Why When Fable 5 shipped, I ran a controlled comparison of Fable 5 and Opus 4.8 (an A/B set of 19 runs plus 26 real working sessions, 1,500 tool calls). The finding: - On closed, answer-bearing work (code, logic, builds), the two models were effectively tied. - The gap appeared only on open-ended work, and its nature was \"following an implication one step further.\" - That depth is model capability — it could not be transferred by instructions or a harness. An injection experiment confirmed it: Opus could not reproduce the defects Fable found on its own. - But the procedure of good work — actually running what you build, seeing it through, investigating systematically — does transfer. fablize applies only the procedures whose effect was verified. It does not raise the model's ceiling; it makes the model reach its own ceiling. What transfers and what doesn't Trait Transferable? Reason --- :--: --- Verification grounding (run & observe the artifact) ✅ shipped A procedure Opus skipped \"not because it can't, but because it didn't.\" Injecting it raised render-verification behavior measurably. Multi-story completion + evidence gate ✅ shipped A procedure — decompose, checkpoint, refuse completion without proof. Systematic investigation (reproduce → hypotheses → causal chain) ✅ shipped A procedu","default_branch":null,"files":null,"tree":[],"storefront":"/r/fivetaku","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/fivetaku/fablize/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
