The Current State of AI Generated Text Detection

New articles are being released frequently discussing enhancements in language models. Models like GPT2 and BERT are able to mimic human text where even humans have a hard time distinguishing that the text was generated by a machine. As these models continue to improve, the ability for them to be used in a malicious way is increasing. Bad actors could use these models to automate phishing emails, impersonate a celebrity on twitter, or spread fake news. It is important that security researchers look to develop methods to detect machine generated text as a defense against these use cases. GROVER and GLTR are two state of the art frameworks in machine generated text detection. McAfee is working to utilize these frameworks as a way to detect machine generated text.
