-# granite-docling-258M ONNX
-ONNX conversion of IBM's granite-docling-258M vision-language model for high-performance document understanding in Rust applications.
-## Model Details
-- **Base Model**: [ibm-granite/granite-docling-258M](https://huggingface.co/ibm-granite/granite-docling-258M)
-- **Format**: ONNX (Opset 17)
-- **Size**: 1.2GB
-- **License**: Apache 2.0
-- **Architecture**: Idefics3-based VLM (SigLIP2 vision + Granite 165M language)
-## Key Features
-✅ **Document Understanding**: Complete document structure analysis
-✅ **DocTags Output**: Structured markup preserving layout, tables, equations
-✅ **High Performance**: 2-5x faster inference than PyTorch
-✅ **Rust Compatible**: Works with ONNX Runtime (ORT) crate
-✅ **Production Ready**: Validated conversion with IBM experimental tools
-## Quick Start
-### ONNX Runtime (Python)
 ```python
 import onnxruntime as ort
 import numpy as np
-# Load model
 session = ort.InferenceSession('model.onnx')
-# Prepare inputs (example dimensions)
 input_ids = np.array([[1, 2, 3, 4, 5]], dtype=np.int64)
 attention_mask = np.ones((1, 5), dtype=np.int64)
-pixel_values = np.random.randn(1, 3, 512, 512).astype(np.float32)
 # Run inference
 outputs = session.run(None, {
     'input_ids': input_ids,
-    'attention_mask': attention_mask,
-    'pixel_values': pixel_values
 })
-print(f"Generated logits: {outputs[0].shape}")
 ```
-### Rust ORT Integration
 ```rust
-use ort::{Session, inputs};
 // Load granite-docling ONNX model
 let session = Session::builder()?
     .with_optimization_level(GraphOptimizationLevel::Level3)?
-    .commit_from_file("granite-docling-258M-onnx/model.onnx")?;
-// Prepare document image (512x512)
-let document_image = prepare_document_image(pdf_page)?;
-// Run inference
-let outputs = session.run(inputs![document_image])?;
-// Process DocTags output
-let doctags = decode_doctags(outputs)?;
-```
-## Input Requirements
-- **pixel_values**: Document images resized to 512×512, normalized for SigLIP2
-- **input_ids**: Text token sequence (prompt for document processing)
-- **attention_mask**: Attention mask for text tokens
-## Output Format
-The model generates **DocTags** - a structured XML markup format for documents:
 ```xml
 <doctag>
-  <text><loc_100><loc_50><loc_400><loc_100>Document Title</text>
   <otsl>
-    <ched>Column 1<ched>Column 2<nl>
-    <fcel>Data 1<fcel>Data 2<nl>
   </otsl>
-  <formula>E = mc^2</formula>
 </doctag>
 ```
-## Conversion Details
-This ONNX model was converted using IBM's experimental Idefics3Support optimum-onnx fork:
 - **Source**: [gabe-l-hart/optimum-onnx@Idefics3Support](https://github.com/gabe-l-hart/optimum-onnx/tree/Idefics3Support)
-- **Patches Applied**: Position embedding and pixel shuffle fixes
-- **Validation**: Functional testing with ONNX Runtime 1.23
-- **Date**: September 27, 2025
-## Performance
-- **Inference Speed**: 2-5x faster than PyTorch (CPU/GPU)
-- **Memory Usage**: 60-80% less than PyTorch runtime
-- **Hardware Support**: CPU, CUDA, DirectML, TensorRT
-- **Deployment**: Single 1.2GB file, no dependencies
