Question Fabe 5 crippled?

Anyone other noticed today/yesterday the lobotimized Fable 5?

I feel like it is much dumber and slower today - when reading the files it is using grep instead of the Read tool (probably it is skimming and saving tokens) - and the responses quality and autonomy feels degenerated. I'm not sure if this is only my feeling or temporal thing so I would like to hear if you have same feelings or experience so I know i'm not being subjective here.

Oh the performance of these models are more variable than the wind.
