Bundled model catalog updated to version 629 with model reassignments across ccr, ccd, and other surfaces
The bundled model catalog that Claude Code ships with was updated from version 554 to version 629, with a new issue and expiry window. Several catalog surfaces, including ccr and ccd, had the model assigned to their existing slot swapped between claude-fable-5-1, claude-sonnet-5, and claude-opus-5.
This changes which model a given surface falls back to when using the bundled catalog, continuing the same kind of reassignment seen in earlier catalog updates for ccr and ccd.
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

The finding does not specify which surfaces ended up on which of the three models after this swap.
Anthropic's documentation has since written up claude-opus-5, on skills-guide.
