Claude Fable 5: Master Anthropic's Most Powerful AI (2026)

Claude Fable 5 is Anthropic's most powerful publicly available AI model — and this hands-on crash course teaches you how to actually use it in 30 minutes. No fluff, no theory overload: just what Fable 5 is, where to access it, and the exact prompts that get professional results.

WHY THIS COURSE?

Fable 5 launched in June 2026 as the first "Mythos-class" AI model — a tier above Claude Opus — and made global headlines. It can code for days autonomously, read charts inside PDFs, and handle a 1-million-token context window. But most people use it like an ordinary chatbot and get ordinary results. This course fixes that.

WHAT YOU'LL DO (HANDS-ON):

• Fix a broken signup form by having Fable 5 write validation AND its own unit tests

• Upload a real quarterly report PDF and watch Fable 5 extract every chart figure — and catch a contradiction the report's text tries to hide

• Generate an executive research briefing in one prompt

• Build a working flashcard web app from a single instruction

Every project file, prompt, and a printable cheat sheet is included as downloadable resources.

WHAT YOU'LL LEARN:

The Claude model family (Haiku, Sonnet, Opus, Mythos-class), the difference between Fable 5 and Mythos 5, how to access Fable 5 on the Claude web app, Claude Code, Claude Cowork, and the API, the 6-Part Power Prompt framework, and the practical fine print: safety classifiers, the Opus 4.8 fallback, API pricing, and data retention.

WHO IS THIS FOR?

Developers, analysts, students, writers, entrepreneurs — anyone who wants real productivity from frontier AI without wading through hours of filler.
