Claude Fable 5.2 is in the model picker for everyone, with a 1M-token context and reasoning levels. Ultra now runs on it by default.

- **In the picker.** Claude Fable 5.2 is available to every workspace. Choose it for a chat, a project or a scheduled task, like any other model.
- **Ultra runs on it.** The Ultra preset now serves Fable 5.2 at high reasoning by default, so you get it without touching a setting.
- **Room to think.** A 1M-token context window and reasoning levels, from low to max. If a request gets refused, Viktor quietly retries it on Opus so your work isn't dropped.
