What
A fallback model is a second model Claude Code can switch to when the main one can't be used. Whether a default fallback applies now depends on two further things:
selfTargetDefaultFallbacksEnabled, a setting that Anthropic's servers provide
whether the fallback model is different from the main model
Why
This changes when a fallback is offered for a model whose fallback is the same model.
