Yes, but the Artificial Analysis result is also from GLM 5.2 (max), not high.
They have this with a lot of models, measuring only the max setting, while the one you'd actually want to use for most tasks is much lower.
For the brief period with had Fable, I never had to use it above medium.
Low nailed the overwhelming majority of mundane tasks on it's own, medium was good for more complex stuff.
