Claude Code now defaults to Fable 5.1 as 'recommended' without user config
Capnjbrown · reddit · 2026-10-27
A Reddit user found Claude Code v2.1.310 defaulting sessions to Fable 5.1, marked "Default (recommended)", despite having no global config or settings.json overrides. The /model menu positions Opus 5.5 for complex work, Fable 5.1 for the toughest challenges, with Sonnet/Haiku tiers below and a /fast shortcut to Opus 5.5 Fast mode — suggesting Anthropic is quietly changing Claude Code's default model strategy.
