Snorkel AI

platform active freemium

A data-centric AI platform focused on programmatic labeling and data development. Snorkel pioneered weak supervision - using labeling functions to programmatically generate training labels instead of manual annotation. Their enterprise platform extends this with LLM-assisted labeling and data quality tools.

Implements

Concepts this tool claims to implement:

  • Programmatic data labeling with labeling functions. Weak supervision to combine noisy label sources. LLM-assisted label generation for scaling annotation.

  • Data slicing and analysis. Error analysis on model predictions. Data versioning and lineage tracking.

  • Annotation secondary

    SME (subject matter expert) labeling interface. Combine programmatic and human labels. Label model for denoising and combining sources.

Integration Surfaces

  • Python SDK (snorkel)
  • Snorkel Flow (enterprise platform)
  • REST API
  • Web interface

Notes

Snorkel is unique in its focus on programmatic labeling. The open-source library implements weak supervision concepts. Snorkel Flow is the enterprise platform with more features. Good for teams that can write labeling functions rather than relying purely on manual annotation.
