proxima-ocr-d.markdown-post3.0.l

proxima-ocr-d.markdown-post3.0.l is an experimental document AI multimodal model fine-tuned on top of Qwen3-VL-8B-Instruct, optimized for high precision OCR and structured document reconstruction. The model converts documents into Markdown, HTML-Markdown, and hybrid enriched documentation formats capable of embedding inline programming languages and reconstructing complex layouts such as tables, forms, and mathematical content.

Key Enhancements

• Dynamic Markdown Reconstruction Converts complex documents to structured Markdown or HTML-Markdown while preserving layout hierarchy, formatting consistency, semantic ordering, and section alignment.

• Inline Code and Language Embedding Direct adaptation of Python, JavaScript, LaTeX, and shell syntax into reconstructed documents for technical and research documentation.

• High Fidelity OCR and Visual Parsing Accurate recognition of text across structured and unstructured scanned documents, including multi page layout reasoning.

• Complex Layout Interpretation Interprets tables, grids, equations, graphs, multi column layouts, and forms without structural distortion.

• Document Retrieval and Semantic Linking Efficient multi page chunking with cross reference recognition and content traceability.

• Multimodal Long Reasoning Supports advanced document question answering and reasoning across long input streams such as slides and manuscripts.

Quick Start with Transformers

from transformers import Qwen3VLForConditionalGeneration, AutoProcessor
from qwen_vl_utils import process_vision_info

model = Qwen3VLForConditionalGeneration.from_pretrained(
 "prithivMLmods/proxima-ocr-d.markdown-post3.0.l", torch_dtype="auto", device_map="auto"
)

processor = AutoProcessor.from_pretrained("prithivMLmods/proxima-ocr-d.markdown-post3.0.l")

messages = [
 {
 "role": "user",
 "content": [
 {
 "type": "image",
 "image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen-VL/assets/demo.jpeg",
 },
 {"type": "text", "text": "Convert to Markdown."},
 ],
 }
]

text = processor.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
image_inputs, video_inputs = process_vision_info(messages)
inputs = processor(
 text=[text],
 images=image_inputs,
 videos=video_inputs,
 padding=True,
 return_tensors="pt",
)
inputs = inputs.to("cuda")

generated_ids = model.generate(**inputs, max_new_tokens=2048)
generated_ids_trimmed = [
 out_ids[len(in_ids):] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)
]
output_text = processor.batch_decode(
 generated_ids_trimmed, skip_special_tokens=True, clean_up_tokenization_spaces=False
)
print(output_text)

Intended Use

• OCR to Markdown or HTML-Markdown conversion
• Complex document reconstruction and formatting regeneration
• Multi page document reasoning and retrieval
• Table extraction and structured output transformation
• Mathematical OCR and LaTeX conversion
• Form extraction and structured entity generation
• Knowledge base indexing and large document QA
• Documentation regeneration for enterprise automation

Limitations

• Accuracy may drop on extremely damaged or poorly scanned images
• Significant GPU VRAM required for long sequences and multi page documents
• Language accuracy varies for low resource scripts
• Complex objects such as mixed orientation blocks may require secondary post processing
• May occasionally produce formatting misalignment in highly irregular layouts
