M3 in Minimax Token plan which worked great before, is now unusable

I've been using the MiniMax Token Plan for a while, and M3 used to work great. Previously, I could use M3 for around **1.5 hours of continuous work** within the **5 hour** token window before exhausting my quota. Now, with essentially the same workload, the quota is depleted in about **15 minutes**.

What's even stranger is that the console dashboard still reports a **99%+ cache hit rate**, so this level of token usage seems practically impossible. It feels like either token accounting has changed significantly or there's a bug.

Has anyone else experienced this recently, or has MiniMax commented on it?
