Every's Opus 5.5 vibe check: the model pulling Codex converts back to Claude at 60% of Fable's price
every · x · 2026-09-26
Every.to published an in-depth vibe check of Claude Opus 5.5, finding it strong enough to win back team members who had switched to Codex.
- Opus 5 was hard to love: argumentative about changes, over-verbose explanations, slow on simple tasks
- Kieran Klaassen says Opus 5.5 dethroned Fable 5.1 as his daily driver, sometimes slightly better
- Former Claude power users Tyler Nishida and Mike Taylor are reconsidering their Codex switch; Nishida's "jaw dropped five or six times" in a week
- Example: Nishida built an AI-friendly Origami Studio prototype in about 4 prompts, then added a swipe interaction via Claude Code
- Dan Shipper calls it a "smaller Fable"—faster, cheaper, great for end-to-end coding but he still prefers Codex for knowledge work
- Roughly 60% of Fable's token price; still buries the point in writing and can get carried away
