Yeah. I have a Max 5x subscription and Fable burned through 16% of my weekly quota in a 40 minute code review session. It didn't even finish the review, it switched back to Opus 4.8 in the critical memory safety parts where I actually needed Fable.

I feel like I'm going to get priced out of these models soon. I should probably try to get the most out of Fable until June 22nd.
