Unclear It is not known when this conversion happens, so it is unclear which sessions get thinking despite a disabled setting.
What
Thinking is the model's step-by-step reasoning before it answers. Claude Code's handling of a thinking setting of disabled changed. Under a certain condition, and when the setting is not marked as mechanical, it now becomes adaptive instead. In some cases the display is set to summarised, and an explicitly chosen display is kept.
Why
In some situations the model may think even though thinking was set to off.
