In my experience, Fable is not even close to Sol 5.6 High (not even the max tier) for coding.
1) it's substantially slower.
2) it's substantially more expensive.
3) it's code is considerably worse.
It's a joke when you consider what you get for what you pay for.
This is very interesting to me because I find sol to be inferior at code generation, but superior at conversation and code review.
