tinyfool · x · 2026-07-03
User @waylybaye shared real-world data on the one-pass success rate of coding PRs (Pull Requests) across three AI models in daily use: Fable 5 at roughly 80%, Opus at 60%, and GPT 5.5 at 50%.
While this is an informal comparison based on actual engineering workflows rather than standardized benchmarks, it reflects developers' intuitive feelings about the code generation quality of these top-tier models in practice. Fable 5 holds a clear leading edge.
