CATEGORY GUIDE
Training data providers
Datasets for pretraining, fine-tuning, and domain adaptation.
A training-data engagement can deliver a reusable corpus, a custom collection, or a stream of examples. Ask how records were obtained, what the license permits, and how quality is measured. A large row count alone tells you little about useful coverage.
