Anthropic's model replaces Claude Fable 5 in Higgsfield's Supercomputer chat, with reasoning depth adjustable via an effort selector.

Higgsfield Supercomputer, part of [Higgsfield](<https://creatorstoolbox.com/tools/higgsfield>), now runs [Claude Fable 5.1](<https://higgsfield.ai/supercomputer>), Anthropic's successor to Claude Fable 5.

- Stronger on long agentic tasks: coding, multi-step research, and document work.

- Writing is clearer, more coherent, and more accurate at following guidelines.

- Adaptive thinking is always on; reasoning depth is set with the effort selector.

To use it, open Supercomputer and select Claude Fable 5.1.
