Executive Summary

Kodezi Chronos achieves breakthrough performance in autonomous debugging:

Key Achievements:

  • 67.3% debugging success rate (4.87x better than Claude 4 Opus)
  • 78.4% root cause accuracy (5x better than baselines)
  • 2.2 average fix cycles (2.3x faster than competitors)
  • $1.36 cost per success (4.5x more cost-effective)

These metrics represent evaluation on 5,000 real-world debugging scenarios across diverse codebases, validated through statistical analysis (p < 0.001).

Benchmark Methodology

Evaluation Framework

Dataset Composition:

  • 5,000 debugging scenarios from production repositories
  • 3 programming languages: Python (40%), JavaScript (35%), Java (25%)
  • Repository sizes: 1K to 10M+ lines of code
  • Bug sources: GitHub issues, Stack Overflow, internal bug trackers

Multi Random Retrieval (MRR) Benchmark

Our novel benchmark better reflects real-world debugging complexity:

MRR Characteristics:

  • Context scattering: Relevant files distributed across 10-50 locations
  • Temporal dispersion: Code written over 3-12 months
  • Obfuscated dependencies: Non-obvious relationships between components
  • Realistic complexity: Mirrors production debugging challenges

Evaluation Metrics

Primary Metrics:

  1. Success Rate: Percentage of bugs fixed correctly
  2. Root Cause Accuracy: Correct identification of bug source
  3. Fix Cycles: Number of attempts to reach solution
  4. Token Efficiency: Tokens consumed per successful fix
  5. Time to Resolution: End-to-end debugging time

Validation Criteria:

  • All tests must pass
  • No regression introduction
  • Code style consistency maintained
  • Performance not degraded
