Use Fable in claude.ai
- You need a paid plan (Pro / Max / Team / Enterprise) — not the free tier.
- Pick the current Fable model in the model selector.
- Fable usage now meters against paid usage credits rather than a standing free inclusion. Long, heavy runs are the ones worth spending on.
Worth switching for: long-document analysis (1M context), complex multi-step reasoning, and reading charts and figures (vision).
Use Fable in Claude Code
Fable's headline strength is long-horizon autonomous work — planning across stages, delegating to sub-agents, and checking its own output over long runs. That maps directly onto Claude Code.
# In-session (saved as your default)
/model
# then pick Fable 5.1
# Or at launch
claude --model claude-fable-5-1- Give it bigger chunks of work. Its edge over cheaper models grows with task length.
- Route routine edits to Opus 5.5 or Sonnet 5.5 and save Fable for migrations, hard bugs and long investigations.
Three ways to keep using Fable
① Paid usage credits (official apps)
Stay in claude.ai / Claude Code and buy usage credits; they track API pricing, so heavy use adds up fast.
② Direct to the official API
Get a Claude Console key (international card required) and call claude-fable-5-1. Quickstart: fableapi.app.
③ A compatible endpoint ⭐
Claude Code officially supports custom endpoints. Configure once and everything keeps working:
export ANTHROPIC_BASE_URL="https://api.omniakey.com"
export ANTHROPIC_API_KEY="YOUR_API_KEY"
claude --model claude-fable-5-1A custom endpoint sees your code and conversations — vet the provider and think twice for sensitive repositories.
