ITBench-AA

An AI agent benchmark testing incident response on real Kubernetes infrastructure, revealing that frontier models like Claude Opus 4.7 and GPT-5.5 resolve fewer than 50% of production failures.

What is ITBench-AA?

ITBench-AA (IT Benchmark - Autonomous Agents) is an evaluation framework that tests AI agents on complex, multi-step Kubernetes incident response tasks using real-world production infrastructure—measuring their ability to diagnose, troubleshoot, and resolve live system failures.

Why It Matters

Most AI benchmarks test isolated reasoning or coding skills. ITBench-AA evaluates end-to-end operational reliability in high-stakes infrastructure scenarios where mistakes have real costs.

Initial results (May 2026) show:

  • Claude Opus 4.7: 43% incident resolution rate
  • GPT-5.5: 38% incident resolution rate
  • Open-source models: <20% resolution rate

This reveals that even frontier models struggle with the complex, ambiguous, multi-domain reasoning required for production operations.

How It Works

1. Realistic Incident Scenarios

ITBench-AA presents agents with authentic failure modes:

  • Application crashes ("Pod repeatedly restarting with OOMKilled status")
  • Network issues ("Service A can't reach Service B across namespaces")
  • Resource exhaustion ("Node experiencing disk pressure, evicting pods")
  • Configuration errors ("Deployment manifest has incorrect environment variable")

2. Evaluation Criteria

Success requires:

  • Correct diagnosis (identify root cause, not just symptoms)
  • Minimal blast radius (don't break other services while investigating)
  • Complete resolution (system returns to healthy state)
  • Appropriate tool use (kubectl, logs, metrics, config inspection)
  • Time efficiency (resolve within SLA constraints)

3. Autonomous Operation

Unlike supervised benchmarks, agents must:

  • Choose which commands to run (no step-by-step guidance)
  • Interpret ambiguous error messages
  • Decide when to escalate vs. continue investigating
  • Validate that their fix actually worked

Real-World Example

Scenario: A critical payment processing service is down. Users report "502 Bad Gateway" errors.

Agent Task:

  1. Check pod status → discovers pods are running but not ready
  2. Inspect pod logs → sees "connection refused" errors to database
  3. Check database service → discovers it's in a different namespace
  4. Review network policies → finds policy blocking cross-namespace traffic
  5. Identifies root cause: Recent policy update blocked legitimate traffic
  6. Proposes fix: Add network policy exception for payment service
  7. Applies fix, validates pods become ready, confirms 502 errors stopped

Typical frontier model failures:

  • Misdiagnoses as application bug (ignores network layer)
  • Breaks production by restarting all pods without investigation
  • Gets stuck in analysis paralysis, never proposes a fix
  • Fixes the symptom (restarts pods) but not the root cause

Related Concepts

ITBench-AA builds on Agent Evaluation, Infrastructure-as-Code, and Observability. It complements JobBench (knowledge work) by focusing on infrastructure reliability and complements SWE-bench (software engineering) by focusing on operations.
