Basic Information

DataFlow is an open source data-centric AI system and toolkit for preparing, generating, processing and evaluating high-quality training and retrieval data for large language models. It is designed to take noisy sources such as PDFs, plain text and low-quality QA datasets and transform them into curated datasets suitable for pre-training, supervised fine-tuning, reinforcement learning and retrieval-augmented generation. The repository provides a modular operator abstraction, composable pipelines and an intelligent DataFlow-agent that can author operators and dynamically assemble pipelines to meet task objectives. The system is positioned for domain-oriented model improvement and has reported empirical validation in domains such as healthcare, finance and law. The project includes a CLI, Gradio web interfaces for operators and the agent, package installation instructions, and references to a managed SaaS deployment on an intelligent data platform.

App Details

Features
Modular operator architecture with many built-in operators including generic, domain-specific and evaluation operators. Ready-to-use pipelines such as Text extraction and QA mining, Reasoning enhancement, Text2SQL translation, Knowledge Base cleaning and Agentic RAG. An intelligent DataFlow-agent that analyzes tasks, writes or recombines operators and auto-orchestrates pipelines. Evaluation operators that assess data across multiple dimensions and metrics. Interactive Gradio web interfaces for exploring operators, pipelines and the agent. CLI tools and a Python package distributed as open-dataflow with optional vllm GPU support. Integration with external document extraction tooling for PDFs and multimodal data ingestion. Demo datasets and HuggingFace examples and experimental results for pretraining, SFT and Text2SQL workflows.
Use Cases
DataFlow helps practitioners and researchers turn noisy, unstructured source material into high-quality training and retrieval datasets that boost domain LLM performance. It automates common preprocessing tasks, extracts and structures knowledge from documents and tables, synthesizes QA pairs for supervised training and RAG, and augments existing data with reasoning chains, difficulty labels and schema-aware SQL generation. The built-in evaluation operators provide quantitative filters to select better pretraining and fine-tuning samples. The DataFlow-agent reduces manual pipeline design by recommending and composing operators. Interactive web UIs enable rapid experimentation and visualization. A managed SaaS option supports enterprise adoption and scalable compute while the open-source package supports local development and GPU inference workflows.
