Bring back old Opus in Claude Code

I still use Opus 4.6 and 4.8 regularly, as I often find Opus 5 too verbose (and Fable too expensive). Here is how to add them back to the /model picker.

Add this to ~/.claude/settings.json. The rows appear after the built-in ones:

"modelPicker": {

"options": [

{ "model": "claude-opus-4-8", "label": "Opus 4.8" },

{ "model": "claude-opus-4-6", "label": "Opus 4.6" },

]

}Set

modelPicker.replaceBuiltInOptions: trueto show only these rows.
