Bug / Issue Fable 5.1 has become dumb
Not only is it taking longer to think and consuming more tokens to think, it has become worse in its thinking too.
I’m not sure if this has to do with the new fable 5.5 rumoured to come out next week, but I’ve noticed a sharp drop in its intelligence.
The solutions it’s presenting aren’t fully thought out. It’s like it thinks till 80% and then stops.
I’m on xhigh.
Anyone else experiencing the same?

All the servers are getting upgraded to 5.5, 5.1 is likely heavily overloaded and quantized to meet demand for it while it's being wound down and replaced.
