GPT can generate high-quality texts, but due to its lack of human thinking and judgment, the generated texts often have problems such as logical errors, grammatical errors and improper semantics. This problem is easy to find, which exposes the fact that GPT is used to write papers. Writing papers with GPT also involves copyright issues. The text generated by GPT will involve other people's intellectual property rights, and improper use will infringe other people's copyright.
