The age, people at which are suitable for these classes, is between 12-14.

I have a question about this sentence "the age, people at which are suitable for these classes, is between 12-14".

I've asked ChatGPT whether this sentence is grammatically correct and it said it isn't correct and the reason is that “which” cannot refer to people, only “who” can, but here this “which” refers to "age", so the full relative clause should be “people at X age are suitable for these classes”. And ChatGPT also said “The problem, the core of which is her decision, has been solved” this sentence is correct. Thus I suppose a structure starting with a noun and combing with a preposition can be used to start a relative clause. How is it wrong then?

It's incorrect but it's nothing to do with "which" for people. The correct construction is:

The age at which people are able/allowed to take these classes is twelve to fourteen.
The age at which these classes are suitable for people is twelve to fourteen.

Neither sentence is pretty but at least the words are in the right order!

1) The comma is wrong since the relative clause is defining.
2) Strictly speaking, 12 to 14 is an age range, not an age, so it's better to say that.
3) It's wrong to use 'between' with 'to'. You need either 'between/and' or 'from/to', or just 'to'.
4) You're right that 'which' is correct, since it refers to the age range of people, not the people themselves.
5) The main issue is the word order in the relative clause, namely the position of 'people'.

The age range at which people are suitable for these classes is 12 to 14.

Thank you for your response now I got it.

"the age, people at which are suitable for these classes, is between 12-14".

The age range at which people are suitable for these classes is 12 to 14.

For what it's worth, one could simply say:

These classes are suitable for people ages 12 to 14.​
