/model to open the model picker. The live catalog shows the choices available to your account; model availability and defaults can change.
Choose one model for all phases or set a phase separately. In clients that support model command arguments,
/model all <model> applies one model throughout and /model reset restores automatic choices. Use the picker to select a valid model identifier.
Model settings persist with the project. A phase selection only matters when that phase runs; effort determines the sprint workflow.
/pro has been retired. Use /model for model selection. The Pro subscription is a billing plan and is separate from these controls.
