The efficacy of Large Language Models hinges critically on the quality and processing of their pretraining data. Current methods, however, often apply a one-size-fits-all strategy, failing to adapt to the unique characteristics of individual data examples. This limitation is addressed by DataOrchestra, a novel framework that moves beyond static approaches.

Orchestrating Example-Specific Pretraining Pipelines

DataOrchestra introduces a dynamic system where an 'orchestrator' analyzes each chunk of pretraining data. This orchestrator makes intelligent decisions on whether to discard the data, leave it untouched, or apply targeted cleaning operations. For data requiring cleaning, DataOrchestra selects from a suite of downstream operations, including programmatic edits and sophisticated LLM-based rewriting techniques. Crucially, for each rewriting step, it generates precise instructions executed by specialized tool models. This adaptive approach ensures that pretraining data is optimized at an granular level, moving away from uniform corpus-wide processing.

Demonstrated Performance and Efficiency Gains

The researchers validated DataOrchestra by pretraining models ranging from 0.5B to 7B parameters from scratch on web data processed through their framework. The results showed stable average performance improvements across 11 benchmarks when compared to models trained with individual data-processing methods. Furthermore, DataOrchestra proved effective in math continued pretraining, outperforming stronger processing baselines. A key benefit observed is its ability to reduce processing compute by intelligently skipping unnecessary downstream operations for certain data chunks, showcasing a significant efficiency advantage for DataOrchestra LLM pretraining.
