Chronos-1 vs General-Purpose Models
A detailed comparison showing why general LLMs fail at debugging and how Chronos is engineered for repository-scale repair.
General-purpose models are optimized for code generation, not debugging. This leads to major performance gaps when dealing with real-world failures, multi-file bugs, and repository-scale reasoning.
Key Differences
Training Objective
- General LLMs: next-token code completion
- Chronos-1: debugging, diagnosis, and root-cause reasoning
Context Handling
- General LLMs: rely on large context windows
- Chronos-1: uses Adaptive Graph-Guided Retrieval (AGR) to assemble only the relevant repository context
Fix Reliability
- General LLMs: single-shot patches, often unvalidated
- Chronos-1: multi-iteration fix → test → refine loop
Memory
- General LLMs: stateless
- Chronos-1: Persistent Debug Memory (PDM) that learns over time
Performance Gap
- General models achieve 13–15% debugging accuracy
- Chronos-1 achieves 67.3% real-world fix accuracy and 80.33% on SWE Bench Lite
Chronos-1 succeeds because debugging requires specialization, not scale.
