 | [content_extraction.ipynb](notebooks/content_extraction.ipynb) | In this sample we will show content understanding API can help you get semantic information from your file. For example OCR with table in document, audio transcription, and face analysis in video. |
 | [field_extraction.ipynb](notebooks/field_extraction.ipynb) | In this sample we will show how to create an analyzer to extract fields in your file. For example invoice amount in the document, how many people in an image, names mentioned in an audio, or summary of a video. You can customize the fields by creating your own analyzer template. |
+| [content_understanding_pro_mode.ipynb](notebooks/content_understanding_pro_mode.ipynb) | In this sample we will demonstrate how to use **Pro mode** in Azure AI Content Understanding to enhance your analyzer with multiple inputs and optional reference data. Pro mode is designed for advanced use cases, particularly those requiring multi-step reasoning, and complex decision-making (for instance, identifying inconsistencies, drawing inferences, and making sophisticated decisions).|
 | [classifier.ipynb](notebooks/classifier.ipynb) | This sample will demo how to (1) create a classifier to categorize documents, (2) create a custom analyzer to extract specific fields, and (3) combine classifier and analyzers to classify, optionally split, and analyze documents in a flexible processing pipeline. |
 | [conversational_field_extraction.ipynb](notebooks/conversational_field_extraction.ipynb) | This sample shows you how to evaluate conversational audio data that has previously been transcribed with Content Understanding or Azure AI Speech in in an efficient way to optimize processing quality. This also allows you to re-analyze data in a cost-efficient way. This sample is based on the [field_extraction.ipynb](notebooks/field_extraction.ipynb) sample. |
 | [analyzer_training.ipynb](notebooks/analyzer_training.ipynb) | If you want to futher boost the performance for field extraction, we can do training when you provide few labeled samples to the API. Note: This feature is available to document scenario now. |
