Cline v4.1.8 adds support for Fable 5 on Vertex and lets you manually enter any Vertex model ID, including unlisted ones. The model picker now shows the full catalog for each Vertex region instead of a filtered list, with helpful error messages if a region doesn't support your choice. CLI v3.0.53 includes Fable 5 in the Vertex catalog with unknown pricing to avoid region-dependent billing errors.
