Claude Fable 5
Made for expressive, long-form writing
1.0M contextA little more room for your ideas
More room to create.
More models to choose from.
One monthly plan gives you a fresh model allowance every day and nearly 400 models to spend it on. Follow the story, change the model, try another path—without watching every token like a clock.

The model garden
Choose by feeling, not by vendor.
Frontier models, creative favorites, reasoning models, and tiny fast ones all use the same key and the same daily allowance.

1.3M contextThe catalog follows upstream availability. New models can appear without a new plan, and a model is only listed when Umbra has a complete rate and can account for it safely.
A fresh allowance every day
Pick the room you need.
Every plan includes the full model catalog. Wisp is a gentle place to start; the larger plans simply give you more room and concurrency.
