Use Case Recipes
Recipes are a collection of code examples that demonstrate how to leverage Data Designer in specific use cases. Each recipe is a self-contained example that can be run independently.
New to Data Designer?
Recipes provide working code for specific use cases without detailed explanations. If you’re learning Data Designer for the first time, start with our tutorial notebooks, which offer step-by-step guidance and explain core concepts. Once you’re familiar with the basics, return here for practical, ready-to-use implementations.
Prerequisite
These recipes use the OpenAI model provider by default. Ensure your OpenAI provider is set up via the Data Designer CLI before running a recipe.
Code Generation
Natural-language instructions paired with Python implementations across complexity levels and industries.

VLM Long-Document Understanding
A 9-recipe pipeline for generating visual QA training data from long PDF documents: OCR, page classification, single-page / multi-page / whole-document QA, and frontier-model quality filtering.
Download PDFs, render page images, and prepare seed datasets for the downstream VLM recipes.
Run Nemotron Parse over document pages and save OCR transcripts for text-based QA generation.
Generate text-grounded question-answer pairs from OCR transcripts.
Classify pages by visual reasoning potential before running more expensive QA generation.
Generate visual question-answer pairs from classified page images.
Generate single-page VLM QA examples from page-level image seeds.
Generate cross-page QA examples over fixed-size page windows.
Generate document-level QA examples over grouped page images.
Score and filter generated QA pairs with a stronger independent judge.
