modelSettings
A Claude Code settings key, read out of the shipped bundle. It has been in the build since v2.1.239, including the newest one read.
What it is
A new modelSettings config key stores an effort level per model, from low to xhigh.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.239.
Presence across releases
| Releases | Reading | Declared type | Default |
|---|---|---|---|
| 2.1.245 – 2.1.250 5 releases | never mined | — | — |
| 2.1.239 – 2.1.243 5 releases | in the build | — | — |
A row reading never mined is a release with no archived bundle behind it. Nothing was read out of it, so nothing here says whether the name was in it. A declared type or a default is only ever what that release's own bundle stated.

Documentation pages
None of Anthropic's documentation pages this site has a copy of carries this name.
Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the settings key does. All settings keys.
