I think using ChatGPT is the same as using anything on the internet, so your conversations with students should be the same. Just like most things on the internet (Google, ChatGPT, etc.), tools can be used to help you understand or help you get the answer. Students need to know that ChatGPT and other online tools should only be used to help you develop your answer... not create your answer. Personally, as a math teacher, I find ChatGPT harder to use in the classroom, unless a student searches "HOW do you find..." because they're confused and they want to understand the process to find the answer. But using ChatGPT to plagiarize in any way is definitely unacceptable. A discussion about being a responsible student can be tied into that, as well. You know you cannot cheat by looking at someone else's paper, so it's also unacceptable to copy a response from ChatGPT word by word to use as your own.
The strategy I'd use would be "Decide on what is acceptable and what isn’t for your assignments". Students will always try to cheat to quickly finish a homework, finish a homework that they don't understand, finish a homework they don't want to put any effort towards, etc., so why not allow them to use the tool to use it to help teach themselves. I would make it known that I can easily spot when students are copying step by step, because it will look nothing like we learned, and emphasize that plagiarizing is not acceptable. Students will be allowed to use ChatGPT on two conditions: 1) They've attempted to solve the problem on their own first 2) They do not plagiarize any work from ChatGPT.
