Anthropic Releases Official Prompt Guide for Claude Fable 5
CodeByPoonam · x · 2026-07-04
Anthropic has released the official prompt guide for Claude Fable 5, which operates quite differently from Opus. Users can set the Effort level—from minimal to extreme—directly in the prompt. Furthermore, it is recommended to provide the complete, complex task all at once rather than breaking it into smaller chunks; the larger the context space, the better the results.
