supports complex multi-turn conversations without quality degradation.

Getting started with Surya hOCR on LITHOVEX AI takes under two minutes. Follow these steps:

For best results with Surya hOCR: provide specific, context-rich prompts; include examples when generating code; specify output format when structure matters; break complex tasks into focused sub-questions.
