Composable blocks and flows for synthetic data generation

---

SDG Hub is a Python framework for building synthetic data generation pipelines. Chain LLM, parsing, transform, filtering, and agent blocks into YAML-defined flows -- then generate training data at scale.

Get Started

pip install sdg-hub

from sdg_hub import FlowRegistry, Flow

# Discover and load a built-in flow
FlowRegistry.discover_flows()
flow = Flow.from_yaml(FlowRegistry.get_flow_path("MCP Server Distillation"))

# Configure and run
flow.set_model_config(model="openai/gpt-4o")
result = flow.generate(dataset)

See the Quick Start for a full walkthrough, or browse all built-in flows.
