A reminder of the speed of change in the world of AI, and that AI is critical infrastructure.

Last night I scheduled a post about Fable, as I'd continue to test it out on my more meaty problems overnight. I woke up to an error message and "Claude Fable 5 is currently unavailable."

Yesterday we were arguing over what exactly would happen after the June 22 end of general availability. Today we no longer have access.
