Claude Fable 5, Anthropic’s newest coding model, returned to the subscription after a brief removal over security concerns. Subscribers can now access it, but Anthropic caps usage at 50% of weekly limits, so you can’t run it on every task or you’ll quickly hit the ceiling.

To stretch those limits, use Fable primarily for planning and refactoring, not direct code implementation. Your workflow: 1) Ask Fable to map out a feature or bug fix, 2) Employ Claude Opus 4.8 or GPT-5.6 to write the code, 3) Review with GPT-5.6, then merge.

When planning, describe the goal, let Fable scan the repo, suggest architecture and logic, and output results—ideally with visuals. This keeps the heavy lifting in the middle, where Fable excels, while saving tokens for the high‑value planning phase.

Refactoring is triggered when implementation slows or bugs rise. Prompt Fable: “Find refactoring opportunities in this repository; eliminate repetition, improve separation of concerns.” Focus on specific areas you’ve noticed lagging, and let Fable recommend changes before coding.
