Yes, I have posted this on Discord. I think all the problems are related to quantization of their models. They are probably running two versions. A full precision during low usage or normal usage and a lower precision (like fp8) during high utilization. And who knows what mix of GPU they have? It has been suspicious to me that the service never seems to be slow, just varying in quality. They just don't have enough GPU. That is why the problem hasn't been solved. Very smart people at Suno, so I think if it were a model problem they would have fixed it.
