-Model:OCR box to json 
+Model Architecture
+The mychen76/mistral7b_ocr_to_json_v1 (LLM) is a finetuned for convert OCR text to Json object task. this experimental model is based on Mistral-7B-v0.1 which outperforms Llama 2 13B on all benchmarks tested.
+
+Motivation 
+current OCR engines are well tested on image detection and text recognition. LLM model are well train for text process and generation. 
+Hence, leveraging output from OCR engine could save LLM training time for image-to-text use case such as invoice or receipt image to json object convertion task.
 
 Model Usage:
+Take a random receipt image picture, perform Image OCR to get text boxes then feed into LLM model to generate as well-pformed receipt json object. 
+
 ```
