> Anyone using them now?

You're gonna have a had time getting straight answer to that out of the internet. There are now 4 different flavours of the Max plan floating around (Legacy V1, Legacy V2, New plans, and the current credit ones). And on top of that they have peak times. So ~8 scenarios, 24 in total across all feedback for their coding plans.

So when someone tells you they're having a good time on a GLM coding plan it's damn near unusable as a datapoint unless both parties are very clear about what precisely is being discussed

[It's been good for me though...V1 Max off peak...which is basically the best of the 24]
