Fable 5.2 vs Opus 5.5: default to Opus, upgrade to Fable for long builds and messy context
every · x · 2026-11-10
Every published a vibe check comparing Fable 5.2 and Opus 5.5:
- Reach for Fable: software you plan to keep, visual projects, digesting mountains of messy context, long autonomous builds.
- Stick with Opus: fast back-and-forth iterations when time matters, tight token budgets, drafting/editing prose, small familiar builds.
- Kieranklaassen's rule: use Opus 5.5 for everything and move up to Fable only when you know you need better.
