Data Designer helps you create synthetic datasets that go beyond simple LLM prompting. Whether you need diverse statistical distributions, meaningful correlations between fields, or validated high-quality outputs, Data Designer provides a flexible framework for building production-grade synthetic data. What can you do with Data Designer? - Generate diverse data using statistical samplers, LLMs, or existing seed datasets - Control relationships between fields with dependency-aware generation - Validate quality with built-in Python, SQL, and custom local and remote validators - Score outputs using LLM-as-a-judge for quality assessment - Iterate quickly with preview mode before full-scale generation --- 📣 Heads-up: async engine Data Designer now runs pipelines on a cell-level async engine that overlaps independent columns and adapts concurrency per (provider, model). On most pipelines this is faster with no config changes; on slow self-hosted endpoints, set inference parameters.timeout to your real per-request latency. See Architecture & Performance → Async Engine for the behaviors worth knowing about. If you hit anything unexpected, please open an issue. --- Quick Start 1. Install Or install from source: 2.
