Every's Vibe Check: Opus 5.5 wins back Codex converts at ~60% less than Fable
every · x · 2026-09-27
- Every published a Vibe Check of Opus 5.5: unlike the argumentative, rambling Opus 5, the new version impressed testers and dethroned Fable 5.1 as Kieran Klaassen's daily driver.
- Former Claude power users Mike Taylor and Tyler Nishida, who had switched to Codex, are reconsidering — Nishida: "My jaw dropped at least five or six times this week."
- Priced at roughly 60% less than Fable 5.1's token price, it's described as a "smaller Fable": faster and cheaper, great for big end-to-end coding projects, though writing still buries the point and some prefer Codex for knowledge work.
- Key thesis: lower AI costs make more tasks worth delegating to agents — extra code reviews, verification passes, speculative PRs — so cheaper models mean more tokens used.
