+The setting vary a bit between build frontends.
 
-* `-1`: Hide as much build output as possible; passes `-q` to the build backend. Not supported by `build`/`build[uv]`.
-* `0`: The default. On pip, this hides the build output if the build succeeds, other build backends produce output from the build backend.
-* `1`: Produces build backend output. On `pip`, this passes `-v`. Other backends do this by default.
-* `2`: Produces extra output from resolving packages too. On `pip`, this passes `-vv`, other build backends use `-v`.
-* `3`: Even more resolving output from pip with `-vvv`, other build backends continue to just pass `-v`.
