Three doors to Fable

Same model behind each — pick by how you work. If you're on a subscription plan, mind the July 7 date.

Updated July 2, 2026. Fable 5 was restored worldwide July 1 after the June suspension. Pro/Max/Team plans include it at 50% of weekly limits through July 7; usage credits apply after. Live availability: fableguide.com/status, part of our dedicated Fable 5 guide. Latest news →

Door one: the Claude API

For builders. Restored July 1 after the June suspension — $10/$50 per million tokens, no waitlist, no window, and the same claude-fable-5 id as before.

  1. Get an API key at platform.claude.com (Console → API keys).
  2. Install an SDK: pip install anthropic or npm install @anthropic-ai/sdk.
  3. Set ANTHROPIC_API_KEY in your environment — never in code.
  4. Make your first call with model="claude-fable-5".

Then go straight to the cookbook — especially prompt caching, which is what makes $10/MTok input affordable at scale.

Door two: Claude Code

For anyone who'd rather use Fable than call it. Fable 5 powers Claude Code — the terminal CLI, desktop app, web app, and IDE extensions.

  1. Install from claude.com/claude-code (or npm install -g @anthropic-ai/claude-code).
  2. Run claude in a project directory and sign in.
  3. Give it a whole task — goal, constraints, what "done" looks like — in one well-written message. That's where Fable's long-horizon strength shows.

Door three: claude.ai subscriptions

The window (updated July 2, 2026): on Pro, Max, Team, and select Enterprise plans, Fable 5 is included at 50% of weekly usage limits through July 7, 2026. From July 8 it requires usage credits. Treat this week as the trial: run your hardest real task and decide if the credits will be worth it.
  1. Open claude.ai and pick Fable 5 in the model selector.
  2. Bring a real problem — Fable's difference shows on hard tasks, not greetings.

Moral: doors don't matter much when it's the same room. Pick the one nearest your desk.
