Tip: Set fallbackModel in Claude Code to Chain Up to Three Models for Resilience
Claude Code Docs·medium signal
Recent Claude Code releases added a fallbackModel configuration that tries up to three models in order when the primary is unavailable or rate-limited. For long-running autonomous loops this prevents a single provider hiccup from killing a session mid-task. Pair it with a cheap model in the chain so degraded runs continue instead of erroring out.
