Opus 5 Lands Between gpt-5.6 and Fable, With Better Correctness
thesaraharminta · x · 2026-07-25
A quoted take on Opus 5 says the model feels like a middle ground between gpt-5.6-sol and Fable 5.
- It inherits a lot of Fable's style and taste.
- It also has gpt-5.6-like thoroughness and tends to take instructions very literally.
- The poster says it writes code that is a bit uglier than Fable's, but more often correct.
- It also catches mistakes that Fable misses.
Overall, the author sees it as a strong compromise between messy-but-thorough code and clever-but-sometimes-wrong code.
