Understand the Muse Wonder options

The model, Meta’s own coding product, and the experience inside Julius are different things. Use this distinction to choose the access path for your task.

Muse Wonder inside Julius

Muse Wonder 1.0 is the model-menu choice covered here. Try a file-based task such as reconciling invoices, then inspect the exceptions and totals.

Wonder Full and Muse Code

Meta also describes Wonder Full through Muse Code. Selecting Muse Wonder in Julius does not give you that separate product. Check Meta’s release for those access details.

Native inputs and app support
