If you have a look at their headline benchmark on the post here, Grok 4.7 is hardly cheaper than Fable 5.1 Low and performs similarly.

Based on Artificial Analysis Cost per Task, Astra is about 2-3x cheaper than Fable 5.1 at Medium and Low.

Consequently Astra could be cheaper than Grok 4.7, depending on the task.
