cursor 升级到 1.0 之后，使用体验比之前差太多了

1.月订阅用户，将 500 次 fast 额度使用完之后，就完全不能使用 claude-4-sonnet 模型了，总提示：

Claude 4 is not currently enabled in the slow pool due to high demand. Please select another model, or enable usage-based pricing to get more fast requests.

2.使用 genimi-2.5 ，一直提示如下内容的错误，是我的节点有问题吗？我换了好几个节点都是这样，节点都是自建的，不是机场共用的：

3.目前只能使用auto、claude-3.5-sonnet或者gpt-4.1模型，你们有这个困扰吗？
