Designing End-to-End Data Pipelines for AI Training
Architecture patterns for production AI data pipelines — from ingestion to model-ready datasets.
By Tbrain Team
The Pipeline Problem
Data preparation is a continuous pipeline that runs alongside model development.
Architecture Components
1. Ingestion Layer
Raw data from multiple sources: web scraping, uploads, partner feeds. Normalizes formats and deduplicates.
2. Annotation Layer
- Task distribution and load balancing
- Multi-tier quality control
- Version-controlled guidelines
- Real-time progress tracking
3. Validation Layer
- Schema compliance checks
- Statistical distribution analysis
- Inter-annotator agreement scoring
4. Delivery Layer
Packaged in model-ready formats (JSONL, TFRecord, Parquet) with full provenance.
A data pipeline is not a script. It is a production system.
