RBAC (Sharing)​

Share resources such as workflows, evaluations, or tests directly in the UI through integration with the Authz service.

MRM artifacts and actionability​

MRM Workflows now produce various output artifacts:

  • Summary and report: Generate a comprehensive workflow report to ingest and explore in H2OGPTe.
  • Corpus patch: A collection of FAQs based on problematic prompts and their expected answers to add to H2OGPTe collections to improve RAG performance.
  • Guardrails configuration: A downloadable configuration (JSON file) for custom guardrails to embed into applications using the H2O Eval Studio Python client.

New MRM features​

  • Introduced the following MRM workflow features:
    • Generated test validation: Validate the quality of the generated test suite using various metrics.
    • Failure clustering: Automatically detect common failure patterns of the model host.
    • Workflow statuses: Every workflow step now can report various colored statuses, such as failures, warnings, or being stale, indicating the need to verify outputs and re-run certain steps for up-to-date results.
  • MRM workflows now support other model hosts, including Bedrock and OpenAI-compatible APIs.
  • MRM workflows are now accessible directly through H2OGPTe collection UI.
  • Improved UX for workflows and their individual steps, including enhancements for robustness testing.
