Hey, thanks for the question. There’s an important nuance here.
嘿，感谢提出这个问题。这里有个重要的细节需要注意。

Yes, this is an intentional change. On the legacy request-based plan, frontier models are only available for manual selection via Max Mode, and they’re billed at the model’s token rate. This rule is tied to the plan and the frontier category, not to the price of a specific model.
是的，这是一个有意为之的改动。在传统的基于请求的计费模式下，前沿模型只能通过“Max 模式”进行手动选择，并且它们的费用按照模型的代币价格来计算。这一规则与计费计划和前沿模型类别相关，而不是与某个特定模型的定价有关。

That said, you’re not losing access to strong models. Auto mode will still route to current models within your included requests and will pick up new ones as older ones get phased out. So you won’t end up in a situation where you have no access to powerful models at all. Max Mode is specifically for direct manual selection of the newest frontier models.
不过，你并不会失去对强大模型的访问权限。自动模式仍然会优先选择你已订阅的模型，而新的模型则会在旧模型被淘汰后逐步被引入。因此，你不会遇到无法使用强大模型的情况。而“Max 模式”则专门用于手动选择最新的前沿模型。

If you want flat-rate access to the newest models without Max Mode, that’s on the current token-based plan.
如果你希望获得最新型号设备的固定费率访问权限，而不需要“Max 模式”，那么可以选择当前的基于令牌的套餐。

On a cheaper way to get new models on the legacy plan, I hear you and I’ll pass the feedback along. I can’t share any timeline or policy changes right now, so I won’t promise anything.
关于如何以更便宜的方式在旧计划下获得新型号的问题，我明白了你的想法，我会把反馈信息传达下去。目前我无法透露任何关于时间表或政策变化的信息，所以无法做出任何承诺。
