By Steven Van ·
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, now runs Claude Fable 5.1, 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.
