Claude Fable 5 just dropped and I'm speechless...

TL;DR

• 1

  Claude Fable 5 changes the core question from correctness to direction: Alex says earlier models made you ask "is Claude doing the work right," but Fable 5 is strong enough that the new bottleneck is whether it is doing the right work toward the right goal.

• 2

  Anthropic's playbook is to treat the model like a peer, not a junior assistant: The three tips he highlights are to use Claude as a thought partner, give it high-level goals instead of micro-steps, and be more ambitious about what you ask it to build.

• 3

  His recommended workflow is "advanced plan mode" followed by /goal loops: He first has Claude ask as many clarifying questions as needed, then pastes the resulting spec into /goal so the agent keeps checking itself against success criteria until the app is done.

• 4

  The demo app is intentionally big and still ships in one pass: Using Claude Code in Ghosty with Fable 5 on auto mode and high effort, he asks for a web app with local storage, deep integrations, a calendar, notes, Pomodoro stats, kanban board, and an arcade break game.

• 5

  The finished product actually works across all the requested features: Alex shows tasks, calendar events, week view, journal-style notes, Pomodoro streaks, drag-and-drop kanban, and a Snake game that records scores, and says it shipped with zero bugs.

• 6

  The pricing may signal a broader industry shift away from cheap subscriptions: Fable 5 is only in subscriptions until June 22, after which it moves to API-only access, costs double Opus, and Alex frames that as a possible sign that frontier models may stop being heavily subsidized.
