Not surprising considering Grok 4.7 is a 2T model, so Sol/Opus class, not Astra/...

How many parameters do Astra or Fable have?

5T I believe is the guess, though not sure its public anywhere.

I believe most speculation is that Opus is 5T model, Fable a 10T

Elon claimed Opus was 5T in April, and I think it's fairly likely this is accurate: https://x.com/elonmusk/status/2042123561666855235
