DataFlow

DataFlow is a data preparation and training system that generates, refines, evaluates, and filters data for large language model development pipelines.

DataFlow is a data preparation and training system designed to generate, refine, evaluate, and filter data from noisy sources like PDF, plain-text, and low-quality QA to improve LLM performance. It utilizes an operator-based architecture where users construct reproducible, reusable, and shareable pipelines for data governance tasks including text, math, and code generation. The suite includes a visual interface via the DataFlow-WebUI and an intelligent agent that dynamically assembles new pipelines from existing operators. The system supports large-scale orchestration through Ray and processes data in standard formats such as JSON, JSONL, and CSV. Designed for researchers and enterprises, it enables users to analyze the relationship between data quality and model performance across domains like healthcare, finance, and legal research.
