Claude Code bug secretly reverts model to Opus

A developer highlighted an ongoing issue with Anthropic's Claude Code where the application fails to persist the user's preferred model selection. Specifically, the tool repeatedly switches back to the Claude 3 Opus model on its own, ignoring the user's explicit choice to use Claude 3.5 Fable, and requires frequent manual intervention to correct.

// ANALYSIS

This highlights the importance of reliable configuration management in AI developer tools.

–Unexpected model switches can cause frustrating disruptions in a developer's coding flow.
–It could potentially lead to higher API costs if the forced default (Opus) is more expensive than the preferred model (Fable).
–Such bugs diminish the overall user experience and trust in the tool's reliability.
