使用 ChatGPT 有费用吗？

From my experience, there's a free tier but if you want more features or usage, you gotta sign up for the paid plan.

The chat interface is free but if you want to integrate with other services or do custom stuff, that’s where charges come in.

I think it depends on how much you use it. For small stuff, free is enough, but for heavy usage, you gotta pay.

Just to add, OpenAI sometimes changes the pricing, so keep an eye on their official page if you care about the costs.

I heard the free plan has some cooldowns too, like you can’t spam requests nonstop.

I think ChatGPT charges mostly come if you use the API for your apps, not regular chatting.

Honestly, I just use the free one. No issues so far, but I don't do anything heavy with it.

I didn't pay anything for a while, but recently some features got locked behind a subscription. Not sure if everyone sees that though.

They have a free version but if you want faster responses and priority access, you need to pay for ChatGPT Plus.

您也可以访问 ai-u.com 查看新的或流行的工具。他们有时会比较这些 AI 平台的价格，这很方便。

说实话，我只是很高兴他们提供任何免费的使用。像这样的人工智能技术不应该只被锁在付费墙后面。

我试用了一个月的付费计划，只是为了测试，它挺不错的，但取决于你是否真的经常使用它。

免费套餐对每日使用有一些限制，所以如果用完了，只能等到第二天或升级。
