When To Use Fable 5.2 or Opus in Claude Code (Full Tutorial)
Peter Yang, drawing on over 500 hours of use, explains when to pick Fable 5.2 or Opus inside Claude Code, walking through five real use cases from inbox triage to helping his mom through cancer.
The gist
-
Yang's rule: Opus is the daily driver, while Fable is for the hardest, most important work, since it costs twice as much per token on the API.
-
His Opus chief of staff checks email, calendar and sent mail from the last seven days, ranks urgent items, and runs daily at 7 a.m. and 4 p.m.
-
He runs a career advisor on Fable, grounded in a personal plan listing goals, principles and what gives or drains energy, and asks it to be blunt.
-
With Riverside and Suno connected to Claude Code, he made a podcast sizzle reel with custom music in about 20 minutes instead of a full day.
-
Yang uses Fable for his mom's cancer care brief and for audits, such as reviewing 149 past sessions to improve his skills.
