Kimi K3 has 104B active params, by the way. Where did your 650B active params estimate come from? The only thing I can infer from Anthropic API prices is Fable is roughly twice the size of Opus.
Also which prices are you indexing on? Anthropic listed different rates for Mythos (in the Glasswing announcement) vs. Fable (on their pricing page).
