What Muse Spark 1.3 is used for
Language models are general-purpose. The same model that drafts your emails will summarise a contract, answer support tickets, write code and route a workflow — the differences between the top models show up on long tasks, strict instruction following, tool use and cost at volume rather than on simple prompts. For anything customer-facing, verify the model on your own examples before you commit: benchmark wins do not always transfer to a narrow, well-defined task.
