I use it via minimax direct. I signed up when I heard they are open sourcing m2.7 weights, something that was looking not likely.
The token speed is low due to demand. They promise 100+ tokens/sec with high speed, but it is barely faster than standard. You do get a lot of usage though compared to others and it's a good model. I'm waiting for m2.7 weights to drop so I can run it on my RTX 6000 Pros. Should be any day now.
