-  Large Language Models (LLMs) have advanced code generation and software automation, 
-  but are fundamentally constrained by limited inference-time context and lack of 
-  explicit code structure reasoning. We introduce Kodezi Chronos, a next-generation 
-  architecture for autonomous code understanding, debugging, and maintenance, designed 
-  to operate across ultra-long contexts comprising entire codebases, histories, and 
-  documentation—all without fixed window limits. Kodezi Chronos leverages a multi-level 
-  embedding memory engine, combining vector and graph-based indexing with continuous 
-  code-aware retrieval. This enables efficient and accurate reasoning over millions 
-  of lines of code, supporting repository-scale comprehension, multi-file refactoring, 
-  and real-time self-healing actions. Chronos achieves 67.3% debugging success rate, 
-  representing a 4-5x improvement over state-of-the-art models including Claude Opus 4 and GPT-4.1.

+### Overall Performance
+
+| Rank | System | Success Rate | Instances Resolved | Year |
+|------|--------|--------------|-------------------|------|
+| 🥇 **1** | **Kodezi Chronos** | **80.33%** | **241/300** | **2025** |
+| 🥈 2 | ExpeRepair-v1.0 + Claude 4.5 Sonnet | 60.33% | 181/300 | 2025 |
+| 3 | Claude 4.5 Sonnet (Bash Only) | ~14% | ~42/300 | 2025 |
+| 4 | Claude 4.1 Opus (Bash Only) | 14.2% | 43/300 | 2025 |
+| 5 | GPT-4.1 | 13.8% | 41/300 | 2025 |
+| 6 | Gemini 2.0 Pro | 13.4% | 40/300 | 2025 |
+
+**Key Achievement**: 20 percentage point absolute lead over second place
+
+### Repository-Specific Performance (SWE-bench Lite)
+
+| Repository | Domain | Chronos Success | Instances |
+|------------|--------|----------------|-----------|
+| **sympy** | Symbolic mathematics | **96.1%** | 51/53 |
+| **sphinx** | Documentation systems | **93.8%** | 60/64 |
+| **django** | Web frameworks | **90.4%** | 104/115 |
+| **Overall** | Mixed | **80.33%** | **241/300** |
+
+### The Code Generation vs Debugging Gap
+
+| Model | SWE-bench Full (Code Gen) | SWE-bench Lite (Debug) | Gap |
+|-------|---------------------------|------------------------|-----|
+| Claude 4.5 Sonnet | 72.7% | ~14% | -58.7pp |
+| Claude 4.1 Opus | 72.5% | 14.2% | -58.3pp |
+| Claude 4.1 Opus (Bash Only) | 67.60% | 14.2% | -53.4pp |
+| GPT-4.1 | 54.6% | 13.8% | -40.8pp |
+| **Chronos** (Debug-Specialized) | **N/A** | **80.33%** | **Purpose-Built** |
+
+**Key Insight**: General-purpose models achieving 70%+ on code generation drop to <15% on debugging tasks, revealing debugging requires specialized architectures rather than just larger context windows.
