  • Governs AI from any vendor, not only models built in IBM tools
  • Prebuilt regulatory frameworks including the EU AI Act and NIST AI RMF
  • Consolidates OpenScale, AI Factsheets and OpenPages model risk into one service
  • Flexible deployment across SaaS, AWS Marketplace and on-premises
  • Strong monitoring for fairness, bias, drift and performance
Cons
  • Aimed at ML/security engineers, not business or non-technical users

  • Free and Premium tiers cap use cases, data retention, and volume
  • Full-value deployment requires meaningful data/model integration work
  • Pricing is largely quote-based and can be opaque for buyers
