Press x to doubt on the 45% number. The cheaper providers on open router are fp4 vs fp8 for official zai. There are some cheap fp8 ones (like novita) but the ui makes it seem like it's a temporary promotion, with their normal prices being almost equal to official zai (idk much about open router so not really sure what's going on with these discounts)
Yes it's true that it's not super clear whether these prices are permanent or short term promotions. On the other hand, there are so many providers making promotional offerings that you could probably easily switch from one to another should their prices go up?
