Fable 5.1 Low Effort Mode Optimizes Knowledge Workflows

This article discusses the practical use of Claude Fable 5.1's effort level settings for knowledge work. The author recommends starting complex tasks on the 'Low' effort setting to leverage its cost efficiency and ability to create initial drafts, such as an Excel workbook with formulas and a PowerPoint deck. The 'Low' run provides a baseline that can be reviewed and refined using higher effort settings for specific parts requiring more judgment. The article highlights the model's effectiveness in building workbooks and decks from brief prompts, while noting limitations like missing source documentation, which the 'Extra' effort mode helps address. It also compares Fable 5.1's performance with another model, Sol, in certain tasks. The author provides practical guidance on prompting for knowledge work, emphasizing that building artifacts like spreadsheets aids in understanding the business better, and outlines workflows for long tasks.
