Large-Scale Refactoring Tested: Fable 5 More Stable
RFOK · reddit · 2026-07-14
The author compared GPT-5.6 Sol and Fable 5 on large-scale coding/refactoring tasks, including multi-file zips, long-chain refactoring, and automation scripts.
Conclusions:
- GPT-5.6 Sol is good for demos but often yields results that look correct but are actually off in large tasks.
- Fable 5 follows instructions more reliably, especially in multi-file and complex refactoring scenarios; the author finds it more "respectful of requirements" and stable in execution.
The core of this post is not a specific coding tip but the author's subjective comparison of the two models in real refactoring tasks.
