Practical thinking for teams building AI with data.
Field guides on collection, annotation, preference data, evaluation, synthetic generation and enterprise dataset operations.
How frontier AI companies build datasets
A practical operating model for turning model failures, product goals and evaluation evidence into high-value training data.
Read the guide ↗Build better data systems.
Why high-quality data can beat a bigger model
More parameters cannot repair ambiguous labels, missing edge cases or evaluation sets that reward the wrong behaviour.
03AI evaluationRLHF explained: from preference data to better model behaviour
What preference data, rubrics, reviewer calibration and disagreement analysis actually contribute to an RLHF program.
04Synthetic dataSynthetic data vs. human data: where each one wins
A decision framework for choosing generated, collected or hybrid data without hiding provenance or quality risk.
05Enterprise governanceBuilding enterprise AI datasets that survive procurement
The documentation, governance and operating controls enterprise buyers expect before model-ready data can be trusted.
06Annotation qualityThe hidden cost of poor labels
Why annotation defects multiply across training, evaluation, debugging and product operations long after delivery.
