About Snorkel AI

Snorkel AI works with advanced AI teams to develop specialized datasets, evaluations, and environments for training and assessing modern models and agents. The company focuses on the data layer of AI development, where domain expertise and carefully constructed examples can help address gaps that generic model training data does not cover. Snorkel supports custom data development, expert demonstrations, preference labels, evaluation rubrics, benchmark expansions, and task-specific datasets. Its data-centric methods help teams build and assess systems for areas such as retrieval-augmented generation, structured extraction, classification, safety, and complex agent workflows, with subject matter experts contributing to quality and evaluation criteria. The company serves frontier AI labs and organizations building specialized AI systems that need high-quality training and evaluation data. Snorkel AI is relevant to AI data development, expert data services, model evaluation, benchmark creation, and scalable workflows for improving the reliability and performance of generative AI applications.
