Okay, the user wants me to translate "no-costs" into Thai. Let me check the rules again. The first rule says to translate all content into Thai. The second rule states that if the content is already in Thai, leave it as is. The third rule is to provide only the translation without any explanations.
So, "no-costs" is in English. I need to translate it. The direct translation would be "ไม่มีค่าใช้จ่าย" which means "no costs" or "no expenses." I should make sure there's no existing Thai term that's more appropriate. Since the user didn't specify any context, the straightforward translation should be fine. Also, the user wants only the translation, so I shouldn't add anything else. Let me confirm the spelling and grammar. Yes, "ไม่มีค่าใช้จ่าย" is correct. Alright, that's the response.
