  • Release version: Zurich
  • Updated April 8, 2026
  • 2 minutes to read
  • View all evaluated AI sessions across your portfolio, compare quality and safety scores by AI system, and identify the sessions that need investigation.

    Key benefits

    • Compare quality and safety scores across AI systems to identify which systems are declining or performing well.
    • Find low-scoring sessions quickly by sorting and filtering the session list.
    • View score trends by AI system over weeks or months to detect patterns.
    • Open any session directly to investigate its traces and spans.

    Required roles

    The AI Asset Owner or AI Steward role is required to view evaluated sessions.

    Accessing evaluated sessions

    View evaluated sessions by navigating to All > AI Control Tower > Home > Insights > Monitor and selecting the Evaluated sessions tab.

    AI systems with evaluated sessions

    Compare quality and safety scores across your AI systems using the bar chart. Each AI system displays a pair of bars representing its quality and safety scores.

    • Group scores by Months, Weeks, or Days to adjust the time granularity.

      For example, after deploying an update to an AI system, group the chart by Days to see whether the update improved scores without affecting other systems.

    • Select Largest score decline or Top performers from the list to change how AI systems are sorted in the chart.

    Evaluated sessions list

    Find the sessions that need attention by reviewing the evaluated sessions table. Scores are color coded for quick scanning: red (0 to 50%), orange (51 to 75%), green (76 to 100%).

    Name
    Session identifier. Select the name to open the session detail page and begin investigating traces and spans. See Investigate a low-scoring session.
    Traces
    Number of traces in the session. A session with many traces represents a longer, multi-turn interaction. Low scores on sessions with few traces can indicate a fundamental issue, while low scores on sessions with many traces may point to degradation over the course of the conversation.
    AI system
    The AI system associated with the session. Select the name to view aggregated quality and safety scores across all evaluated sessions for that system.
    Quality score
    Composite quality score for the session, calculated from the weighted metrics in your quality template. Sort by this column to surface the lowest-scoring sessions first.
    Safety score
    Composite safety score for the session, calculated from the weighted metrics in your safety template. A red safety score warrants immediate investigation.
    Start time
    When the session began. Use this to correlate low scores with known events such as deployments, configuration changes, or outages.
    End time
    When the session ended or timed out.
    Total runtime tokens
    Combined input and output tokens consumed by the AI system during this session. This reflects the cost of running the interaction, not the cost of evaluating it. Unusually high token counts can indicate inefficient agent behavior such as excessive retries or overly verbose responses.
