Vibe check: when to use Opus 5.5 vs Fable 5.1 vs Astra/GPT-5.6 Sol
every · x · 2026-09-23
- Reach for Opus 5.5: visual/inspectable builds (interfaces, prototypes, 3D scenes, games), creative writing collaboration, and persona/negotiation/point-of-view analysis.
- Stay on Fable 5.1: problems too big to eyeball, deliverables that must be right the first time, or if you prefer Fable's prose.
- Keep Astra or GPT-5.6 Sol nearby: tight deadlines, editing rather than writing, or no set budget — "Opus will take the afternoon if you let it."
