Validation

Understand the impact of model and system changes with our test suite before you go to production.

How Arthur fits in:

  • Crafts an automated test suite from datasets with intelligent success criteria
  • Expedites the human-in-the-loop validation cycle by probing models for failure modes
  • Periodically validates models for resiliency to model changes outside their control

Safety

Prevent bad user experience and reputational impact from anomalous and malicious prompt inputs.

How Arthur fits in:

  • Provides deployment gates to identify anomalous inputs, PII leakage, toxicity, and other quality metrics
  • Learns from production performance to optimize thresholds for those quality gates

Control

Identify and analyze user feedback and model performance problems to drive better outcomes.

How Arthur fits in:

  • Provides core token-level observability, performance dashboarding, inference debugging, and alerting
  • Collects and analyzes implicit and explicit human feedback to monitor the model’s real-world impact
  • Accelerates ability to identify and debug underperforming regions
