Building DataFlow: An Industrial‑Grade LLM Data Pipeline from Documents to Training
The article presents DataFlow, an open‑source, GPU‑centric data‑engineering framework that tackles LLM data‑preparation bottlenecks by defining a two‑level operator taxonomy, a LLM‑driven WebAgent for automatic crawling, a PDF‑to‑Markdown MinerU, a Ray‑based distributed runtime, and extensive multimodal extensions, and validates the design with quantitative experiments showing significant quality gains across math, code, and reasoning benchmarks.
